I've got a Windows 7 64-bit system with some odd behavior, perhaps from some virus or attack:

  -Internet Explorer 32-bit does not start (launch with rapid exit)
  -Firefox 32-bit does not start (launch with rapid exit)
  -Chrome 32-bit does not start (launch with rapid exit)
  -Updating Malwarebytes fails
  -Updating SuperAntiSpyware fails
  -Ran ComboFix multiple times, but no log file was created

But the following work:

  -Internet Explorer 64-bit works fine
  -Spybot Search and Destroy updates fine
  -Norton 360 is corrupted and won't uninstall (immediate exit)

I've tried the following:

  -Re-started with non-Microsoft services disabled
  -Scanned with Spybot, SuperAntiSpyware and MalwareBytes
  -Ran SFC /scannow (no errors)
  -Reset Internet Options, security, etc.
  -Ran CHKDSK /f on c: drive

I'm kind of out of ideas at this point. Any help appreciated!

Sounds maybe like a rootkit virus? or corrupted install... There is no reason that your 32bit and Malware/AV checkers should not run otherwise.
Try the malwarebytes rootkit remover - http://www.malwarebytes.org/products/mbar/

If malwarebytes is not dating then try it Hitman pro you can do it 30 day free trial on it then then you can update malwarebytes  and do a quick scan then you should be good its happen to me too

Boot the computer in safe mode with networking and check whether u can browse website in 32 bit

Also check proxy settings in IE.

If everything works in safe mode with networking then problem is caused by non microsoft software ..might be running at startup.

Before running MalwareBytes or Combofix, etc., try running RogueKiller or Rkill to stop malware processes that can interfere with scanners.  Then run TDSSKiller, MalwareBytes, etc.  Have a look at this article.

can you take the drive out of the computer and slave it to another computer? Run your antivirus and anti malware  programs from the second computer.
