Network activity (URLs)

No activity has been detected.

HOSTS file anomalies

The Virus modifies "%System%\drivers\etc\hosts" file which is used to translate DNS entries to IP addresses.
The modified file is 858 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 Virus'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):
   

   WINMINE.EXE:2260
   WINMINE.EXE:556
   NOTEPAD.EXE:3084
   NOTEPAD.EXE:3216
   NOTEPAD.EXE:3156
   NOTEPAD.EXE:2520
   netsh.exe:3064

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

   %Documents and Settings%\%current user%\Local Settings\Temp\whsl.exe (601 bytes)
   %WinDir%\system.ini (70 bytes)
   %Program Files%\Common Files\Adobe\ARM\1.0\AdobeARM.exe (31 bytes)
   %Program Files%\Adobe\Reader 9.0\Reader\Reader_sl.exe (528 bytes)
   %System%\dllcache\zipexr.dll (1137 bytes)
   %Program Files%\Common Files\Java\Java Update\jusched.exe (368 bytes)
   %System%\drivers\etc\hosts.tmp (1592 bytes)

4. Delete the following value(s) in the autorun key (How to Work with System Registry):
   

   [HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
   "soundmix" = "%System%\soundmix.exe"

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

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