Thanks! I downloaded the File Monitor (FileMon) from SysInternals site to see what this VB form (a virus in disguise) was doing. It is actually an EXE called msmdsrv.exe.1024 (and this number keeps changing) that's inside C:\Program Files\Microsoft Analysis Service (huh!)\Bin\. Here it writes to an MDB file called msmdqlog.mdb. It keeps opening and reading files and writing something after every few files to this database.

What do I do? How do I find the anti-virus for this? I already have McAfee running on my system and also NetSheild. What do I download from where to fix this?
