This coming up Tuesday, Microsoft is releasing some patches to fix vulnerabilities in Windows and Office. Make sure you get those machines patched, as there are several viruses in the wild taking advantage of these holes.

Proof-of-concept code has been published on the Internet that exploits that vulnerability, which affects older Windows systems running Internet Explorer. Microsoft suggested several workarounds until it releases a patch, including avoiding pressing the F1 key when prompted by a Web site.
