ok after not using my computer for approx 2 mths + therefore not updating anything I used it again yesterday without updating 1st. Stupid I know. As I was surfing the net I got a prompt out of the blue from spybot asking if I wanted to allow a registry change but with the option to deny faded. I chose not to allow it and ignored it until I switched the computer off. I then updated all programs and tested to see if I had anything. Spybot detected Smitfraud-c but was unable to remove it even when checked immediately at startup and in safe mode. However adaware,ewido ,avg ,spysweeper don't detect anything. Firewall detects no outgoing program attempts. Question is: Is this a false positive by spybot or is there something potentially nasty lurking on the computer? BTW there have been no problems ie blue screen,error messages etc on my comp and I have read other threads pertaining to smitf. Thx for the help/comments!
