Close32

Viruses and worms
1

A few minutes after I boot up my computer and start working on programs, a little “Close32” window shows up and closes down all my programs and shuts down the computer. I try to catch it in the Task Manager or using a freeware program called “What’s Running?” but I cannot see what’s causing it to run or how to stop it.

From what I can tell, it isn’t damaging any files – it’s just shutting down programs and the computer. Is this a virus/worm . . . or something else?

I suggest:

  1. Disable System Restore and then reenable it again.
  2. Clean your temporary files.
  3. Schedule a boot time scanning with avast with archive scanning turned on. If avast does not detect it, you can try DrWeb CureIT! instead.
  4. Use SUPERantispyware, MBAM or Spyware Terminator to scan for spywares and trojans. If any infection is detected, better and safer is send the file to Quarantine than to simple delete than.
  5. Test your machine with anti-rootkit applications. I suggest avast! antirootkit or Trend Micro RootkitBuster.
  6. Make a HijackThis log to post here or, better, submit the RunScanner log to to on-line analysis.
  7. Immunize your system with SpywareBlaster or Windows Advanced Care.
  8. Check if you have insecure applications with Secunia Software Inspector.

If you can’t boot or install new program, try, at least, full computer on-line scanning:
Kaspersky (very good detection rates)
ESET NOD32
Trendmicro housecall
F-Secure
BitDefender (free removal of the malware)
