My girlfriend's computer will not install any programs or run any programs that are currently installed on it, someone else tried to wipe the hdd but everytime the computer is connected to the internet it gets random pop-ups and messages, the computer also will not start in safe mode, and has no system restore points. I was able to run hijackthis.

Thank you for the quick reply Fireman4it, i tried to do as you instructed, Rkill ran fine, however when I attempted to install the recovery console combofix alerted me that it was unsafe to continue I got an error stating that the file had been compromised and i may be infected with "virut"

Hello,


I'm afraid I have very bad news.

Your system is infected with a nasty variant of Virut, a polymorphic file infector with IRCBot functionality which infects .exe, .scr files, downloads more malicious files to your system, and opens a back door that compromises your computer. According to this Norman White Paper Assessment of W32/Virut, some variants can infect the HOSTS file and block access to security related web sites. Other variants of virut can even penetrate and infect .exe files within compressed files (.zip, .cab, rar). Virux is an even more complex file infector which can embed an iframe into the body of web-related files and infect script files (.php, .asp, .htm, .html, .xml). When Virut creates infected files, it also creates non-functional files that are corrupted beyond repair and in some instances can disable Windows File Protection. In many cases the infected files cannot be disinfected properly by your anti-virus. When disinfection is attempted, the files become corrupted and the system may become irreparable. The longer virut remains on a computer, the more critical system files will become infected and corrupt so the degree of infection can vary.

QUOTE
The virus disables Windows File Protection by injecting code into the "winlogon.exe" process that patches system code in memory.
CA Virus detail of W32/Virut

QUOTE
The virus has a number of bugs in its code, and as a result it may misinfect a proportion of executable files....some W32/Virut.h infections are corrupted beyond repair.
McAfee Risk Assessment and Overview of W32/Virut

QUOTE
There are bugs in the viral code. When the virus produces infected files, it also creates non-functional files that also contain the virus...Due to the damaged caused to files by virut it's possible to find repaired but corrupted files. They became corrupted by the incorrect writing of the viral code during the process of infection. undetected, corrupted files (possibly still containing part of the viral code) can also be found. this is caused by incorrectly written and non-function viral code present in these files.
AVG Overview of W32/VirutThis kind of infection is contracted and spread by visiting remote, crack and keygen sites. These type of sites are infested with a smörgåsbord of malware and an increasing source of system infection. However, the CA Security Advisor Research Blog says they have found MySpace user pages carrying the malicious Virut URL. Either way you can end up with a computer system so badly damaged that recovery is not possible and it cannot be repaired. When that happens there is nothing you can do besides reformatting and reinstalling the OS.

QUOTE
...warez and crack web pages are being used by cybercriminals as download sites for malware related to VIRUT and VIRUX. Searches for serial numbers, cracks, and even antivirus products like Trend Micro yield malcodes that come in the form of executables or self-extracting files...quick links in these sites also lead to malicious files. Ads and banners are also infection vectors...
Keygen and Crack Sites Distribute VIRUX and FakeAV

If your computer was used for online banking, has credit card information or other sensitive data on it, you should 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 using a clean computer and not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:Virut is not effectively disinfectable. Your best option is to perform a full reformat as there is no guarantee this infection can be completely removed. In most instances it may have caused so much damage to your system files that it cannot be completely cleaned or repaired. In many cases the infected files cannot be deleted and anti-malware scanners cannot disinfect them properly. 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. 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. Please read:
