Windows Antivirus System

Windows Antivirus System is a clone of similar rogue security applications that all share an identical interface and recycle the majority of their code. Like the other threats Windows Antivirus System resembles, Windows Antivirus System may be installed by Trojans that imitate Windows Security Essentials Alert windows. Windows Antivirus System will pretend to offer your PC security features, but none of the problems that Windows Antivirus System pretends to detect is real and none of Windows Antivirus System's positive features is functional. You may also experience other problems with unrelated applications while Windows Antivirus System is on your computer, particularly hijacks that redirect your browser to dangerous websites. To restore your computer's normal state of health, you should uninstall Windows Antivirus System by using an anti-virus or other security program to scan for and remove all Windows Antivirus System components.

The Trojan That Slams Windows Antivirus System Down on Your PC

Don't Fall for Windows Antivirus System's Fake Threat Bluffs

Windows Antivirus System doesn't try to break new ground with Windows Antivirus System's tactics and is content to use the same fake alerts that you can see on other threats. Some, but far from all of the errors you might see Windows Antivirus System create can include:

Of course, Windows Antivirus System hasn't any ability to detect or remove threats from your PC and you should never assume that any problem that's announced by Windows Antivirus System is genuine. Even cases where a program fails to start along with an infection alert are just symptoms of Windows Antivirus System blocking the program deliberately to restrict your access to PC security software.

Windows Antivirus System may also start whenever Windows launches and hijack your browser to control which websites you're able to visit. All of these attacks combined make it difficult to remove Windows Antivirus System, but the proper use of anti-virus software and Safe Mode should let you undo all of Windows Antivirus System's harmful system changes.
