Windows Functionality Checker Removal Guide

Do you know what Windows Functionality Checker is?

Windows Functionality Checker is a fake antivirus program that comes from the same nest of computer threats as Windows Protection Master, System Smart Security, Best Malware Protection and others. Windows Functionality Checker is designed to fit seamlessly into your operating system, making it look like a legitimate complementary part of your Windows. Unfortunately, Windows Functionality Checker only wants to rip you off, and while the rogue’s at it, it destroys your computer.

When Windows Functionality Checker gets into your system, it injects a subkey into the registry, allowing it to load every single time you turn on your computer. The rogue wastes no time it attacking you, and it launches a fake system scan, informing you about viruses and Trojans that are not really there. Things like Server-Telnet, Trojan-Dropper, Trojan-Proxy or Trojan-Malifinder do not exist in your computer, and they only appear in the Windows Functionality Checker’s result list, because the rogue wants to push you into purchasing a license of a program which cannot live up to its promises.

What is more, Windows Functionality Checker can block your executables saying that your programs are infected with malware and need to be closed before the infection spread any further. The rogue also does not allow you to open Windows Task Manager, because with the tool open, you would be able to determine the rogue’s processes and end them. On top of that, Windows Functionality Checker bombards you with fake security notification messages, that are terribly annoying and considerably slows down your computer:
