Microsoft's February security bulletin.

QUOTE
Windows users are being urged to install Microsoft's February security update which contains 12 patches for 20 vulnerabilities.

The bumper package includes fixes for loopholes that malicious hackers are known to be already exploiting.

Another vulnerability is in the program Microsoft designed to spot viruses and spyware that has infected PCs.

Half of the patches in the update have been rated as critical; criminals exploiting these could take over a PC.


It's safe to assume pretty much everybody may be using automatic updates for their Windows OS, however, let this thread serve as a reminder just to play it safe.

These updates do not affect Windows Vista.
