Our network consisting of 600 clients and 70 servers went down totally because of this worm on the 5th of January, and we were promised a fix from Kaspersky within a day or two....still nothing
However, we have managed to manually (and with a little help from our SCCM server) clean the entire network! As long as you have a virusdefinition from around the 10th of January you can beat this thing. Here's a quick guide to how we did it:
1. ALL computers in your network must have the update KB958644! Download from a healthy pc and deploy either via SMS, SCCM or the Kaspersky admin kit, loginscript or manually. Remember to NEVER login to an infected PC with a domain account, use the local administrator!
2. Stop the SERVER service on all computers, except for your AD servers, I'm not sure the effect it might have on AD servers.
3. Believe it or not, Microsoft's malicious software removal tool removes the virus and the file that is locked after a reboot! First you need to disable autoplay, since if the virus has spread to some network shares (and it has), your computers will be infected again as soon as they try to connect to the shares. This can be done with a GPO, however, this doesn't work since the autorun.inf is still read, and that triggers the infection of your pc. Better way is to make Windows ignore autorun.inf files completely, and this is done with the following regfile: Save as regfile and import. This one works on both workstation and servers.
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\Autorun.inf]
@="@SYS:DoesNotExist"
4. After setting the value in the registry, run the Malicious software removal tool (called Windows kb - 890830-v2.6.exe) with the /q switch. Check the log in C:\Winnt\Debug\Mrt.log to see that the virus service and file has been deleted, or will be deleted after a reboot.
5. Go to the following key in the registry: HKLM\Software\Microsoft\Windows NT\Current Version\SvcHost. Doubleclick "netsvc" and check the value at the bottom to see if it matches the name you could see in the Mrt.log file in step 4. Remove the value.
6. Go to SERVICES, and enable BITS and Automatic updates again.
7. Reboot your Pc and enjoy a worm free machine.
A little tip though: Start with your servers, and if necessary, reboot them in safe mode to remove the infected files which Kaspersky should find on the shares.
Thanks for nothing to kaspersky for not fixing this for us....
