DownSpeedTest is a Browser Toolbar Extension for Google Chrome that allows users to test their internet speed and convert files, however this speed test does not show proper values, nor even close.

Upon installation DownSpeedTest will replace your default New Tab page with its own Search Engine “MyWay.com” or “Search.MyWay.com”. This Search Engine camouflages itself as a “Enhanced Google Search Engine”, but all it does is allow more room for easier ad injection. In the background, this extension monitors user browsing behavior and records visited links, viewed products, clicked links and time spend on websites. This information is later used for Ad targeting.

While browsing the internet with this extension enabled you will experience additional ads, sponsored content, and even pop-up ads on some occasions. Due to its information mining behavior and aggressive ad placement, DownSpeedTest had been marked as a Browser Hijacker and it is recommended for removal.

About Browser Hijackers

Browser hijacking is a type of unwanted program, commonly a web browser add-on or extension, which causes modifications in the browser’s settings. There are lots of reasons why you may experience a browser hijack; but commercial, advertising and marketing are the major reasons for their creation. These are typically used to force hits to a specific site, manipulating web-traffic to generate ad-revenue. Even though it might appear naive, these tools are made by malicious people who always try to take full advantage of you, so that hackers could earn money from your naive and distraction. In a worst-case scenario, your browser could be hi-jacked to download malicious software that can do a lot of damage to your laptop or computer.

How one can know whether the browser is hijacked?

When your web browser is hijacked, the following might happen: your browser’s homepage has been reset to some unknown webpage; new bookmarks pointing to porn websites have been added to your bookmarks; the default browser configurations are modified and/or your default web engine is altered; you see unwanted new toolbars added; unstoppable flurries of pop-up ads show up on your computer screen; your browser gets slow, buggy, crashes regularly; you can’t navigate to specific internet pages, such as security software related websites.

How does a browser hijacker infect a computer?

Browser hijackers infect computers via malicious e-mail attachments, downloaded infected documents or by visiting infected internet sites. They can be included with toolbars, add-ons, BHO, plugins or browser extensions. Also, some freeware and shareware can put the hijacker in your PC through “bundling”. Browser hijackers could record user keystrokes to collect potentially important information leading to privacy concerns, cause instability on computers, significantly disrupt user’s browsing experience, and ultimately slow down the system to a point where it becomes unusable.

How you can fix a browser hijack

One thing you could try to eradicate a browser hijacker is to find the malware in the “Add or Remove Programs” list of the Microsoft Windows Control Panel. It might or might not be there. When it is, uninstall it. However, most browser hijackers are difficult to eliminate manually. Regardless of how much you attempt to get rid of it, it might come back over and over. Amateur PC users should never try for the manual form of removal methods, since it demands in-depth system knowledge to perform fixes on the system registry and HOSTS file. Anti-malware software is really effective when it comes to picking up and eliminating browser hijackers that regular anti-virus application has overlooked. If you’d like to get rid of persistent hijackers effectively, install the top-rated Anti-Malware software Safebytes Anti-Malware. Use a system optimizer (like Total System Care) along with your anti-malware software to fix various registry issues, remove system vulnerabilities, and improve your computer performance.

What To Do If You Cannot Install Any Anti-Malware?

To start the computer into Safe Mode, press the “F8” key on the keyboard just before the Windows logo screen shows up; Or after normal Windows boot up, run MSConfig, look over “Safe Boot” under the Boot tab, and then click Apply. Once you are in Safe Mode, you can try to install your antivirus application without the hindrance of the malicious software. Following installation, run the malware scanner to get rid of most standard infections.

Download the anti-malware program using a different browser

Web-based malware could be environment-specific, aiming for a particular web browser or attacking particular versions of the browser. If you’re not able to download the security program using Internet Explorer, it means virus is targeting IE’s vulnerabilities. Here, you should switch over to an alternative web browser such as Chrome or Firefox to download Safebytes Anti-malware software.

Install anti-malware on a thumb drive

Another solution is to save and operate antivirus software tool completely from a Pen drive. Follow these steps to use a USB flash drive to clean your infected PC. 1) Make use of another virus-free computer to download Safebytes Anti-Malware. 2) Insert the USB drive on the same system. 3) Double click on the downloaded file to run the installation wizard. 4) Choose the USB flash drive as the location for saving the software file. Follow the instructions to complete the installation process. 5) Now, plug the USB drive into the corrupted computer. 6) Double-click the Safebytes Anti-malware icon on the pen drive to run the application. 7) Run Full System Scan to identify and clean-up of all types of malware.

Technical Details and Manual Removal (Advanced Users)

To get rid of DownSpeedTest manually, go to the Add or Remove programs list in the Control Panel and select the offending program you want to get rid of. For internet browser extensions, go to your browser’s Addon/Extension manager and choose the plug-in you intend to disable or remove. You’ll likely also want to reset your web browser. To ensure the complete removal, manually check your hard disk and computer registry for all the following and remove or reset the values as needed. Please be aware that this is for skilled users only and might be challenging, with incorrect file removal causing additional system errors. In addition, some malware is capable of replicating itself or preventing deletion. You’re suggested to do this procedure in Safe Mode.

Upgrading your Windows computer may not always go as expected as you could end up getting some error messages along the way. One of the error messages you can encounter is the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. This error indicates that is some security issue within the Windows operating system. It could be that the system files have an issue and they have been modified incorrectly. Although this does not necessarily mean that malware is behind the modification, one of the applications you installed recently might have something to do with the problem. The application might have modified or corrupted some of the core system files. When you encounter this error, you will see a blue screen along with the following error message:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete) If you’d like to know more, you can search online later for this error: 0xc000021a”

This error pops up when a user-mode subsystem like the WinLogon or the Client Server Run-Time Subsystem or CSRSS has been compromised fatally and security can no longer be guaranteed in the system. Thus, the operating system switches to kernel mode, and Windows won’t be able to run without the WinLogon or the Client Server Run-Time Subsystem. This is why it’s one of the few cases where the failure of a user-mode service can shut down the system. To resolve the issue, here are some fixes that might help.

Option 1 – Uninstall programs you installed lately

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 2 – Perform System Restore

Performing System Restore can also help you fix the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 3 – Run the System File Checker or SFC scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the cause why you’re getting the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Rebuild the BCD and fix MBR

Rebuilding the BCD can help you in fixing the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error.

• 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.
• Next, select Command Prompt and type in the commands below one by one, and tap Enter right after you do so.
• exe /FixMbr
• exe /FixBoot
  • exe /RebuildBcd

The commands you entered should rebuild the BCD and repair MBR.

Option 5 – Run the CHKDSK utility

You can also run the Chkdsk utility to resolve the problem. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them.
• chkntfs /t
• chkntfs /t:10

In Windows 11 by default inside the Start menu, there is recommended section that contains recently opened folders, documents, and files. If you do not wish this section and do not want recent items in your Start menu there is an easy way to turn it off.

1. Press ⊞ WINDOWS + I to open settings
2. Click on Personalization
3. On the right side scroll down and click on Start
4. Click on the switch beside Show recently opened items in Start, Jump lists, and File Explorer
5. Close settings

Windows photo viewer was a popular photo viewing application integrated into Windows 7, 8, and 8.1 but in Windows 10 it has been replaced with photos, Microsoft's new application aimed at photo viewing on your desktop. Now if any one of you wonders why should be bringing the old application back to Windows 10 since we have an alternative one, the answer would be resources and speed. The old photo viewer application is lightweight, fast, and reliable, opening the same photo in both photo viewer and in new photos shows us that Microsofts new viewer application takes even three times more RAM, and it's visibly slower in loading times for pictures. Since I am a person who prefers speed and functionality over fancy looks I would be very glad to have the option to bring back a photo viewer. If you have by any chance Windows 10 as an upgrade, bringing back photo viewer is easy as 1,2,3. you just need to open settings and go to default apps, under photo viewer you should see your current default viewing application, probably photos, click on it to see options and choose photo viewer and exit the Settings menu, and you're done. Sadly if Windows 10 has been installed clean on the system and not as upgrade things are a little bit more complicated but do not worry, stay with us, keep reading and you will get there.

Activating photo viewer

How technically photo viewer is still in the system but not used we will have to make it available again and this we will do by adding some lines in the Windows registry, that being said, open a notepad and paste the following code as it is in it.

Yup, that is a lot of keys and settings but you are almost done. Once you have pasted text into your new notepad document save it but as .REG, you can name it however you want but it has to be .REG extension. Once the file is saved double click on it to merge it into the Windows registry. You might need to turn off UAC for this operation (check our tutorial on this topic) and accept warning messages but once it is done you should now have an old photo viewer as a choice for your default viewing application. All you have to do now is to go to settings and go to default apps, under photo viewer you should see your current default viewing application, probably photos, click on it to see options and choose photo viewer and exit the Settings menu, and you're done.

What is PyLocky ransomware? And how does it execute its attack?

PyLocky ransomware is a file-locking malware created in order to lock important files and demand ransom from victims in exchange for data recovery. This new ransomware uses the .lockymap extension in marking the files it encrypts. It starts to execute its attack by dropping the following malicious payload in the system:

Name: facture_4739149_08.26.2018.exe SHA256:8655f8599b0892d55efc13fea404b520858d01812251b1d25dcf0afb4684dce9 Size: 5.3 MB

After dropping its malicious payload, this crypto-malware connects the infected computer to a remote server where it downloads more malicious files and places them on system folders. It then applies a data gathering module used to gather data about the user and the computer. The malicious files that were downloaded earlier along with the data obtained are used for another module called stealth protection. This allows PyLocky ransomware to execute its attack without detection from any security or antivirus programs installed in the system. It also modifies some registry keys and entries in the Windows Registry such as:

• HKEY_CURRENT_USERControl PanelDesktop
• HKEY_USERS.DEFAULTControl PanelDesktop
• HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun
• HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
• HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunOnce
• HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRunOnce

Once all the modifications are carried out, PyLocky ransomware will begin encrypting its targeted files using a sophisticated encryption cipher. Following the encryption, it adds the .lockymap extension to each one of the encrypted files and releases a ransom note named “LOCKY-README.txt” which contains the following content:

“Please be advised: All your files, pictures document and data has been encrypted with Military Grade Encryption RSA ABS-256. Your information is not lost. But Encrypted. In order for you to restore your files, you have to purchase a Decrypter. Follow these steps to restore your files. 1* Download the Tor Browser. ( Just type in google “Download Tor“ 2‘ Browse to URL: http://4wcgqlckaazungm.onion/index.php 3* Purchase the Decryptor to restore your files. It is very simple. If you don’t believe that we can restore your files, then you can restore 1 file of image format for free. Be aware the time is ticking. Price will be doubled every 96 hours so use it wisely. Your unique ID : CAUTION: Please do not try to modify or delete any encrypted file as it will be hard to restore it. SUPPORT: You can contact support to help decrypt your files for you. Click on support at http://4wcgqlckaazungm.onion/index.php”

How does PyLocky ransomware spread over the web?

PyLocky ransomware spreads using malicious spam email campaigns. Creators of this threat embed an infected attachment to spam emails and send them using a spambot. Crooks may even use deceptive tactics to trick you into opening the malware-laden immediately which is something you must not do. Thus, before opening any emails, make sure that you’ve thoroughly checked them. To successfully obliterate PyLocky ransomware from your computer, refer to the removal guide laid out below.

• Step 1: Launch the Task Manager by simply tapping Ctrl + Shift + Esc keys on your keyboard.
• Step 2: Under the Task Manager, go to the Processes tab and look for the process named facture_4739149_08.26.2018.exe and any suspicious-looking process which takes up most of your CPU’s resources and is most likely related to PyLocky ransomware.
• Step 3: After that, close the Task Manager.
• Step 4: Tap Win + R, type in appwiz.cpl and click OK or tap Enter to open Control Panel’s list of installed programs.
• Step 5: Under the list of installed programs, look for PyLocky ransomware or anything similar, and then uninstall it.
• Step 6: Next, close the Control Panel and tap Win + E keys to launch File Explorer.
• Step 7: Navigate to the following locations below and look for PyLocky ransomware’s malicious components such as facture_4739149_08.26.2018.exe and LOCKY-README.txt as well as other suspicious files, then delete all of them.

%TEMP% %WINDIR%System32Tasks %APPDATA%MicrosoftWindowsTemplates %USERPROFILE%Downloads %USERPROFILE%Desktop

• Step 8: Close the File Explorer.
• Step 9: Tap Win + R to open Run and then type in Regedit in the field and tap enter to pull up Windows Registry.
• Step 10: Navigate to the following path:

HKEY_CURRENT_USERControl PanelDesktop HKEY_USERS.DEFAULTControl PanelDesktop HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunOnce HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRunOnce

• Step 11: Delete the registry keys and sub-keys created by PyLocky ransomware.
• Step 12: Close the Registry Editor and empty the Recycle Bin.

Try to recover your encrypted files using the Shadow Volume copies Restoring your encrypted files using Windows Previous Versions feature will only be effective if PyLocky ransomware hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot. To restore the encrypted file, right-click on it and select Properties, a new window will pop up, then proceed to Previous Versions. It will load the file’s previous version before it was modified. After it loads, select any of the previous versions displayed on the list like the one in the illustration below. And then click the Restore button.

Things have stirred lately with Chinas ban on crypto mining and many used GPUs will flow the market probably. But should you buy a used GPU? Short answer: NO, long answer: keep on reading to find out why.

GPU shortage and its cause

As you all know by now, we live sadly in a world struck by a global Pandemic. Due to this awful disease and measures taken against it, many people are either working from home or are at home making the manufacturing of new chips problematic while demand on the market has raised. Throw into that mix crypto mining which has raised in popularity and you have, well today's market where we have GPU shortage. Now with the latest news that China has banned the mining of cryptocurrency, there is to be expected that at some point in time mining cards used there will fit the market in the whole world. Sadly even with a large quantity of GPUs that will become available, the overall price of cards will not be much lowered I am afraid since demand is still very high and many people would not want to purchase used mining cards and neither should you.

Be prepared for the worst scenario

Although this sounds very pessimistic and in most cases, it will not turn out to be true, you should always prepare yourself mentally that you might be in that lower percentage that will end up with a really bad GPU. What has come up to be absolutely true when considering GPU that were mining is that if anything at all can be done to GPU in order to increase performance, it has been done. Miners want to optimize and almost every GPU if could be overclocked, it was overclocked. Extensive mining also means that thermal paste has been dried and it is pretty useless at this point and there is a very high chance that fans and heat sinks will need much cleaning or even replacement raising the price of the card itself for mentioned paste, fans, and heat sinks. There's no way to tell what the previous owner might have done with a graphics card when you're shopping online, so our advice is to assume the worst. Don't trust the seller to give truthful information. Any listing that says it was "never used for mining" at this point is probably a lie.

Age of the GPU matters

Date when GPU itself has manufactured really matters. Newer cards even if used extensively have been used for a much shorter period of time and are not so damaged were ones produced a few years ago have seen a lot of action. Let’s say that you get RTX 3060, In the worst-case scenario it has been mining since late February of 2021 and basically, it is still under warranty so it should behave OK and put some good work in gaming even in that state. On another hand, if we take for example GTX 1080Ti which is 4 years old GPU things start to change drastically. 4 years GPU could be worn out even if it was used just for extensive gaming sessions let alone for mining.

No return policy and seller rating

Most of the time you will run into a product that cannot be returned or no refunds policy. This should bring a red flag right away and deter you from purchase. Sellers with the highest ratings are more trustworthy since many of them will not want to destroy their reputation but these will probably not even have these kinds of merchandise in their store. Buying with a poor rating seller and no return policy on a product is just asking for trouble. And although some stores do have arbitration and will stand on the customer side there is no guarantee for that and it will take too much time to process.

If you really must buy a second-hand GPU

Of course in these troubled times sometimes due to malfunction or any other reason, there would not be another choice than to buy a second-hand GPU. In this case, if there is no other option consider sellers with many positive ratings. If you can buy locally that would even be better or the best-case scenario would be if you could visually see and inspect GPU itself in order to see in what state it is. Look for warranty stickers to see if they are thorn and the card has been tampered with. Also take a good look at screws, if they have scratches card has been opened, probably to replace fan or heating sinks which means that it has worked a lot.

Conclusion

It is very difficult to give the best possible advice on this situation since of GPU shortage, but I would much prefer a new GPU with lower performance than a hi-performance one which was mining.

In case you don’t know, the .Net Framework is a programming infrastructure introduced by Microsoft. You will need it to run on lots of services and applications. Note that most of the applications that require the .Net Framework are packed with their installation files which is why it will be installed automatically on your computer when you install an application. However, there are instances when you’ll get an error message saying, “The .NET Framework 4.7 is not supported on this operating system” while trying to install the .NET Framework as a standalone service. The very reason why this error message appears is stated in the error message itself. Although the .Net Framework is supported on Windows 10, it is not actually compatible with some other Windows 10 versions. So it is most likely that you are seeing this error message because the .Net Framework in your computer is not compatible with the Windows 10 version you are running. Since that’s the case, you need to update Windows 10 to fix the problem. Updating your Windows 10 computer is the only solution you can try to fix this problem. Thus, it is advised that you check for Windows Updates even if you are now using the latest version of Windows 10. And since the issue is caused by an incompatible operating system version, once you install the exact version of Windows 10 required by the .Net Framework, the problem will be fixed. Simply follow the steps given below to do so.

• Step 1: Tap the Win + R keys to open the Run dialog box.
• Step 2: After that, type in “winver” in the field and tap Enter.
• Step 3: Next, your Windows 10 version should be given in the new window that appears. Take note that the number after the Version which is in the second line is your version number of Windows 10. And that the number must be 1507 or 1709. The first two digits in these numbers are the year while the second two represent the month when the update was released. So if you are running a 1709 version, this means that the Windows 10 version you are using was released in September 2017.
• Step 4: The next thing you have to do is to make sure that you have the Windows 10 version that’s compatible with the .Net Framework. To verify, you need to click here and click on the System Requirements.

After opening the link, take a look at the Supported Operating System section where it says, “Windows 10 Anniversary Update” and “Windows 10 Creators Update”. Since there are users who are not familiar with the version numbers related to both the Anniversary and Creators updates, refer to the list given below.

• November Update (1511)
• Anniversary Update (14393)
• Creators Update (1703)
• Fall Creators Update (1709)
• Spring Creators Update (1803)

As you can see, the Creators Update has version 1703 while the Anniversary Update has version number 14393 so if you are using a version lower than the 14393 version then it’s no wonder you aren’t able to install the .Net Framework 4.7 on your Windows 10 PC. Now all that’s left to do is to update your Windows 10 version and make sure that you will be updating it to the latest version available and then try installing the .Net Framework again.
