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 Trojan-PSW's file once a user opens a drive's folder in Windows Explorer.

Process activity

The Trojan-PSW creates the following process(es):

adsey.exe:1316
adsey.exe:368
tasklist.exe:1488
%original file name%.exe:1120

The Trojan-PSW injects its code into the following process(es):

credwiz.exe:1788
service.exe:252
service.exe:1156
PrintBrmPs.exe:184

File activity

The process %original file name%.exe:1724 makes changes in the file system.
