Windows Work Checker

Posted: June 9, 2011

ScreenshotWindows Work Checker is a clone of other fake security programs and shares the looks and malicious behavior of threats like Windows Salvage System. Even though Windows Work Checker's appearance makes it look like a security and anti-virus program, Windows Work Checker's only working functions are related to controlling your web browser, creating fake infection alerts and limiting your access to unrelated programs. Since Windows Work Checker is not only not helpful, but actively harmful to your computer, you should be prepared to delete Windows Work Checker as soon as you see it on your PC.

Checking Up on Windows Work Checker's Credibility

At a first glance, Windows Work Checker looks like a trustworthy application – Windows Work Checker uses the Windows icon and looks like a genuine security-monitoring application. People who are familiar with threats like Windows Salvage System, Windows Custom Settings, Windows Necessary Firewall or Windows Risks Preventions; however, you will notice that Windows Work Checker uses an identical interface!

Windows Work Checker's lacks the ability to help your PC security in any way, but this doesn't prevent Windows Work Checker from pretending to grade broad security concepts like 'network security' and 'private data protection.' You don't need to be worried over the poor grades that Windows Work Checker gives you for these aspects of your computer, since Windows Work Checker is designed to make these categories look poor on every computer that it infects.

Windows Work Checker can also use fake pop-up errors to make it look like actual infections are teeming just beneath the surface of your PC's security, corrupting everything in sight. Typical Windows Work Checker fake warnings include:

System Security Warning
Attempt to modify register key entries is detected. Register entries analysis is recommended.

Warning!
Location: [application file path]
Viruses: Backdoor.Win32.Rbot

Warning!
Name: [application file name]
Name: [application file path]
Application that seems to be a key-logger is detected. System information security is at risk. It is recommended to enable the security mode and run total System scanning.

Warning! Database update failed!
Database update failed!
Outdated viruses databases are not effective and can't [sic] guarantee adequate protection and security for your PC!

System component corrupted!
System reboot error has occurred due to lsass.exe system process failure.
This may be caused by severe malware infections.
Automatic restore of lsass.exe backup copy completed.
The correct system performance can not be resumed without eliminating the cause of lsass.exe corruption.

These warnings can't detect real threats. The only reason Windows Work Checker creates them is to make you think that purchasing a Windows Work Checker activation key is a good idea, but this action will only waste money and make your credit card vulnerable to other fraudulent attacks. If you've purchased Windows Work Checker by mistake, have your credit card canceled and the charges revoked.

How to Kick Windows Work Checker Out of Your PC

Attempts to remove Windows Work Checker can be slowed down by Windows Work Checker's other behavior:

  • Windows Work Checker can hijack your web browser to redirect you away from websites that contain solutions that would help you delete Windows Work Checker. Hijacks can create fake errors to make it look like these websites aren't safe, as well as change your homepage and search engine results.
  • Windows Work Checker may also directly prevent you from using a range of programs on your PC, particularly security-related programs. Although Windows Work Checker may tell you that these programs are infected, they'll work perfectly after you delete Windows Work Checker.

Deleting Windows Work Checker should be done with the help of a good anti-malware application, since Windows Work Checker is often accompanied by Fake Microsoft Security Essentials Alert Trojans and other threats. A full system scan in Safe Mode will let you get rid of Windows Work Checker without any of the above attacks impeding your actions.
