Re: [incidents] RE: AIM Password theft

[Tim Kennedy <tim () timkennedy net>]

CA's eTrust EZ Deskshield/Mail Watcher tell you when emails or web pages are 
a) trying to access your filesystem
b) trying to access your email systems

So far, even though MS Update says I'm completely up to date, Mail
Watcher has notified me when I hit the sample url:
http://www.heise.de/security/dienste/browsercheck/demos/ie/htacheck.shtml

that the web page was trying to access the filesystem, and gave me a
chance to disallow permissions.

The eTrust AV client also recognizes the code as the 
VBS.ObjectDataHTA virus, and tried to clean it up, although it says:
File status: Cure failed, file restored.

But it at least stopped it from modifying files on my system.
