In an earlier diary, we included a link to Microsoft's security web site that did not work.  Based on input from our readers we updated the link to one that seemed to work.  Microsoft told us today that there are two more URLs they would prefer that you use:

For home users:  http://support.microsoft.com/securityhome

For IT professionals:  http://support.microsoft.com/gp/securityitpro

In both cases, on right hand side there is a phone icon.  Under it is the "select your region" link (if the region is wrong).  For each region it links to the proper phone numbers for that region.
