I have Win 98se . I came up with a worm that Norton didn't find ([email protected]) . I was able to rid the worm , but , when I went to do my maintenance I ran a thorough Scan Disk and it found no problems . When I went to De Frag is when I have trouble . De Frag stops and prompts me to run a Scan disk . I tried this many times with no results . Any Ideas ???
