How to fix the "Windows Security Update" Worm.

I for the second time got caught out by a virus - I recived an e-mail with attachment supposedly from Micro$oft regarding an update patch for Outlook.

I saved the file intending to scan it but I could'nt as saving let the little fvcker loose.

The worm is called Swen and the file is called SIWPNZRT.EXE This file will do a number of nasty things causing for example all exe files not to open stopping access to files accessed from the RUN box, disabling anti-virus software and much more besides.

So first run find for SIWPNZRT and then do the following -
copy and paste-

Start
;Registry fix for Swen worm
[Version]
Signature="$CHICAGO$"

[DefaultInstall]
AddReg=FixSwen

[FixSwen]
HKCR, "exefile\shell\open\command",,0,"""%1"" %*"
HKCR, "comfile\shell\open\command",,0,"""%1"" %*"
;End

into notepad and save on desktop as .INF file

locate file and right click select INSTALL.

Then get this http://srnmicro.com/downloads/SwenFix.exe
and run.

Then once clear reinstall your anti-virus software....

Hope this helps someone else who was'nt paying attention!
