The Worm modifies "%System%\drivers\etc\hosts" file which is used to translate DNS entries to IP addresses.
The modified file is 544 bytes in size. The following strings are added to the hosts file listed below:

Rootkit activity

No anomalies have been detected.

Propagation

A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Worm's file once a user opens a drive's folder in Windows Explorer.

Remove it with Ad-Aware

1. Click (here) to download and install Ad-Aware Free Antivirus.
2. Update the definition files.
3. Run a full scan of your computer.

Manual removal*

1. Terminate malicious process(es) (How to End a Process With the Task Manager):
   

   %original file name%.exe:1180
   

2. Delete the original Worm file.
   
3. Delete or disinfect the following files created/modified by the Worm:
   

   %WinDir%\userinit.exe (113 bytes)
   %WinDir%\kdcoms.dll (44 bytes)
   %System%\system.exe (113 bytes)

4. Restore the original content of the HOSTS file (%System%\drivers\etc\hosts):
   127.0.0.1 localhost
   
5. Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
   
6. Reboot the computer.
   

*Manual removal may cause unexpected system behaviour and should be performed at your own risk.
