I've had Norton Internet Security 2010 on the machine from the start however I still suspect there might be a problem. There's a very anomalous subdirectory that I can't delete from either my normal login or even the administrator login:
Volume in drive C is Local Disk
Volume Serial Number is C8CF-820B
Directory of C:\downloads
05/15/2010 10:59 AM <DIR> vlc
0 File(s) 0 bytes
1 Dir(s) 162,743,345,152 bytes free
C:\downloads>ls -l vlc
-rw-r----- 1 ???????? ???????? 0 2006-11-30 16:00 vlc
Disallow the Fast IO path for this operation.
I do find that I can delete vlc from Safe Mode however when I reboot into normal Windows, vlc is there again and I can't delete it.
Downloaded and installed Hijackthis. Ran Scan and it gives me a set of results.
Click 'Analyze this' which goes off and thinks about it. Analyze this then returns but it hasn't popped up a web page of results. Firefox is my default browser.
Any ideas as to what gives?
