Microsoft is warning users of Windows XP or Windows Server 2003 that a security hole in certain parts of Internet Explorer allows hackers to remotely install malicious viruses on unsuspecting users. The company is currently working to fix the breach.

The hole, apparently caused by the interaction of IE and ActiveX, has been used for about a week to install viruses on users who click certain links in spam emails. Microsoft's stopgap solution, available here, is to disable that video software, and the company is hard at work to fix the problem. Doesn't bode well for Microsoft's push into antivirus software, does it? [via AP]
