Some infections will also hide all the files on your computer. To make your files visible again, please download the following program to your desktop:
Once the program has been downloaded, double-click on the Unhide.exe icon on your desktop and allow the program to run. This program will remove the +H, or hidden, attribute from all the files on your hard drives. If there are any files that were purposely hidden by you, you will need to hide them again after this tool is run.
You also might want to post a Hijackthis log on one of the specialist forums that deal with them to see if you are clear of infection.
Do not post Hijackthis logs here, we can't help you with those !
Post the logs at one of these specialist Forums:
Be sure to read all the sticky announcements/instructions at the top of each malware forum!
