Hello if ComboFix showed Virut and could not remove then please read.....
Your system is infected with a nasty variant of Virut
, a polymorphic file infector
functionality which infects .exe, .scr files
, downloads more malicious files to your system, and opens a back door
that compromises your computer
is an even more complex file infector which also infects script files (.php, .asp, and .html). When Virut creates infected files, it also creates non-functional files that are corrupted beyond repair. 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
McAfee Risk Assessment and Overview of W32/Virut
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.
This kind of infection is contracted and spread by visiting remote
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.
Keygen and Crack Sites Distribute VIRUX and FakeAV
...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...
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 this infection can be completely removed
. In some instances it 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:
If you insist on trying to fix this infection instead of following our advice to reformat and reinstall your operating system, there are various rescue disks available from major anti-virus vendors which you can try. Keep in mind, even the vendors like Kaspersky say there is no quarantee
that some files will not get corrupted during the disinfection process. In the end most folks end up reformatting out of frustration after spending hours attempting to repair and remove infected files. IMO the safest and easiest thing to do is just reformat and reinstall Windows. Bleeping Computer DOES NOT assume any responsibility for your attempt to repair this infection using any of the following tools. You do this at your own risk and against our advice.
