What Is Phishing And How Can You Protect Yourself From It?
Ever gotten an e-mail offer that seemed just a little bit too good to be true? Might’ve been a phishing attempt! These are everywhere and can come in many different forms.
So what’s phishing exactly, how can you detect it and how can you keep safe?
What is phishing?
Phishing (pronounced like fishing) is a type of cyberattack that tricks the user into trusting the source and revealing sensitive information. Fishing being the perfect analogy, the bait is a legitimate-looking site, e-mail or file and when you take a bite, your identity, banking information and much more can be revealed and stolen.

Some phishing attempts are incredibly obvious, others are super elaborate. Like with most types of malware, cybercriminals have become extremely well-versed in phishing and anyone can fall for it. To help you recognize and avoid it, we’ll take you through a couple of phishing types and give you tips on what to do if faced with them.
Phishing techniques
E-mail phishing
This is actually the most common type of phishing. A cybercriminal creates an e-mail containing stuff like attractive offers, legitimate-looking attachments or links and makes it appear as though it’s coming from a trusted source.

For example, it looks like it’s coming from your bank or your favorite retailer. The logo looks legit and the structure of the e-mail seems familiar, so you might get tricked into clicking on whatever clickable content is in it.
Unfortunately this exposes your device to malware that hands your data off to the hacker, who can decide what to do with it further.
SMS and social media phishing
Like the above example, you could be approached with lucrative offers or links via text messages or social media messages. Typically, the messages seem relevant to the user as they will be made to look like they’re related to apps or services you’re using.
Voice phishing
Voice phishing attacks are schemes that appear as though they’re coming from a credible number. Normally, you’ll get a call about something related to credit cards or taxes to get you into a state of worry, leading you to disclose personal information on the phone.
Spear phishing, whaling and BEC
Spear phishing normally targets specific individuals within a company who are likely to have access to sensitive data. Spear phishers spend time collecting information they can use to reach out to the individual looking as trustworthy as possible. They’ll typically lead with something relevant, for example mentioning an upcoming company event, and make a seemingly legitimate request.
Whaling is a more elaborate form of spear phishing, which targets people in even stronger positions such as executives or high-value individuals. The ultimate goal is to get them to transfer financial or other sensitive information that can be used to compromise the entire business.

BEC, or Business e-mail compromise, is a specific spear phishing technique carried out via e-mail. While there are many ways this is done, most commonly you’ll see instances where the phisher poses as a CEO or similar executive, or as a lower-level employee in specific positions (e.g. sales managers or financial controllers).
In the first situation, the impersonator reaches out to employees requesting them to transfer certain files or pay invoices. In the second situation, the phisher takes control of the employee’s e-mail account and sends false instructions to other employees in order to obtain data and information from them.
What can you do?
There are many ways you can be aware and spot a phishing attempt. Here are some tips:
Always check the sender’s address in your e-mails, even when they seem to come from a familiar source.
In any instance where payment information is requested, be very, very careful.
If you are receiving attachments you never asked for and definitely didn’t expect, better not click on them.
Beware of content that transmits a sense of urgency (sales deals, urgent updates to login credentials, etc.).
Bad spelling and grammar are usually a telltale sign of phishing.
Links that look shortened (e.g. Bit.ly) or just suspicious in general - if you have a bad feeling, do not click on them.
If you are receiving threats, you probably shouldn’t be clicking on anything in that message.
Always examine first-time senders in detail.
Block suspicious e-mail addresses, numbers and social media accounts.
If you are receiving a coupon for free stuff… You aren’t.
If you’re being asked to update your payment details by a service you use, such as Netflix, chances are it’s an impersonator.
Those are some of the ways to identify and prevent phishing attacks. However, sometimes phishers disguise themselves a little too well or a misclick happens and there you go - you’ve been exposed to malware.

This won’t happen if you invest in powerful protection software from the get-go, though. A good antivirus program like Bitdefender will keep you safe from becoming a victim of phishing scams. In fact, it will protect you from malicious attacks overall.
Be it your household or your business you’re concerned about, there are a bunch of different packages and options available, providing different kinds of cybersecurity services. That’s the only way you can ever really be sure you aren’t at risk of a digital attack.
Summary
Have you ever been targeted by phishers and didn’t know that’s what it was until you read this article? Many can relate. Protect yourself before it’s too late!
Both the DISKPART utility and the Disk Management are useful tools in Windows 10 that manage the disk space allocation, and so on. But these tools are not without errors as you could also encounter some when you run them. Recently, some users reported getting an error that says, “The selected disk is not a fixed MBR disk when trying to use the DISKPART utility”. Here’s the exact message of the error:
“The selected disk is not a fixed MBR disk. The ACTIVE command can only be used on fixed MBR disks.”
This kind of error only occurs when you try to activate a disk partition on a UEFI system partition. However, the command works only if your computer is based on BIOS/MBR. The UEFI method has no concept of the active partition and since you have a UEFI system, the disk type is GPT instead of MBR. To simply put it, your BIOS needs the MBR disk type while the UEFI needs the GPT disk type.
To fix the “The selected disk is not a fixed MBR disk when trying to use the DISKPART utility” error, there are various potential fixes you can try. You might have to disable Secure Boot, convert the disk to MBR or fix the Boot Manager. For more instructions, follow the options provided below.
Option 1 – Disable the Secure Boot in the BIOS
Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:
First, boot your computer into Windows 10.
Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
After that, go to the BIOS of your computer.
Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
Select the UEFI Firmware Settings which will take you to the BIOS.
From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
Save the changes made and exit. Afterward, your computer will reboot.
Option 2 – Try converting the disk to MBR
You can try to change the File System of the drive from GPT to MBR but before you do so, make sure that you create a backup copy of your data to an external drive. Once you have that covered, follow the steps below.
Create a bootable Windows 10 media and boot your computer from it.
Next, click on the “Repair your computer” option on the first Windows 10 installation setup window.
Afterward, select the operating system partition from the given options and click on Next.
Now select Command Prompt within the System Recovery options box and execute this command to initiate the Diskpart utility: diskpart
Then type either one of these commands to view the list of all the Disk connects or the partitions on those disks formed: list disk or list volume
After that, execute another one of these commands depending on the command you previously entered to select the disk or partition you want to select: select disk # or select volume #
Now execute this command to clean your drive: clean
Finally, execute this last command to convert the selected disk or partition as MBR: Convert MBR
Restart your computer and check if the error is fixed.
Option 3 – Try to fix the Boot Manager
You can start by booting into the installation environment for Windows 10 from an installation media.
After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
bootrec /FixMbr
bootrec /FixBoot
bootrec /RebuildBcd
Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed error code 0xc000014c.
Hello everyone and welcome to another tutorial on errortools.com, Windows itself when it is installed has a general idea about certain file types and how to open them, for example, image files would be opened with application photos, web links with the edge, etc. So when we double click on the known file type, Windows will start the default application for that type and open the file in it. But what if we do not want to open files in applications Microsoft thinks we should? What if we want to open the website in firefox or images in photoshop, or whatever.
Luckily we can easily change which application Windows uses for which file type.
Click on ⊞ WINDOWS to open the start menu and choose settings.On the settings screen, choose Apps.
When the Apps screen opens on the left click on Default apps.
On right, you will get a list of Windows default applications for certain types of files. Click on any application you would like to change and choose from the drop-down list a new one. Click on it and you are done.
One of the useful features that came with Windows 10 is the Mobile Hotspot although there’s a downside to it – it drains your battery faster especially if your Windows 10 device is running on battery. Another one of its flaws in the implementation of this feature is that it stays activated even when the connection is idle. In other words, it is still activated even if no devices are connected to it. As a result, it consumes battery life and affects it. There are also instances when it affects the performance of the network connection. At the time of writing, Microsoft hasn’t done anything about this dilemma yet so in the meantime, you can continue reading this post to resolve this issue on your Windows 10 device.
You can remedy this Mobile Hotspot issue by running a command in Windows PowerShell. To get started, follow the given instructions below.
Turn off Mobile Hotspot Automatically:
Step 1: The first thing you have to do is to copy the following command:
Step 2: After copying the command given above, open the Notepad app and paste the command you copied there and save it. And when saving it, select the “Save as” option and its File type as “All files”.
Step 3: After that, put “TurnOnTimer.bat” as the file’s name and save it on your Desktop.
Step 4: Once done, run the file you just created, and when a User Account Control or UAC prompt appears, just click on Yes.
Step 5: After you run the file, it will run a series of scripts in a command line which will turn off the Mobile Hotspot automatically when idle.
And that’s how you automatically turn off the Mobile Hotspot when your Windows 10 device is idle. On the other hand, if you want to undo the changes made, you can always do so using the steps provided below.
Turn on Mobile Hotspot:
Step 1: Copy and paste the following command in the Notepad app:
Step 2: After copying and pasting the command, save it as “TurnOffTimer.bat” on the Desktop.
Step 3: Once done, run the file like what you did earlier and select Yes when a UAC prompt pops up. This will run a series of scripts on a command line which will revert the changes back to their default state.
If you have received a BSOD error message that says, “Tcpip.sys”, read on as this post will show you how you can fix the problem. The “Tcpip.sys” means Transmission Control Protocol over Internet Protocol. It is a library of a set of rules that are used to interconnect different devices all over the internet. The Tcpip.sys file is a driver and if a BSOD error message includes this one, it could only mean that the driver file is corrupted or incompatible with your system or there are some conflicting programs installed in your computer.
To fix this error, you can try the following workarounds. Make sure to carefully follow each one of them.
Option 1 – Check for conflicting or incompatible programs by putting your PC in a Clean Boot state
As mentioned, the “tcpip.sys” BSOD error might be caused by some problematic programs that clash with your existing operating system. Several users reported that numerous programs that are supposedly designed to enhance computer performance are causing conflict in the system instead. 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” checkbox 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” checkbox.
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.)
After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:
From the “Start” menu, go to System Configuration.
After that, switch to the General tab and click the option for “Normal Startup”.
Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
Then find and click “Enable all” and if prompted, you have to confirm.
Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
Restart your PC when prompted.
Option 2 – Disabling Antivirus Software
There are cases when the “tcpip.sys” BSOD error is caused by the antivirus program installed in your computer that’s blocking some essential operations. Because of this, the operating system fails which throws up the BSOD error. As you know, the antivirus program is designed to protect the computer and monitor every action in the system. However, there are instances when the antivirus program gives false positives and shuts down some modules even if it’s harmless. So this could be the case for the “tcpip.sys” error. To verify if the problem is indeed caused by the antivirus program in your computer, you need to temporarily disable it. After you’ve disabled it, restart your PC and then check if the problem’s fixed or not.
Option 3 – Try to update all your Drivers
From time to time, drivers get corrupted or outdated so it’s no surprise that they conflict with the operating system and cause errors like the “tcpip.sys” BSOD error. To fix the problem, you need to update all your drivers especially the network driver since the “tcpip.sys” error is closely related to this driver. Follow the steps below to update your drivers.
Tap the Win + R keys to launch Run.
Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
Restart your PC.
Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it. After that, you could also check if there’s a new update of the game you’re getting the issue of the black bar.
These days, Google Chrome is definitely one of the most used browsers in the browser. Google has almost created a nearly perfect product that rarely experiences problems. However, a lot of users have reported an issue where some files they’re downloading or their downloads in their Google Chrome browsers are stuck at 100%. So if you are one of these users, read on as this post will guide you on what you can do to resolve the problem.
This kind of problem could be caused by several factors. It is possible that the file download process could be blocked by a third-party antivirus or it could be that the content-length header could be missing from the server. Aside from that, a Google Chrome extension could also be the culprit or it could be that the current installation of the browser could be corrupted. This kind of problem can get really annoying as the download process has already utilized system resources as well as take up your time. Thus, you need to fix the problem using several suggestions. You can try to clear the browser cache, disable the Chrome virus scan, whitelist the file on the third-party antivirus program, put your browser in Incognito mode and download the file again. On the other hand, you could also try to reset or reinstall the browser. For more details, follow the options provided below.
Option 1 – Try to clear browser cache and try downloading again
There are times when some data in the browser is conflicting with the loading of the website and triggers some problems like download getting stuck at 100%. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.
Open your Google Chrome browser.
After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
Now select every checkbox that you see and click on the Clear data button.
Then restart your Chrome browser and check if you can now complete the download again.
Option 2 – Try disabling Chrome virus scan
The next thing you can do to resolve the problem is to disable the Chrome virus scan. It is possible that the virus scan is the one that’s preventing the download to be completed, thus, try to disable it and see if it works.
Option 3 – Whitelist the file you’re downloading in your antivirus program
The download getting stuck might also be caused by your antivirus program which could be interfering it from running. To fix this, you have to whitelist dism.exe. How? Refer to these steps:
Open the Windows Defender Security Center from the system tray area.
Next, click the “Virus & threat protection” option and then open the “Virus and threat protection settings”.
After that, scroll down until you find the “Exclusions” and click on the “Add or remove exclusions” option.
Then click the plus button and select the type of exclusion you want to add and from the drop-down list, select Folder.
Next, navigate to this path and select the WinSxS folder: C:/Windows/WinSxS
When a User Account Control or UAC prompt, just click on Yes to proceed.
Option 4 – Try downloading the file in Incognito mode
There are certain browser extensions, especially those security programs, that prevent any suspicious files from being downloaded. So the easy way to fix the problem is to launch the Chrome browser in Incognito mode and then try to download the file again. Additionally, you might want to consider disabling the problematic extension.
Option 5 – Reset Chrome
Resetting Chrome can also help you fix the problem. This means that you will be restoring its default settings, disabling all the extensions, add-ons, and themes. Aside from that, the content settings will be reset as well and the cookies, cache, and site data will also be deleted. To reset Chrome, here’s what you have to do:
Open Google Chrome, then tap the Alt + F keys.
After that, click on Settings.
Next, scroll down until you see the Advanced option, once you see it, click on it.
After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
Now restart Google Chrome.
Option 6 – Try to clean reinstall Chrome
There are instances when programs leave files behind after you’ve uninstalled them and the same thing can happen to Chrome so before you reinstall Chrome, you have to make sure that you have deleted the User Data folder. To do so, refer to the following steps:
Hit the Win + R keys to open the Run dialog box.
Next, type “%LOCALAPPDATA%GoogleChromeUser Data” in the field and hit Enter to open the User Data folder.
From there, rename the default folder and name it something else, e.g. “Default.old”.
After that, install Google Chrome again and check if the issue is now fixed.
There are a lot of home users that often get a computer that comes installed with the Windows 10 Home.

Once a tedious and unfriendly task of installing fonts has been severely made easier and more user-friendly. As technology advances daily so do some tasks. One of these tasks which today look unnecessarily complicated is fonts installation in Windows. What was once complicated navigation to control panel with an administrative account, today is two-click with the mouse anywhere, well anywhere on your hard drive, but still a great improvement nonetheless.
Ok, so you have found cool new font which you like very much and you are eager to try it out, but how do you install it in Windows so your other software can find it and use it?
The task is incredibly easy, let's presume that you have downloaded desired font or fonts to your hard drive from the internet, they are nicely placed in a folder, all you have to do is select which one you would like to install, right-click on any one selected and click on install. That's it, that is all that you need to do.
Now in order to remove fonts first, you will have to go to the folder which has all fonts installed in the system. The location of this folder is conveniently enough c:\Windows\Fonts. In there select all fonts that you would like to uninstall from the system and simply delete them, that's it.
Quest 2 has been crowned as the best overall VR headset by many websites, and to be honest it is really a great piece of equipment deserving of every praise it gets. It seems that Meta feels that it can do better so the new upcoming Quest Pro is upgraded and a new line of VR sets from this company. The economic standard Quest line will not be shut down and it will still remain as an economic version of Meta's VR product line.
Quest Pro will be added as a new line of the better product line with better performance and better quality. It is the first VR headset that is packing Qualcomm Snapdragon XR3+ Gen 1 chipset, 12GB of RAM, 256GB of internal storage, and 10 high-resolution sensors.

It is common to run multiple programs and applications at the same time and it’s important to be able to switch between them using their Taskbar icons or using the usual Alt + Tab shortcut. However, there are times when you might suddenly find that neither of the aforementioned methods worked and you will no longer be able to switch between programs in the Windows Taskbar. To fix this issue, refer to the options given in this post.
For instance, when you have multiple instances of Microsoft Edge running and every time you press the Alt + Tab combo nothing happens so you are left with no choice but to minimize everything and then hover your mouse on the icon and switch between the instances of Edge. You will also notice that the right-click on the taskbar won’t respond back and will only keep on showing the loading circle icon.
Here are a few tips you can follow to fix the issue with the Windows 10 Taskbar.
Option 1 – Try to restart the Windows Explorer
This is one of the basic things you can try as restarting Windows Explorer helps in refreshing the user interface and makes most of the things work in relation to the user interface.

Once you find the explorer.exe, right-click on it and click Restart.
Option 2 – Try changing the Foreground Lock Time
Aside from restarting Windows Explorer, you could also try changing the Foreground Lock Time to fix the issue with the Taskbar.
Tap the Win + R keys to open the Run dialog box.
Then type in regedit in the field and tap Enter to open the Registry Editor.
Next, go to this registry key – HKEY_CURRENT_USERControl PanelDesktop
Next, change the ForegroundLockTimeout value from200000 to 0. After that, it will make sure that no other application will take away the focus from your current program or application. It could be that some other application has taken away the focus and even when you try to actually switch, the focus gets back to the old one. Anyhow, since you already changed the value of ForegroundLockTimeout, it will ensure that the focus is not switched.
Note: If you are running some Full-Screen applications there are some devices especially the gaming ones, disable the Windows key to make sure that you won’t be able to switch. If this is the case, you need to make some modifications to the Full-Screen games.
On the settings screen, choose Apps.
When the Apps screen opens on the left click on Default apps.
On right, you will get a list of Windows default applications for certain types of files. Click on any application you would like to change and choose from the drop-down list a new one. Click on it and you are done.
