Remove "System Check" (Uninstall Guide)

System Check is malicious software posing as Windows system utility. Although, it may look like a real thing, it isn't! You are actually dealing with scareware and the newest TDL rootkit. Once installed, this fake system utility starts throwing lots of bogus error messages, blocks Task Manager and other programs (including antivirus software), hides all icons and program shortcuts. It does the same thing in safe mode too. As you can tell already, it's a nasty virus. In a previous writeup, we analyzed another rogue program called System Fix. It's pretty much the same type of infection. The two most important things to remember when removing this virus: do not purchase it and do not delete temporary Windows files stored in %Temp% folder using CCleaner or similar software.
