Can anyone help please. I am trying to get my sister's laptop running properly Win XP with SP2. I have run Ad-aware and AVG free edition which found lots of vurus's and Trojan Horses. Removed these then ran disk fixer on Ontrack's System Suite. This is telling me Disk Fixer found problem and to run DSKCHK /F. Have tried this but problem still remains. DSKCHK says that the disk has been verified at the three stages it runs, but it doesn'y actually say it has fixed them. Am I doing something wrong?
