Maybe you heard something about a new vulnerability that could expose Windows (all versions) to trojans, spyware, etc. just by viewing a web page? Since it’s a problem with nearly all versions of Windows not browsers, users of Firefox, Opera, and others need the patch just as much as IE users.
Go get the Microsoft patch now!
Update: The best solution is to activate the Windows Update service to ensure critical patches like this are downloaded automatically.
Mac and Linux users – Even though you’re not affected, you could always take this opportunity to get whatever security updates are available for your OS. Staying vigilant is never a bad idea…
