You have a nasty infection on your system. Virut/Virtob
is a file infector virus with IRC bot functionality which infects all .exe and .scr files
, downloads more malicious files to your system, and opens a back door that compromises your computer
. In many cases the infected files cannot be deleted and anti-malware scanners cannot disinfect them properly. When disinfection is attempted, the files become corrupted and the system may become irreparable
. Please read miekiemoes' Blog on Virut
Virut/Virtob is contracted and spread by visiting remote, crack and keygen sites
. Those who attempt to get software for free may end up with a computer system so badly damaged that recovery is not possible and a Repair Install will NOT help!
Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards. Starting over, reformatting the drive and performing a clean install removes everything.
If your computer was used for online banking, has credit card information or other sensitive data on it, you should immediately disconnect from the Internet until your system is cleaned. All passwords should be changed immediately
to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised
. You should change each password by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach.
There is no guarantee the infection can be completely removed. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:
"When should I re-format? How should I reinstall?
"Help: I Got Hacked. Now What Do I Do?

Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. If you wish to proceed, disinfection will require the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a hijackthis log.
Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log
". If you cannot complete a step, then skip it and continue with the next. In Step 9
there are instructions for downloading the HijackThis Installer and creating a log. This is an automatic setup version which will install the program in the proper location.
When you have done that, post your log
in the HijackThis Logs and Malware Removal
forum, NOT here
