Behaviour	Description
WormAutorun	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.

Process activity

The Worm creates the following process(es):

%original file name%.exe:1064
winini.exe:3416

The Worm injects its code into the following process(es):

cvtres.exe:3884

Mutexes

The following mutexes were created/opened:No objects were found.

File activity

The process %original file name%.exe:1064 makes changes in the file system.

The Worm creates and/or writes to the following file(s):

%Documents and Settings%\%current user%\Local Settings\Temp\winini.exe (274 bytes)

The process winini.exe:3416 makes changes in the file system.

The Worm creates and/or writes to the following file(s):

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

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

Manual removal*

Terminate malicious process(es) (How to End a Process With the Task Manager):
%original file name%.exe:1064
winini.exe:3416
Delete the original Worm file.
Delete or disinfect the following files created/modified by the Worm:
%Documents and Settings%\%current user%\Local Settings\Temp\winini.exe (274 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\cvtres.exe (35 bytes)
%Documents and Settings%\%current user%\Application Data\JR84IXUYRY.exe (35 bytes)
%Documents and Settings%\%current user%\Application Data\keylogg34342 (34 bytes)
Delete the following value(s) in the autorun key (How to Work with System Registry):
[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"Windows Live" = "%Documents and Settings%\%current user%\Local Settings\Temp\winini.exe"
Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
Reboot the computer.

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