With Firefox you can just leave out support for WMF files, or point it to your viewer of choice as with IE.

Symantec has a virus update for this one, if you use that service.

More handy news . . .
Firefox also has a plugin, called noscript, which allows you to selectively enable/disable Javascript, for those nasty Drudge style popups and nefarious scripts.

Is this link from Symantec:

related to the problem? It sounds so, but note the date of the announcement is early November, well before all of the news stories.
