Random freezing in a Windows in the middle of work can be a very frustrating experience and can even cost us the loss of work. From time delays to sometimes complete crashes this behavior is something that every PC user wants to avoid or at least have very little of. In this article, we will cover solutions on what to do and how to fix the random freezing of computers.

1. Run a virus scan on your computer.

   Viruses and other malware can cause freezes and other issues in your computer, run a complete system scan for any kind of viruses and malware and if needed remove them.

2. Uninstall applications that you are not using

   Besides taking your hard drive space some applications can have and require to have some services always running on your computer which can cause some issues, if an application is not needed and it is not used, removing it might solve freezing issues.

3. Increase RAM memory

   Sometimes the problem with freezing is not a software issue, having less RAM memory than the application requires can cause the application not to work properly and it can cause freezing of the entire system since precious RAM can not be allocated to the required application.

4. Run system checker

   Corrupted Windows system files can cause freezing of the entire system, to fix this, start the command prompt in administrator mode and type sfc /scannow

5. Keep running applications to a minimum

   Having too many applications running in the background can drain system resources and can cause system freezes because of lack of memory. Close applications that are running in the background and keep them minimal.

6. Delete files and folders which you are not using

   Having many files and/or folders on the hard drive can cause a lot of system resources to be wasted, from indexing size to less free space for caching. If you have files that you no longer need, removing them will free up space and can increase performance and introduce the stability.

7. Run memory check

   Memory issues could lead to system freezing. When an application needs to write or read to a corrupted memory cluster, freezing will occur since it can not. To check memory bring up run dialog and type in ti mdsched.exe, click on restart now and let the memory test finish.

8. Update all drivers

   Hardware issues can cause freezing of applications and having the latest drivers can make a world of difference. Make sure that you have all device drivers to the latest versions.

9. Optimize Disk drives and check for errors

   Windows 10 has built-in tools to check hard drives for errors and to optimize them, use them in order to see if this issue is causing freezes.

10. Clean your registry

    A Clean registry is a happy registry and Windows is appreciating it. Make sure that you do not have any keys which you do not need in the registry and that long-forgotten application trails are deleted for good.

11. Upgrade SSD firmware

    Like updating drivers, updating firmware is also important, and having the latest firmware for your SSD can help a lot, newer firmware can eliminate freezing if the issue was in Windows not using SSD properly.

12. Update BIOS

    Like updating SSD firmware can help so it can update Firmware on your BIOS. Make sure that you have the latest firmware version and freezing can go away if that was the issue.

FindYourMaps is a Google Chrome Browser Extension developed by Mindspark. This extension hijacks your home page and new tab page changing them to MyWebSearch.com in order to display ads more efficiently.

Several anti-virus applications have marked this Extension as a Browser Hijacker due to its data mining behaviors and ad injections and were marked for removal by most of them.

About Browser Hijackers

Browser hijacking is a very common type of internet fraud where your web browser configurations are modified to allow it to do things you never intend. Practically most browser hijackers are made for advertising or marketing purposes. These are typically used to force visitors to a specific website, manipulating web traffic to generate ad revenue. However, it is not that innocent. Your web safety is jeopardized and it is extremely annoying. What’s more, hijackers will make the whole infected system fragile – other harmful malware and viruses would use these opportunities to get into your system very easily.

Indications of browser hijack

There are many symptoms that indicate the browser is highjacked: your home page is reset to some unknown site; you observe new unwanted favorites or bookmarks added, typically directed to ad-filled or porn websites; The default search page of your web browser is modified; you see many toolbars on the browser; you observe numerous ads show up on the browsers or display screen; your browser has instability issues or displays frequent errors; you cannot go to specific sites such as home pages of security software.

How it infects your computer

A browser hijacker could be installed on your PC when you check out an infected website, click an e-mail attachment, or download something from a file-sharing website. They also come from add-on programs, also known as browser helper objects (BHO), web browser plug-ins, or toolbars. A browser hijacker could also come bundled up with some free application which you inadvertently download and install the browser hijack, compromising your PC security. Browser hijackers can record user keystrokes to gather potentially invaluable information leading to privacy concerns, cause instability on computers, drastically disrupt user’s browsing experience, and ultimately slow down the system to a point where it will become unusable.

How to fix a browser hijack

The one thing you can try to remove a browser hijacker is to locate the malware inside the “Add or Remove Programs” list of the Windows Control Panel. It may or may not be there. When it is, uninstall it. But, many hijacking codes aren’t very easy to remove manually, as they go much deeper into your operating system. On top of that, manual removal demands you to carry out several time-consuming and tricky procedures that are very hard to carry out for novice computer users. Anti-malware application is incredibly efficient when it comes to picking up and eliminating browser hijackers that standard anti-virus software has overlooked. Safebytes Anti-Malware features a state-of-the-art anti-malware engine to help you avoid browser hijacking in the first place, and clean up any pre-existing problems.

Steam Deck release is almost upon us and more news comes to light. The Latest officially confirmed technical detail is that the user will have access to device's BIOS and that dual booting will be officially supported. This, of course, means that you will be able to have both Proton and Windows on your device letting you play anything that you wish if the hardware is strong enough.

Microsoft has cut out Russia from downloading ISO files for Windows 10 and Windows 11 as well as installation tools without any explanation or reason behind this.

If you connect via VPN to a Russian server and try to download either ISO files or installation tools you will be greeted with the error 404 and an explanation of File or Directory not found or There was a problem with your request.

At this time you can still download Windows 11 Media creation tool but once you run it will throw a 0x80072F8F-0x20000 error with text: For some unknown reason, this tool failed to run on your computer.

People in Russia can still download files if they connect via VPN and go to a server located outside Russia.

Microsoft has not published any explanation why is this happening, it might be technical difficulty or it could be on purpose.

Other histories of Microsoft vs Russia

Since the beginning of the Russian military operation in Ukraine Microsoft has been putting restrictions on Russia starting with a suspension of all sales in March, next month in April Microsoft started suspending developer's accounts on GitHub linked to sanctioned companies and the suspension was even if the developer is not working for a given company or left it.

At the beginning of this month, Microsft laid off 400 employees inside Russia as they began scaling back operations in the country but has also stated that they would continue to provide services to all contractors and customers inside Russia so this sudden blocking of downloads is unexpected and it goes against their statement.
