The January version of Microsoft Windows Malicious Software Removal Tool, (MWMSRT) helpfully downloaded by Windows Update, ran and detected a virus. MWMSRT called this fellow "Trojan:Dos/Alureon.E" which is probably Microsoft speak for "It's a Trojan Horse, it doesn't run under any flavor of Windows so we will call it a DOS virus and Alureon.E is it's name.
MWMSRT claimed to have winged it but not killed it dead. MWMSRT recommended I run a regulation anti-virus to get rid of it.
So I did. I have two anti virus programs and I ran them both. Then I reran MWMSRT to make sure Alureon.E was good and dead. No such luck. The slippery little rascal was still in my system.
So I googled for him and turned up a lot of chit and chat. You have to be careful googling on viruses, cause all sorts of Internet slime will offer to fix it for you, just download their program. Avoid those.
There was no clear cut "how-to-kill" posting. There was a hint that Alureon.E hides out in a special 2 megabyte "disk partition".
So for Windows XP, open "Administrative Tools". On my machine "Start->Settings->ControlPanel" gets me there. On your machine it might be different.
Once inside Administrative Tools, click on "Computer Management". Inside Computer Management find "Storage" and under "Storage" click on "Disk Management".
Look at the "Volumes". There ought to be a big one with a name containing "C:" and perhaps second one with a name that corresponds to a disk drive that you recognize from Explorer.
Those are good guys.
The bad guy is a partition with no name and 2 megabyte size. That's where Alureon.E lurks.
Right click on him and delete him.
Presto, Alureon.E is toast and MWMSRT will run clean.
