Some information about Sality for you:
Win32/Sality is a dangerous polymorphic file infector which infects .exe, .scr files, creates a peer-to-peer (P2P) botnet that compromises your computer, downloads more malicious files to your computer, steals sensitive system information/passwords and sends it back to the attacker.
-- Note: As with most malware infections, the threat name may be different depending on the anti-virus or anti-malware program which detected it. Each security vendor uses their own naming conventions to identify various types of malware.
With this particular infection, the safest solution and only sure way to remove it effectively the majority of the time is to reformat and reinstall the OS. These quote below explain why:
As an entry-point obscuring (EPO) polymorphic file infector, the virus gains control of the host body by overwriting the file with complex and encrypted code instructions. The goal of the complex code is to make analysis more difficult for researchers to see the real purpose and functionality implemented in the code...Infected files will have their original, initial instructions overwritten by complex code instructions with the encrypted viral code body located in the last section of the file.
Symantec's Assessment of Win/32Sality
As with many other malware, Sality disables antivirus software and prevents access to certain antivirus and security websites. Sality can also prevent booting into Safe Mode and may delete security-related files found on infected systems. To spread via the autorun component, Sality generally drops a .cmd, .pif, and .exe to the root of discoverable drives, along with an autorun.inf file which contains instructions to load the dropped file(s) when the drive is accessed.
About Sality Virus

The infection is often contracted by visiting remote, crack and keygen sites. These type of sites are infested with a smörgåsbord of malwareand a major source of system infection.
That being said, I can try to help you clean Sailty off your computer. It must be known there is a chance your computer could easily become reinfected during the process, or end up becoming unbootable as cleaning viruses is not an easy process. It is probably quicker and safer to save any files you want to keep and then reinstall. Let me know what you want to do.
