Win32:PowerSpider-F [Trj]

Viruses and worms

Does anyone know anything about this virus?

It keeps coming back again and again, I load into Windows, log off, run the Bart CD it picks it up, I remove it, rinse and repeat each day it comes back. ???

This is what the Bart CD is picking up;

Seems false positive as both files are temporary, one the hibernation file and other the virtual memory. Hope Alwil team correct these false positives soon.

3

not a false positive, since pygefile.sys contains a lot of garbage sometimes…

4

If it is not a false positive, I suggest:

  1. Disable System Restore and reenable it after step 3.
  2. Clean your temporary files.
  3. Schedule a boot time scanning with avast with archive scanning turned on.
  4. Use SUPERantispyware and/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.

wow see this problem has been affecting people since late december but just hot me.

Doing the boot scan now Tech.

Could it be that when I got my susspected MBR virus, it’s still there? And loading before anything else can and shielding itself hence why the Bart CD can only see it? As the MBR dosent start to load if I override it with CD/DVD boot?

Note sure if this is a good sign… or a bad one, nothing found :-\

avast 4.8 should be able to fix known variants of MBR rootkit (even without BART)… anyway, i can’t see any relation to hiberfil.sys and pagefile.sys… btw: these two files aren’t the right candidates to be scanned :slight_smile:

9

Ok, so I load up Bart again, do a scan, C:\pagefile.sys once again is infected, but this time two new virus;

C:\pagefile.sys INFECTED: Win32:QQHelper-X [trj]
C:\pagefile.sys INFECTED: Win32:Adloader-AC [trj]

They was found each at different times, and with a new Bart CD. :-\
