I have that my laptop has a virus identified by Symantec as W32.Virut.U but it is just being cleaned. Further investigations show that the files that are being left alone are;
sembako-chzjlih
bbm-yqplihhc
cmd-bro-ilx
DXBLBM
br79llon
All these files are located in this folder;
D:\Documents and settings\user account\local settings\application data\
or
D:\Documents and settings\user account\application data\
Attempts to navigate to the said locations to remove the files manually have resulted in the device shutting down automatically. The regedit command will not work and so does the mscofig command as the device will shut down. Symantec will not delete the virus or even pick it up.
The virus is creating .exe files that bear the name of the home folder (in a folder named Videos there will be another folder named Videos.exe that is approx 148kb in size).

Please assist. :thumbsup:

Your system is infected with a nasty variant of Virut (Virtob) / Virux, polymorphic file infectors with IRCBot functionality which infects .exe, .scr and script files (.PHP, .ASP, and .HTML), downloads more malicious files to your system, and opens a back door that compromises your computer. Virut has a number of bugs in its code, and as a result, when the virus creates infected files, it also creates non-functional files that are infected (corrupted) beyond repair. Virux is a more complex infector. 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.Virut/Virux are contracted and spread by visiting remote, crack and keygen sites. These kind of sites are infested with a smörgåsbord of malware and an increasing source of system infection. Those who attempt to get software for free 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.

...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: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. 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:

Thank you for the response. I have seen that if I backup my profile on an external HDD I will be able to view the said .exe files and remove them. After removal I have successfully restored the files without any complications and I hope that remains that!!!!

Is there no removal tool that can rid me of this virus in future???

Do you plan on going back to those same infected sites?

AVG Win32/Virut Remover. It was last updated in August 2008 and is not always effective for the reasons I indicated earlier. Manual removal is usually required but it can be tedious and even then there is no quarantee.

I will not be visiting the sites again!!!!(Not that I did visit them) I think the virus came in via flash disk as the folder identified by Symantec carries the name My Project.exe.

Tips to protect yourself against malware and reduce the potential for re-infection:Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:If using Windows Vista, please refer to:
