I am certain that I had one of the Sasser variations because I had the spontaneous count-down shut-down and reboot problem.  Also, I manually went in and found avserve2.exe and several windows/system32/#s_up.exe and deleted them.  That stopped my shut-down/reboot problem.  However, I have something reloading evertime I reboot located at C:Windows\System32\Drivers\etc\hosts.  If I try to access Symantec or McAfee webpages directly or by linking to them otherwise, I cannot do so.  But I then go in and delete the aforementioned HOSTS, then I am able to access those webpages.  However, this recurs evertime after I shut down then log back in and requires deleting each time.

I have now installed the Microsoft updates.  Also, I have ran the downloads for getting rid of Sasser put out by Microsoft, Symantec, and McAfee(Stringer), and they all say I'm clear.  But this remnant of a problem still exists.  Also, I showed clear on a Dos scan.  I have read alot about sasser over the past 76 hours, but I have not come across any mention of my problem.

I will greatly appreciate your guidance!
