I did a full restauration 2 days ago as I had some major bugs.
After reformat and re installing key files & software I tried system restore, it would not restore. I booted in safe mode and did malware & virus searches.
I have xp family with service pack 3
I have Norton antivirus 2009 with enhanced autoprotection is this where the problem lies. Thank you
