A very BIG Virus Problem.

Working with a company that has 15 terminals.  Almost all of them have gotten a program installed that shows no name, but immediately after a few office updates are removed from the system.  To date, ESET NOD32 Version 4 has not been able to detect this - even with a bootable CD.  AVG has not found it either.  Malware Bytes Anti-Malware does not find it and it gets Error 732 when trying to update.

This is a big problem, as it sure seems like a virus, but I have yet to be able to identify or kill it with confidence.  It seems to make browsing the net this side of impossible - with 2 or 3 searces, the user must reboot.  And slows computer.

Try running tdsskiller to see if it finds and removes the infection:

Download the file TDSSKiller.zip and extract it into a folder
Execute the file TDSSKiller.exe.
Wait for the scan and disinfection process to be over.

If unsuccessful, try Hitman Pro 3, a Second Opinion Malware Scanner.  It's often quite successsful:

If still unresolved i suggest running Combofix.
Download ComboFix and save to your Desktop, from here>
http://download.bleepingcomputer.com/sUBs/ComboFix.exe

Before using ComboFix please disable any realtime Anti-virus, Anti-spyware, Shields, etc. that you may have running.
Also it may be necessary to rename ComboFix.exe (to Combo-Fix.exe for example), before saving it to your desktop.  If you have difficulties downloading it, try downloading to another machine, then into a USB memory stick or CD.  Rename it and carry to the infected machine.

Double click "combofix.exe" and follow the prompts.
When it's finished it will have produced a Logfile, probably at C:\ComboFix.txt.
You could post that log here please.
In case of unfamiliarity, please do not mouseclick Combofix's window while it is running because it may stall.  It is absolutely normal for you to see a blue screen with flashing cursor, and this can last for up to 25 mins.
ComboFix must be run in normal mode.

If (or when) you run Malwarebytes again, try the following if you're still getting error 732 >>

Control panel > internet options > connections tab > "LAN settings" button,
then uncheck the box "use a proxy server", and instead check box "automatically detect settings."  
Apply, and ok your way out.....now try updating Malwarebytes.

Try running SuperAntiSpyware portable.
You can download it at http://superantispyware.com/portablescanner.html

I would also suggest using rkill to terminate any malware processes that are running.
you can download it at http://www.bleepingcomputer.com/forums/topic308364.html

Another thing not mentioned that I have had good luck using is GMER rootkit detector. you can get it at http://www.gmer.net/

@ go2dave  .... RKill is certainly an excellent package, although the GMER rootkit detector you'll find is contained within ComboFix and is usually listed near the end of the final ComboFix logfile, like this>

I have had a few virus infections at a reasonably large site (~300 computers) which have infected quite a few machines.  Both Malwarebytes and SuperAntiSpyware have failed to identify infections along with Norman, which lists mosts modern 'minor' infections as a generic.

I've had to resort to dealing with pretty much all the infections manually.  I use HijackThis to find out what's running on startup, and Process Killer by Beyond Logic to kill processes with a command prompt.  It will also kill system processes which Task Manager prevents you killing.

I've also had to search through the registry for file names which are related to these infections and remove the entries.  We had one (I think it was a variant of Conficker) which kept coming back until I finally uncovered that it required the KB958644 security update.  This update didn't seem to be available on Windows Update but I was able to download it manually and it prevented the computers reinfecting each other.

As we're on a Novell network, for a couple of issues I have written batch files to manually kill processes and remove files when I know how to fix the problems.  I can then launch these batch files from startup.bat.

I have dropped to safe mode and could delete the Windows\Temp areas, User Temp areas, internet explorer cache and that appears to have gotten rid of it.

I say appears, because I could never identify it and all the utilites listed did not seem to find anything.  Kinda scary, but once I cleared the temp areas - IN SAFE MODE - the machines all run normally again.

I will try to split the points.
