One machine I'm responsible for has all the signs of infection, but I have been unable to detect what the infector is with GMER, MalwareBytes, Rootkit Revealer and a couple of other tools. The company is running McAfee Virusscan Enterprise 8.7i with AntiSpyware module enabled. McAfee is fat, dumb and happy and thinks all is well.

Initially the user was experiencing browser redirects to advertisement pages. I found one entry in HKLM/Software/Microsoft/Windows/CurrentVersion/Run that was launching an executable from a temp file. Deleted that and the browser redirects seem to have stopped. Ran CCLeaner and OldTimer's Temp File remover and got rid of all the temp files, which didn't hurt either.

At present however the system still seems to be hosting an infector of some sort. The user is getting intermittent popups of the Microsoft JustInTime Debugger asking to debug a script which some process is trying to run under svchost.exe. I can usually see which svchost process is running the infector and can manually kill the process, but it's back after reboot.

Running netstat -a periodically shows normal expected connections at first bootup, but after a few minutes, outbound connections are made to numerous Internet hosts even though no browser or other application is running. Did ARIN lookups on some of the outbound IPs; they are all over the place (Colorado, New Jersey, overseas).
Hosts file has no redirects in it, however I took some of the outbound host names and redirected them to the loopback address to kill some of the connections, but the beastie seems to have more nodes in its database than I have the ability to redirect and kill that way.

Attempting to boot into Safe Mode results in a BSOD. I replaced the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot registry key from a known good machine, to no avail.

I'm no malware expert, but I've been in IT a good long time and have had pretty good success finding all kinds of malware, either manually through checking registry locations and typical file system hiding places, but this one is kicking my butt. The infector appears to be no longer completely functional: it doesn't redirect any more and when it tries to run the Debugger pops up instead of doing what it's supposed to do; but parts of it are still working (cf. the outbound connections in netstat). I don't want to delay the user any more than I have to, but I really want to understand what kind of beastie has infected this machine.

Thanks in advance for your wisdom, expertise, and for your patience with an old dog who still has to learn some new tricks.
