if it is in system restore jut turn it off and back on again. I would not bother with it anyway it does nothing but hog amazing ammounts of hd room and never works! Iv tryed it countless times and it never does anything. If it is in a archive such as a zip or a cab file you may have more problems an the freebs arnt usualy able to remove from zips hence the paid for version of it. If it is lerking somewhere on you windows directory then you will have to find the exact name of the file and go to processes in control pannel and kill its process befor removal as you cant delete a file that is in use. I would suggest using kaspersky ativirus pro at about £40. True you never hear much of it but out of all the av iv tryed this is the best by miles with updates every few hours! Dont beleve the ppl in pc world and such places about the wounders if norton. Trust me it is micky mouse compared to kaspersky!
