This is bad. Tomorrow, everyone goes back to work and fires up there systems...security specialists around the web fear a major meltdown.
It's embedded in image (.wmf) files and takes advantage of an exploit in IE. So simply viewing any page containing malicious code will infect your system. Very nasty.

1) Run firefox. It's immune to this particular exploit.
2) Unregister the vulnerable .dll.
- Disable: Start > Run > regsvr32 /u shimgvw.dll
- After MS releases a patch you can restart it like so:
- Enable: Start > Run > regsvr32 shimgvw.dll
UPDATE: Some are saying that this doesn't protect you from the latest version of the exploit.

3) Reassign .wmf files to notepad.
4) Install third-party patch. (

5) Buy a mac.
Anyone else got any ideas?
