Let's get rid of Combofix now that we are (hopefully) finished with it.

• Click START then RUN
• Now type Combofix /u in the runbox and click OK. Note the space between the X and the U, it needs to be there.
  
  
  • 
  
  
• When shown the disclaimer, Select "2"

The above procedure will:

• Delete the following:
  • ComboFix and its associated files and folders.
  • VundoFix backups, if present
  • The C:\Deckard folder, if present
  • The C:_OtMoveIt folder, if present
• Reset the clock settings.
• Hide file extensions, if required.
• Hide System/Hidden files, if required.
• Reset System Restore.

==

See if that improves things.

Uh oh, pmkjh.dll regenerated itself and a number of new .dlls appeared..

Actually I think that the .dll seems to regenerate only when someone uses another account to sign on the computer. (after combofix)

After I used ATFCleaner everything on my browser is messed up, like I can't see images, etc.

Do a system restore and then download combofix again and run it on every user account on the pc.

Dude, I had the same problem. Here's what I did, I downloaded a version of avast4.8 home edition (free with registration) from www.avast.com. At the time I had McAfee VirusScan Enterprise 8.0i (thats another story though) and it obviously missed the virus too. Avast kind of took over the anti-virus services for my computer but it got rid of the virus and rootkits that I had. For you, download it from a different computer, also download the current virus library and put them on a external usb drive. I will tell you now, it will seriously mess up Norton and may conflict if you have them running simultaneously. But in your case it may not be a good idea to remove Norton just yet. If you want after the virus is gone, uninstall Avast and re-install Norton.

Install Avast! 4.8 and the virus library. It will ask you to put in the registration key but if you don't you still have 60 days of free service. It will also ask you if you wish to do a boot scan after installing, say yes. Avast has an anti-rootkit built into it and will protect itself from being overwritten, while remaining easy to uninstall. After installing you will be prompted to restart, and after doing so the boot scan shall start. This is the main reason why I love this product its the lowest price, everything in one (virus, malware, ad ware, rootkit) killer, and it has this great boot scan that does everything and more than the desktop version does. I use this program to kill all the nasties when I'm working (helpDesk Tech) or making a house call to a clients.
