How to Fix Windows 10 Error 0x800488AB

Code 0x800488AB – What is it?

The Error Code 0x800488AB will appear when a user is in the Windows 10 Mail app and has provided an Outlook.com e-mail address. The mail app will give a message that the “account information is out of date” and it does provide an option to fix the issue. After clicking the Fix button, this error code will show up to the user.

Common symptoms include:

  • A dialog box will appear with the Error Code 0x800488AB
  • Microsoft Windows 10 Mail App will not retrieve (or subsequently send) mail
  • User cannot delete and re-add the Outlook email account in the Windows 10 Mail app
  • User can still access and log in to various Microsoft websites, including logging into the Outlook Mail website

Solution

Restoro box imageError Causes

This error can be caused by a few different actions of the user when they have changed a password or a PIN number to access their Outlook mail. This error does have a relatively easy fix after the cause is determined and where the break-in information has occurred. A few of the causes may be:

  • If the user changes their password on the Microsoft website and uses the alternative PIN login method to access the Mail App.
  • The log-in information on the Microsoft website does not match the login information on the Windows 10 App.
  • The login information was changed on the Microsoft website and was not updated to reflect on the Windows 10 Mail app.

The Microsoft website and Microsoft Mail app do not share the knowledge of the change in login credentials, therefore the log-in credentials appear to be incorrect when trying to access the Microsoft Mail app. It should be noted that a user may bypass the password option if they log in to the Microsoft Mail app while using the alternative PIN log-in method, thus still leaving the password undetected.

Further Information and Manual Repair

As is the case with all new technology and having a few wrinkles, the release of Microsoft Windows 10 is not left out. There have been a few discussions of errors and bugs, including Error Code 0x800488AB. As of right now, there are three different methods that can be utilized by any at-home user. These methods are rather simple and make sense when the problem has been identified.

Method 1:

Run the built-in Windows Store Apps troubleshooter:

  1. Press the Windows Key and then type ‘troubleshoot’ and hit Enter
  2. Select “View all” on the left panel and run the “Windows Store Apps” troubleshooter from the list displayed and see if it works.

Method 2:

Use the System File Checker tool to repair corrupted or missing system files:

  1. Click Start.
  2. Type cmd, and then press CTRL+SHIFT+ENTER to open the elevated command prompt (I.e. Command prompt with administrative rights).
  3. The User Account Control window should appear, be sure that the action it exhibits is correct, and then press the Continue button.
  4. Type or copy-paste the below command line into it without quotes:

“Sfc /scannow”

Method 3:

  1. Press the Windows Key
  2. Search for "Credentials Manager"
  3. Click on Windows Credentials
  4. Look for any reference to your windows account (generally your @outlook.com is listed)
  5. Delete them.
  6. Then select your account at the top of the start menu and select Log Out.
  7. If using a Pin Code, switch to type input and put your password into the box.

When you go to Mail, and select "Fix Issues" it will detect your password and your account should sync with new emails. In some cases, depending on why this particular error code was caused, you may have to use a powerful automated tool to have it resolved.

AI and neural networks are more and more being used in all parts of our lives. From face detections to deep fakes it is both amusing and frightening to watch at the same time. From some really bad uses of neural networks and AI overall, looking at you deep fakes, upscaling videos or images are mostly harmless pieces of work not harming anyone. There is one cool YouTube channel, well there are more but this one seems to have most of the videos on it and if I am wrong I apologize. https://www.youtube.com/channel/UC33rC3GO1UZFAkMcCCwjyWg So upscale is like previously mentioned a YouTube channel that hosts old game trailers and into videos but in full 4K or 8K video resolution, fully upscaled using neural networks. There are some videos that are not maybe top-notch but the large quantity of them is pretty well upscaled and they do indeed look great. So if you have some time and want that old nostalgia fix, go and check it out. You might find something that will bring that old you out and you might even drop a smile or two remembering old good days, I know I have.

Website isn’t responding to connection
If there are any third-party add-ons or proxy settings that interfere with your Windows 10 computer’s internet connection, then you will most likely encounter a problem where you see an error message saying, “Website is online but isn’t responding to connection attempts” when you try to run the Network Adapter troubleshooter. Like pointed out, this kind of error can be caused by some proxy settings that prevent the connection. On the other hand, it could also be caused by some third-party add-ons. To fix this error, read on as this post will guide you on what you can do to fix it. You can try to turn off the proxy settings or disable the add-ons on your browser. You can also try resetting both the TCP/IP and DNS as well as reset the network. For more details, refer to the options provided below.

Option 1 – Try to turn off the proxy settings

There are some users who reported that they’ve fixed the problem after they’ve disabled the use of a proxy server using the built-in way. Follow the steps below to disable the proxy server.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
  • After that, go to the Connections tab and select the LAN settings.
  • From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
  • Now click the OK and the Apply buttons.
  • Restart your PC.
Note: If you are using a third-party proxy service, you have to disable it.

Option 2 – Try disabling the add-ons or browser extensions

The next thing you can do to fix the problem is to disable any extensions or add-ons on your browser. For instance, if you are using Chrome, here’s what you have to do:
  • Open Chrome and press Alt + F keys.
  • Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
  • Click the Recycle bin and select Remove.
  • Restart Chrome and press Alt + F keys again.
  • Proceed to On Startup and mark Open a specific page or set of pages.
  • To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.

Option 3 – Try to update the Network Adapter Driver

Follow the steps below to update your Network Adapter Driver:
  • Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
  • From there, expand the list of all the network drives and update each one of them.
Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Option 4 – Try to reset the TCP/IP and the DNS cache

As you know, the TCP/IP or the Internet Protocol is the most important thing if you want to use the internet on your computer. That’s why if it ends up getting corrupted, you need to reset the TCP/IP to fix the problem. To reset TCP/IP, refer to these steps:
  • In the Windows start to search, type “command prompt” and right-click on Command Prompt from the search results.
  • Then select the “Run as administrator” option to open Command Prompt with admin privileges.
  • After that, execute this command: netsh int ip reset resettcpip.txt
  • Next, execute this second command: ipconfig /flushdns
  • Once it’s done, exit Command Prompt and restart your computer and then check if the error is now fixed.

Option 5 – Try to reset the Network

You can also try to perform a Network Reset to resolve the problem. This will reset the entire network configuration including your IP address. To perform Network Reset, follow these steps:
  • Tap the Win + I keys to open Settings.
  • From there, go to the Network and Internet section.
  • Next, scroll down and look for “Network Reset” under the status pane.
  • After that, click on Network Reset and then on Reset now to start resetting the network configuration. Once done, check if it is able to fix the error or not.

How to Unmerge the User folder in Windows 10
The Windows 10 system allows users to change the default location of the User folders to another drive. This is probably to make sure that the files stay safe in case the system suddenly crashes. However, in some cases, while changing the path to another drive, for instance, the D drive or any folder, the Windows system recognized it as a hard drive as well so even though the files will be saved on that folder, it will appear as a hard drive in the Windows Explorer or look merged with another folder. It could also be that you had dragged and dropped a user folder to another user folder by accident. So if you’re wondering how you can unmerge the User folders, read on as this post will guide you on how exactly you can do that. Take note that even if you try to use the File History to restore the User folders, it still won’t work and you won’t be able to move them back to their previous locations nor restore the folders back to their previous versions and it would only state that they are not available. In the instructions given below, we are using the Downloads folder as an example.
  • Step 1: Tap the Win + R keys to open the Run dialog box.
  • Step 2: Next, type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Step 3: After opening the Registry Editor, navigate to the following registry key:
ComputerHKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders
  • Step 4: Then double-click on the multi-string value {374DE290-123F-4565-9164-39C4925E467B} located in the right hand pane. And in the Value Data, copy and paste the following value:
%USERPROFILE%Downloads
  • Step 5: Now click OK and close the Registry Editor.
Note: Look close enough and you’ll see that the multi-string values belong to each one of the folders. From there, you have a Desktop, Favorites, Skydrive, Music, Pictures, and many more.
  • Step 6: Restart your computer. After that, the operating system will pick up the new folder location during the startup. Here are the values for the other folders:
Music – {1CF1260C-4DD0-4ebb-811F-33C572699FDE} Pictures – {3ADD1653-EB32-4cb0-BBD7-DFA0ABB5ACCA} Videos – {A0953C92-50DC-43bf-BE83-3742FED03C9C} Documents – {A8CDFF1C-4878-43be-B5FD-F8091C1C60D0} Desktop – {B4BFCC3A-DB2C-424C-B029-7FE99A87C641}
  • Step 7: Now all you have to do is to change the location correctly. Start by tapping the Win + E keys to open the Windows File Explorer.
  • Step 8: After that, right-click on the Downloads folder located in the right-hand pane.
  • Step 9: Then click on Properties and go to the Location tab then type “D:\Downloads” in the location box.
  • Step 10: Click the Apply button and then the OK button to save the changes made. Doing so would ensure that not only the Downloads folder is restored but also that it does not stay merged to another folder or appear as a drive.

How to be a healthy PC gamer

Spending a large amount of time working or gaming in front of the computer can take a toll on your health. And as someone who indeed spends a large amount of time in front of the computer, I would like to share some insights about how can you be happy and healthy at the same time by incorporating some practices and habits.

gaming

Get good chair

This is first on the list because it matters the most. A proper sitting chair is essential for back health. If your budget allows it, do yourself a favor and get an anatomic sitting chair or gaming chair with lumbar support. It costs but it is worth it.

Learn to sit properly

As the important chair is, sitting properly is also as important as much. Your spine believe it or not is a very important part of your body and you need to take care of it. Sadly long periods of sitting sessions are bad for muscles around the spine that could reflect on the spine itself. Keep your back straight and keep your head not down nor up, place it in a position like when you are walking so the spine that is going from your head is in line with the spine on your back.

Stretch

By medical standards, each hour of sitting should be accompanied by a stretch session since sitting itself is placing too much pressure on certain muscles and blood circulation is lowered. Changing leg position and doing just a little stretch each hour can be really beneficial for your health in long run.

Take breaks

Yes, playing games is fun and most of the time we do not want to stop playing, especially if we are winning but taking breaks is essential for your personal health. Old saying goes that overdoing anything is bad and this applies true even to things that we do for pleasure and relaxation. Take periodic breaks to stretch, stand up and maybe even walk just a little.

Drink water

During long work hours or long gaming sessions, it is not uncommon that we are so focused on our activity that we forget to take our water intake. Approximately 2liters of water per day is needed for an adult person to function properly during that day and if you spend long times in front of a PC do not forget to drink water.

Do not neglect your daily tasks

As enjoyable as it is gaming can make us forget about our daily tasks, do not neglect your life and your tasks. Remember, gaming is only OK if it does not interfere with the daily things that you need to do. Do not postpone going for groceries because of gaming, do not switch shower for another level in the game. Do all of the things you must do first and then sit and game.

Take care of yourself mentally

Having mental health is as important as having a physical one. Playing games is fun, but playing games with someone is even better, do not forget to socialize and invite some friends so you can share some fun times together. Also, detach yourself from outcomes that will come because of gaming, this is very important for gamers that do a lot of PVP games and get annoyed and angry when they lose or when some other player is talking trash. Remember, gaming is for you to relax and enjoy, not to stress you.

What to do if Windows 10 PC turns on by itself
A PC that turns on by itself every so often can get quite annoying. Many users have faced this problem countless times. There are lots of possible reasons why your Windows 10 PC turns on by itself, wakes up from sleep, standby, or even when it’s shut down. To find out what exactly woke your computer, simply open Command Prompt as admin and type the following command:
powercfg –lastwake
Once you enter the command given above, it will show you the last device that woke your PC up. After that, you need to type in the next command:
powercfg –devicequery wake_armed
After entering the command, it will show you a list of all the devices that could wake your PC up. The goal in running these commands is to understand the reason what’s really causing your PC to turn on and see the reason is on the hardware level or not. Here are a couple of options you can try if your Windows 10 PC turns on by itself.

Option 1 – Try disabling Fast Startup

As you know, Windows 10 comes with a mode called Fast Startup which does not turn off the computer in the usual manner. This mode keeps your computer in a mixed state so that when you turn it on again, it will be a lot faster. However, as useful as this feature appear to be, some security experts find this an issue, for numerous reasons – for one, it can turn on your Windows 10 PC by itself. Thus, you need to disable this feature to fix the problem.

Option 2 – You need to stop the Task Scheduler from waking up your computer

There are times when the issue has something more to do with the software than hardware. It could be that you are using a Scheduled Task to get some work done on your computer at a particular time of the day or many times a day. That’s why if you really are using Task Scheduler, you need to change the Power settings of Windows to make sure that it ignores those tasks rather than deleting them instead when your computer is either on Hybrid or Standby mode.
  • Open the Power Options and then click on “Change Plan Settings”.
  • After that, make sure to choose the correct power plan and then select the “Change advanced power settings” option.
  • Next, look for the Sleep tree and expand it to view the “Allow Wake Timers” option and then disable it. Disabling this option will make sure that none of the program that could wake your PC up when it’s either on shutdown or sleep mode. However, this only applies to laptops.

Option 3 – Try to disable Automatic Restart

There are instances when the computer crashes and the system restarts itself. This is actually by design – when your computer has been left on standby, the computer will restart and if the program repeats, it will keep on waking your PC up.
  • In the Search bar, type in “system”.
  • Once it appears from the search results, click on it.
  • Next, select Advanced system settings on the left side and then go to the Advanced tab.
  • From there, click on Settings under Startup and Recovery.
  • Then unmark “Automatically Restart” and click on OK.

Option 4 – Adjust the Power Management option of both the Keyboard and Mouse

As you know, two of the culprits in waking your PC up are the keyboard and the mouse. If they’re slightly moved or hit, your PC turns on. To prevent these two from waking your computer up, you need to make some adjustments to their power management option since they have one. You can disable this option to ensure that they won’t wake your PC up unless you really want it to.
  • Tap the Win + X keys and then tap M to open the Device Manager and list all the hardware on your computer. From there, select your keyboard or mouse.
  • Next, right-click and then go to Properties and go to the Power Management tab.
  • In this tab, uncheck the “Allow this device to wake the computer” box.
Note: Aside from the keyboard and mouse, if you are also using any gaming rig to play games on your computer, then you might have to disable their power options as well as they could also wake your computer. Just make sure that either the keyboard or the mouse has the ability to wake your computer up at the very least as it can be quite inconvenient to tap the Power button every time you want to turn on your computer.

Option 5 – Modify Wake On Lan

The Wake On Lan feature can bring back your computer online if it is connected to a network. This feature is useful especially when a computer wants to communicate or to send data or files to a network computer which should come online only when it’s requested. Wake On Lan is built into the hardware, i.e. network adapter so it is one of the possible reasons why your PC turns on by itself.
  • Tap the Win + x keys then hit M to open the Device Manager and then under the Network adapters, look for the one that was listed above. Take note that you must not change anything with the ones that are listed as Miniport.
  • Next, right-click and select Properties and then go to Power management and from there, uncheck the “Allow this device to wake up the computer” option. This will ensure that no PC on the network can ever wake your computer up.

Option 6 – Prevent any scheduled Windows Update and Automatic maintenance

It is also possible that the Windows Update has restarted your PC to complete the update. This depends on your active hours or a predefined schedule. AS you know Windows has a built-in Automatic Maintenance mode which wakes the computer up at the scheduled time and performs the system update. This could be one of the possible reasons why your computer turns on by itself. so to prevent any scheduled updates and maintenance, you can simply change the time for Automatic maintenance. How? Follow these steps:
  • Open Settings then go to Windows Update and Security >Windows Update and select Active Hours.
  • After that, type in “Automatic maintenance” in the search bar to change the time for Automatic maintenance.
  • From there, you can adjust the timing or just uncheck the “Allow scheduled maintenance to wake up my computer at the scheduled time” box.

USB Security key is not working on Windows
As you know, the USB security keys are a secure medium to validate a lot of components in a computer. They can be used to log in to Windows 10. Now with the advancement of APIs, you can authenticate across the website as well using the same key. However, there are times when it may not work and it could be caused by several factors. It could be due to corrupted or incompatible drivers or it could also be due to compromised integrity of the key, and many more. So if you happen to encounter an issue with the USB security key on your Windows 10 computer, then there are several potential fixes you can try. You can try toggling the Internet Options settings or reinstall the respective USB drivers. You could also try changing the PIN of the security key or disable the antivirus program on your computer or troubleshoot the web browser. Refer to the potential fixes provided below to fix the problem.

Option 1 – Try to toggle the settings of the Internet Options

  • In the Windows Search box, search for Internet Options to open it.
  • Next, go to the Security tab and drag the security slider to the lowest possible security for all the given zones.
  • After that, click on OK to save the changes made and close the Internet Options.
Note that this option is only a temporary measure as it can make your computer vulnerable. Make sure to press the Reset all zones to default level button.

Option 2 – Try to update or reinstall the respective drivers

If updating the drivers of the device did not fix the problem with the USB security key, you can try to update or reinstall the Universal Serial Bus Controller drivers instead of using the Device Manager. Refer to the following steps:
  • First, click the Start button and type “device manager”.
  • Then click on the “Device Manager” from the search results to open it.
  • From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.
Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.
  • Restart your PC and then click the “Search automatically for updated driver software” option.
Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 3 – Try to change the PIN of the security key

If the first two options didn’t work, you can try changing the PIN of the security key. There are instances when the PIN for the security key might have been corrupted. Thus, resetting it can help you resolve the problem.

Option 4 – Temporarily disable Firewall and third-party antivirus

Firewall and antivirus programs are known to block the proper functioning of the USB security key. Thus, your antivirus or firewall programs might be the reason why you can’t download anything on your Windows 10 computer. To isolate the issue, you need to temporarily disable both the Firewall and antivirus programs and then check if you can now download anything from the internet. Do not forget to enable them again as disabling them can leave your computer vulnerable to cyber threats.

Option 5 – Try to troubleshoot the web browser

Troubleshooting your web browser can also help you fix the USB security key problem. You can do that by checking if your web browser supports the security key and you can do that by checking on the official website of your browser. You can also try to update your web browser to its latest version but if it didn’t help, you can try to reinstall it or switch to another web browser.

Reliability Monitor is not updating or working
In case you don’t know, there is a built-in tool in Windows 10, known as Reliability Monitor that provides a day-to-day snapshot of the health of your system. It warns users of any looming issues or disasters before your computer breaks down finally. So obviously, Reliability Monitor is useful, however, there are times when it could behave incorrectly. For instance, it might fail to show you any updates even when they are installed. Thus, if you experience any malfunctions with the Reliability Monitor tool in Windows 10, read on as this post will guide you in updating or working in Windows 10. To fix the problem with the Reliability Monitor, there are several fixes you can check out. You can try to enable the data collection for Reliability Monitor or reset it, as well as put your computer in a Clean Boot State. For more information, refer to each one of the options given below.

Option 1 – Try to enable the Data Collection for Reliability Monitor

The Reliability Monitor tool uses data provided by the RAC Agent scheduled task and it will start to display a Stability Index rating and specific event information 24 hours after the system installation. The RACAgent scheduled task, by default, runs after the operating system is installed. And if it is disabled, it must be manually enabled from the Task Scheduler snap-in for MMC or Microsoft Management Console. Thus, you need to enable the Data Collection for Reliability Monitor to fix the problem.

Option 2 – Try to reset the Reliability Monitor

The next thing you can do to fix the issue with the Reliability Monitor might want to reset it to resolve the problem. If the Reliability Monitor is already open, you have to close it and open it again. After the reset is done, it may take up to 24 hours for the Reliability Monitor to display results again. This should fix the problem.

Option 3 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Black border issue. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
  • From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Easy Remove PCPerformer From Windows

PC Performer is a registry cleaner made by PerformerSoft. The purpose of this program is to remove redundant items from the Windows registry. Registry cleaners remove broken links, missing references within the Windows registry. PC performer is designed to automatically optimize your registry and clean it up.

PC Performer adds registry entries for the current user that allow it to run automatically each time the system is rebooted. It adds a scheduled task to Windows Task Scheduler in order to run at various times. The software connects to the internet, therefore it creates a Windows Firewall exception that allows it to connect without interference. Multiple anti-virus programs detected this software as Malware, it typically comes bundled with other software or is distributed through a pay-per-install bundle.

About Potentially Unwanted Applications

People have encountered it – you download and install a piece of free software application, you then see some unwanted applications on your computer or discover a strange toolbar has been added to your browser. You didn’t install them, so how did they turn up? These unwanted programs, technically known as Potentially Unwanted Programs (PUPs), often come bundled along with other software and install themselves on user’s PC without their knowledge. They perhaps might not look like viruses to some individuals, but they can produce major annoyances and bring about serious trouble for users. The idea of PUP was coined to define this downloadable crapware as something other than malicious software. Much like malware, PUPs create problems when downloaded and placed on your computer, but what makes a PUP different is that you provide consent to download it – the fact is vastly different – the software installation bundle actually tricks you into agreeing to the installation. Still, there isn’t any doubt that PUPs are still bad news for computer users as they can be incredibly damaging to your computer in lots of ways.

What do PUPs look like?

The unwanted software programs after installation display loads of annoying pop-up adverts, create fake alerts, and quite often it even pushes the user to buy the software. Likewise, the majority of free software applications these days come with quite a few unwanted add-ons; in most cases a web browser toolbar or browser modification such as a homepage hijacker. Not only they needlessly use up space on your screen, but toolbars can also manipulate search engine results, watch your browsing activities, decrease your web browser’s performance, and decelerate your net connection to a crawl. PUPs employ aggressive distribution techniques to get in your computer. Some might include information gathering program code that could collect and send your private information back to third parties. Due to this unwanted program, your application may freeze, your security protections may get disabled that might leave the computer susceptible, your system may get ruined, and the list goes on and on.

Tips on how to prevent ‘crapware’

• Read cautiously before agreeing to the license agreement as it may have a clause about PUPs. • Usually, when setting up a program you will get two options, ‘Standard Installation (recommended)’ and ‘Custom Installation’. Don’t select ‘Standard’ as PUPs could be installed that way! • Use good anti-malware software. Try Safebytes Anti-Malware which will find PUPs and handle them as malware by flagging them for removal. • Be alert when you install freeware, open-source software, or shareware. Avoid downloading browser extensions and programs you are not familiar with. • Only download applications from the original providers’ sites. Avoid download portals as they use their own download manager to pack additional programs with the initial download.

What you can do if Virus Stops You From Downloading Or Installing Anything?

Malware could potentially cause several kinds of damage to computer systems, networks, and data. Certain malware goes to great lengths to stop you from installing anything on your PC, especially antivirus applications. If you’re reading this right now, you have perhaps recognized that a malware infection is a reason for your blocked web traffic. So what to do if you need to install an antivirus program like Safebytes? There are a few actions you can take to get around this problem.

Eliminate malware in Safe Mode

If the virus is set to load automatically when Microsoft Windows starts, getting into Safe Mode could very well block the attempt. Since just the bare minimum programs and services start-up in safe mode, there are hardly any reasons for issues to happen. The following are the steps you should follow to remove malware in Safemode. 1) At power on/start-up, hit the F8 key in 1-second intervals. This will bring up the Advanced Boot Options menu. 2) Select Safe Mode with Networking using arrow keys and hit ENTER. 3) Once you get into this mode, you should have an internet connection again. Now, obtain the malware removal application you need by using the browser. To install the software, follow the directions in the installation wizard. 4) After installation, do a complete scan and let the software delete the threats it detects.
