how dangerous is it and what damage can it do to my system ? I can find much info on it
thanks for the prompt reply

Do I have to disable the Win XP SP2 “system restore” at all ?
I will do the boot time scanning as suggested . I am doing a “thorough scan” of my system (slider all to the right in simple interface) and also checking compressed files. I deleted the infected files from within the folder titled “infected” in the Advanced User Interface , they weren’t system files
