Michelle, I missed this one... was staring me in the face from your first log, but I knew combofix would remove it. Then of course I noted you were running Vista so combofix was not an option, and I forgot to put it in for fixing. It is still there, pls fix it, but note that its name will have changed!! So make a fresh hijackthis scan, look for [systemoptimizer]:

in first log:
O4 - HKCU\..\Run: [SystemOptimizer] rundll32.exe "C:\Users\michelle\AppData\Local\Temp\hrcybfat.dll",forkonce
...it became:
O4 - HKCU\..\Run: [SystemOptimizer] rundll32.exe "C:\Users\michelle\AppData\Local\Temp\xfmaawuu.dll",forkonce

So find it, fix it ..and delete this:

C:\Users\michelle\AppData\Local\Temp\whatever its new name is.dll

Sigh...

I dont see it maybe one of the 20 av programs I've been running 3x a day caught it lol.

As a matter of fact I'm pretty sure AvG grabbed that one this morning. I remember seeing that one on my HjT log and thinking it looked suspicious.

Good ole AVG. Ok, passed a keener eye over the log and it appears clean now.
Cheers.

Here's mud in your eye. Thanks again man. I keep telling myself to quit dating auto mechanics and get me a pc expert instead...lol.
