Besides modifying the atapi.sys driver it also sets up several files in Startup\Run\. I have several computers infected with this virus.
Files I've found are: siszyd32.exe (Startup\Run) and other similar files. Also, has hidden background processes or sometimes opens files like ~TMP.tmp or smth like that.
Sugessted was kaspersky virus removal tool which I'm using right now, and waiting for it to finish.

I have found the av_md.exe through the process explorer. I believe it sets up a new user account in svchost.exe 1048 on XP. This for me entailed the DCOM Server Process Launcher(system32\rpcss.dll) and Terminal Services (system32\termsrv.dll).
I believe that it will attach to a mail program on the computer and send out spam for "weightloss" products. Symantec stopped these from being sent.
Looking to remove it now.
