Av-scan-pc-tools.net is a name of new annoying browser hijacker that redirects web browser to (you could have already guessed it) av-scan-pc-tools.net. This website is created to advertise WinSpywareProtect as it was a legitimate anti-spyware program.

Av-scan-pc-tools.net imitates system scan and generously offers deleting malwares using Win Spyware Protect. The page is misleading as it only mimics computer scan and WinSpywareProtect is not actually capable of removing infections. If your web browser is hijacked by Av-scan-pc-tools, you should only be concerned about removing Av-scan-pc-tools.net. All the infections reported by Av-scan-pc-tools.net are fabricated.
