My son's laptop also on my McAfee account has had a box appear that says "Win 7 Total Security 2011" I'm aware this is malware and it won't let him access the internet to get Virtual Tech help.
Any help appreciated

Fake anti-malware isn't usually detected by any of the antivirus applications on the market as it relies on someone clixcking on it to activate it.
