If you are seeing the Windows Stability Center (see below) on your PC, then you are victim of malware attack that is trying to trick you into buying the full version of the program to remove bogus system threats. Do not fall for this scam and read further for removal instructions. If you are seeing this, your computer is infected.
The reason I am bringing this to your attention is that this past week the the so-called LizaMoon “SQL injection attack” began that redirects users by exploiting web site programming errors and poorly written website code and scripts. In other words at the redirected site, users will see a warning dialog that they had been infected with malware and a link to download a fake antivirus. I know none of this makes sense to you, but a massive internet attack has occurred that is trying to scare computer users into visiting a bogus antivirus site that has infected more than an half million websites and continues to spread, according to the Internet security firm websense.
