Hi,

First we need to verify that you do indeed have virut.

If this is the case. There is nothing to do but reformat and re-install your operating system as virut is a polymorphic file infector and will have destroyed pretty much every file on your system.

Please do the following:

  • Make sure to use Internet Explorer for this
  • Please go to VirSCAN.org FREE on-line scan service
  • Copy and paste the following file path into the "Suspicious files to scan" box on the top of the page:

    c:\windows\explorer.exe
  • Click on the Upload button
  • If a pop-up appears saying the file has been scanned already, please select the ReScan button.
  • Once the Scan is completed, click on the "Copy to Clipboard" button. This will copy the link of the report into the Clipboard.
  • Paste the contents of the Clipboard in your next reply.


Please do the same for the following files:

c:\windows\system32\userinit.exe
c:\windows\system32\ctfmon.exe
c:\windows\system32\svchost.exe

It shouldn't. - what program told you that you had virut.

If you have any logs from all of the scans you have performed (especially Dr.Web - please post them)

Hi,

Virut cannot be cleaned - regardless of what the scanner says about removing the infection. There are always traces left that will eventually respawn.

You will need to do a total reformat/reinstall...

I will post my usual explanation for virut:



VIRUT
is a polymorphic file infector with some additional features. It spreads all around the drive and infects even files infected by another virus previously.

Unfortunately, the cleaning of this virus is not recommended.

The only thing we recommend is to do a full reformat and install.

We have an excellent tutorial on how to reformat here

Things to bear in mind, only back up data files (word, excell etc.) DO NOT backup any .exe/.scr/.htm/.html/.xml/.zip/.pif/.com/.rar files... as they could all be infected and will simply re-infect your system again, there is no way of being certain what this infection can do.

Read more about the VIRUT FILE INFECTOR HERE

If you don't have a Windows Installation Disk (if this came with Windows pre-installed), you may have a Manufacturer restore disk to restore the computer to its original state - this depends on the Manufacturer though. Otherwise, give the Manufacturer a call and ask them to send you a restore disk or Windows installation CD.

Here is a guide on backing up your data;
Although you can use whatever method you prefer.

Do not back up to another machine, as it may become compromised.

Burn to DVD/CD, or to an external drive which has nothing else on it, and which you can format should it happen to become infected from the backups.

Should you have any questions, please feel free to ask.

I am sorry there is nothing more that we can do.

There are bugs in the viral code. When the virus produces infected files, it also creates non-functional files that also contain the virus.

http://home.mcafee.com/VirusInfo/VirusProf...aspx?key=143034
W32/Virut.h is a polymorphic, entry point obscuring (EPO) file infector with IRC bot functionality. It can accept commands to download other malware on the compromised machine.
It appends to the end of the last section of executable (PE) files an encrypted copy of its code. The decryptor is polymorphic and can be located either:
Immediately before the encrypted code at the end of the last section
At the end of the code section of the infected host in 'slack-space' (assuming there is any)
At the original entry point of the host (overwriting the original host code)



Miekiemoes
, a highly regarded expert in malware removal, and an MS-MVP,
has an extremely informative blog post about Virut. - she only ever recommends a total reformat.

At least this way, you have the best chance of having a clean machine once more.

For future protection read this very well written article Think Prevention.
