What is Webguard?

Developed by Interesting Solutions, Webguard is a tool supposedly used for tracking those online who’ve developed a habit of tracking you. The application would provide logical analysis into a user’s website history, providing insight on what websites you’ve visited and also how persons are able to track your every move while browsing. While Webguard is unable to dispose of who specifically is tracking your computer usage, they’re able to determine what computer installed tracking codes or cookies on your computer system. In this case, it’s then left up to the user’s discretion to determine who they want to allow or block from tracking their online use.  Overall, this application allows the user some measure of freedom and control over their online experience. Like any other application, however, which has landed themselves a spot on Virus Total, Web guard has hidden agendas. At a distance, Webguard installs a service for Windows but later distributes advertisements. Technical details about Webguard include:

Product Version: 1.0.0.0 Original File Name: crss.exe Entry Point:  0x000C5AAE

Assessment of Webguard Potentially Unwanted Program

While Webguard claims to track your computer usage, information reported by the application isn’t sufficient for the common computer user. This brings us back to the ulterior motive or principal objective of developing Webguard – to advertise and generate revenue from clicks made by users on Ads displayed on Internet Browsers – namely Chrome, Internet Explorer and Firefox. Why should a computer user remove Webguard? Simply, it compromises one's Internet privacy and security and it keeps abreast of your Internet history. If you’re online for an extended period, you’ll see what Webguard does. While the publishers behind the application did not alert users to the use of web beacons, cookies for tracking, and other related tracking technology, that’s not why Webguard is considered unwanted. The program is potentially unwanted because of the unpredictable advertisements it displays. Not all sites are trusted and so it’s difficult to determine, in some cases, what websites are legit for business.

Remove Webguard with Spyhunter

In most cases, at least from what I’ve seen, Webguard is installed as a single application. After it was installed for this assessment, it could be found in ‘All Programs”. This meant that one could manually delete the application from their computer system (see manual steps below). However, is that really sufficient to completely rid your PC of Webguard’s blueprints? While you might opt to remove Webguard manually – maybe because it’s more economical – an automated process is able to completely eradicate hidden threats from Webguard. In comparison to manually removing Webguard, Spyhunter penetrates your computer system for all infections. In most cases, nasty threats are unable to be removed manually. Additionally, Spyhunter not only removes installed threats, but it detects incoming ones – hence, acting as a preventative tool. Furthermore, Spyhunter detects cookies placed on your computer by Webguard. These are all undetectable threats and so an automated tool, as Spyhunter, should be used to remove Spyhunter effectively from your computer.

Manual Steps for Removal of Webguard

I found this removal pretty simple. Depending on your Operating System, there will be slight discrepancies in the manual removal steps. Using the Windows 8 (8.1) OS on your computer:

• Step 1: Locate the CONTROL PANEL on your computer using the SEARCH option.
• Step 2: Once the search box appears , input 'CONTROL PANEL'.
• Step 3: The Control Panel option will then appear. From the menu, choose the "Programs" option.
• Step 4: Another menu will appear. Select "All Programs and Features".
• Step 5: From the 'Programs list', search for the Webguard application.
• Step 6: Right-click on Webguard when it's found.
• Step 7:  Choose the "Uninstall" option.
• Step 8:  Follow the uninstall wizard instructions until the Webguard application is fully removed.

In this post, you will be guided on what to do if the Recent Items are no longer visible in the Taskbar icons in Windows 10. This can be quite inconvenient especially if you work simultaneously on many files and documents together and would require you to visit them regularly to incorporate changes. Thus, if you find that the Recent items are not visible in the Windows Taskbar, read on. In order for the Recent Items to appear on the taskbar icons in Windows 10 again, there are four potential fixes you can check out. You can try to show the recently opened items via Settings or clear the cache of the recent items. You could also make some changes in the Windows Registry or use the Group Policy Editor. But before you proceed with these potential fixes, it’s best if you create a System Restore Point first just in case something goes wrong after you made changes in the system. The System Restore Point allows you to undo these changes and bring back the previous state of your computer. Thus, you need to create one and then carefully follow the given options below.

Option 1 – Show the recently opened items via Settings

The first thing you can do to fix the problem is to show the recently opened items through the Settings app.

• Open the Settings app and select Personalization.
• From there, select the Start option and scroll down until you see the “Show recently opened items in Jump Lists on Start or the taskbar” option.
• Make sure that its toggle button is turned on.

Option 2 – Try to clear the Recent Items cache

• Tap the Win + E keys to open File Explorer.
• Next, copy and paste this link on the address bar: %AppData%Microsoftwindowsrecentautomaticdestinations
• Once you’re in the given location, you should see multiple files. Now select all these files and completely delete them.

Note: These files are automatically recreated when you interact with the system like performing tasks such as opening apps or accessing files.

• After that, go to this next location: %AppData%Microsoftwindowsrecentcustomdestinations
• Once there, delete all of its files and restart your computer. This should resolve the problem.

Option 3 – Try making changes via Registry Editor

The next thing you can do to fix the problem is to apply some tweaks in the Registry by following these steps:

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry sub-path: HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersion
• From there, select the Policies Explorer folder located in the left pane.
• Then move to the right pane and look for the “NoRecentDocsHistory” entry and right-click on it.
• Now delete this entry.

Note: This entry is the one that stores the Group Policy setting for “Do not keep the history of recently opened documents. The Group Policy adds this entry to the registry with a value of 1 if you enable the “Do not keep the history of recently opened documents” policy. On the other hand, if you disable the policy by setting it to “Not configured” or deleting it, the Group Policy will delete the entry from the registry, and the system will act as though the value is 0 – for instance, it keeps the history of the recently opened files in your computer.

Option 4 – Try to use the Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to launch the Group Policy Editor.
• Next, navigate to User Configuration > Administrative Templates > Start Menu and Taskbar.
• Afterward, double click on the “Do not keep a history of recently opened documents” policy located on the right panel. This is the policy that lets you enable or disable recent items and frequent places.
• Now to enable the recent items, as well as the frequent places, feature, click on the “Disabled” or the “Not Configured” option.
• Once you’re done, close the Group Policy Editor and restart your PC.

Note: If you choose to enable this setting, the system and Windows programs will not create shortcuts to documents opened while the setting is in effect. Aside from that, they also stay but won’t display the existing document shortcuts and the system will empty the Recent Items menu on the Start menu and the Windows programs won’t also display shortcuts in the Start Menu. In addition, the Taskbar won’t also show the recently opened or frequently used folders, files, or websites.

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.

Disk write permissions could also cause this error because if by any chance the Steam library folder has been set or changed to the read-only client would be unable to write anything in it. To easily solve this issue completely exit the Steam client and rerun it as administrator. Just right-click on it and select Run as Administrator. If this has solved your issue run Steam always as an administrator.

To run always as an administrator right click on the steam executable, go to properties, and inside properties go to the compatibility tab. In the compatibility tab check run as administrator and click on OK.

Clear download cache

If for any reason cache has become corrupted there is a big chance that this might be an issue why there is a disk drive error in Steam. To clear download, cache goes into your client, and on top drow down menu click on steam. Find and open settings and inside go to the downloads tab. Locate a clear download cache and immediately you will be prompted to restart Steam. After restart, you will be asked to login into steam and the issue with disk write should be gone.

Repair library folder
