Windows Scan Malware

NIS 2011

 

Hi, I just had this nasty little critter sneak in past the Firewall. The first time I noticed it was when trying to start a game and got its sneaky little message. I smelled a rat and after cancelling its offer to "defragment" my drive I then noticed a new shortcut on the desktop which I saw pointed to C: ~ Program Data\. The naughty thing wouldn't let me relaunch Firefox (to Google for help with removal) so I was forced to reboot in Safe Mode and delete all file bearing todays date in C: ~ Program Data\.

 

Now I'm darn sure I didn't accidentally click any installation options at the dodgy website I think this beast came from, so how come it got by Norton?
