Persistent Multiple Trojans

I've been scanning and removing in different forms for two days now; I've run through the normal virus removal steps described in your tutorial at least twice and looked up all the HijackThis entries in Sysinfo.org, as suggested. I certainly found a few bad files, including, smss.exe, alg.exe, csrss.exe, lsass.exe, etc. etc. The first time I found these, I was able to terminate the processes and "fix" them entries with HijackThis. However, they showed up again with a couple of new friends under the SYSTEM user, and if I try to terminate them now access is denied.

Symptoms, BTW, are your usual pop-ups, with the bonus that IE crashes everytime it is opened by the malware (or whatever this is).

The latest HT log is attached.

Thanks for any help.
