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.

Removals

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:1076
   

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

   %Documents and Settings%\%current user%\Local Settings\Temp\nsr3.tmp\System.dll (11 bytes)
   %WinDir%\system.ini (70 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temporary Internet Files\Content.IE5\desktop.ini (67 bytes)
   %Documents and Settings%\%current user%\Local Settings\History\History.IE5\desktop.ini (159 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\nsr3.tmp\SPTool.dll (101109 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\nsg2.tmp (80185 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temporary Internet Files\Content.IE5\OPQNSD2J\CARRIER_ID[1] (892 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\nsx4.tmp (892 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temporary Internet Files\Content.IE5\OPQNSD2J\desktop.ini (67 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\0007F1A1_Rar\%original file name%.exe (69845 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\nsr3.tmp\inetc.dll (784 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\wgxb.exe (561 bytes)

4. Clean the Temporary Internet Files folder, which may contain infected files (How to clean Temporary Internet Files folder).
   
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.
