Dr. Web has changed its layout and its procedures so some of your instructions might confuse a novice. I simply chose "Complete Scan" and it autoselected the fixed disks. Also, Dr.Web caused the "System Settings Protector" to crash. never seen that before. And it didn't like ComboFix and removed it from my desktop.

Thanks for the information, I'll correct that in the future.

As you've had Virut on your computer there is no way that I can say that it's gone. That is a really nasty file infector. I strongly recommend you to back up your important data (NO executables) like photos and documents. Then do a format and reinstallation. How to

Apart from that I can't see any signs of other malware.
If you feel that you are safe enough then follow this procedure to do the housekeeping


Step 1.
Clean up:

We need to do is to remove all the tools that you have used. This is so that should you ever be re-infected, you will download updated versions. It will also remove the quarantined Malware from your computer.

First:
Download ComboFix from one of these locations:

Link 1
Link 2
Link 3

* IMPORTANT !!! Save ComboFix.exe to your Desktop


  • Click START then RUN
  • Now type Combofix /u in the runbox and click OK. Note the space between the X and the /u, it needs to be there.

Second:

Double-click OTListIt2.exe to start it.
Click the Clean up button
Click Yes to the reboot.

Now delete any tools/logs that is left over after you ran OTListIt2 Clean Up.


Step 2.
Prevention:

OK, lets carry out a few preventative steps to make sure you reduce the risk of further infections.

First:
Your Adobe Acrobat Reader is out of date. Older versions are vunerable to attack.

Please go to the link below to download an update.

http://www.adobe.com.../readstep2.html

Remove the older versions and install the latest,


Second:
One of the essentials is to keep your computer updated with the latest operating system patches and security fixes. Windows Updates are constantly being revised to combat the newest hacks and threats, Microsoft releases security updates that help your computer from becoming vunerable. It is best if you have these set to download automatically.

Automatic Updates for Windows
  • Click Start.
  • Select Settings and then Control Panel.
  • Select Automatic Updates.
  • Click Automatic (recommended)
  • Choose a day and a time when you know the computer will be on and connected to the internet.
  • Click Apply then OK.


Third:
Now lets download some preventative programs that will help to keep the nasties away! We will start with Anti Spyware programs. I would advise getting a couple of them at least, and running each at least once a month.

Anti Spyware
  • SpywareBlaster to help prevent spyware from installing in the first place. A tutorial can be found here.
  • SpywareGuard to catch and block spyware before it can execute. A tutorial can be found here.
  • IESpy-Ad to block access to malicious websites so you cannot be redirected to them from an infected site or email. A tutorial can be found here
.
Note: If you find your system slows down after installing any of these, just uninstall it, or disable it from running at startup.


Fourth:
Next lets look at Firewalls. These help to prevent unauthorised access both to and from the internet or your local network. A firewall is considered a first line of defense in protecting private information. Below are two free firewalls to choose from, if you do not already have one. Note: You only need one firewall one your system.

Personal Firewalls
Fifth:
Nearly done! If you like to use chat, MSN and Yahoo have vunerabilities that can leave you open to infections. There are however a couple of very good, Malware free Instant Messenger programs which allow you to connect to multiple IM services in one program! (AOL, Yahoo, ICQ, IRC, MSN):

Instant Messengers
Lastly:
It is a good idea to clear out all your temp files every now and again with ATF Cleaner. This will help your computer from bogging down and slowing. It also can assist in getting rid of files that may contain malicious code that could re-infect your computer.


To find out more information about how you got infected in the first place and some great guidelines to follow to prevent future infections you can read this article by Tony Klein.


I will keep this log open for the next couple of days, so if you have any further problems post another reply here.

OK, all the best, and stay safe!

Thanks heir, your assistance is very much appreciated.

I suppose we could have taken the last step first since, as you say, one cannot be truly free of Virut without a "scorched earth" solution. Still I will study this thread to better understand the logs for future reference.

Once again, thanks very much for your efforts!
