If you've been worrying about computer security for awhile, you might remember when macro viruses in Microsoft Word and Excel files were at the top of the exploit list. These file formats, along with the omnipresent Adobe Reader PDF format, are once again among the biggest threat vectors being exploited by today's malware, according to a new report from the Microsoft Malware Protection Center. Fittingly, the full report and a condensed key findings version are available in either PDF or Microsoft's own XPS formats. These reports cover the July-December 2008 period.

Some key findings include:

• Scareware (which Microsoft calls "rogue security software") is on the rise, including the latest versions of our old friend  Antivirus XP.
• A slight reduction in unique vulnerability disclosures from 2007, but the High (most serious) category was larger in the second half of 2008 than in the first half of the year or the second half of 2007.
• Applications continue to be the biggest target (86.7%, with browsers at 8.8%, and operating systems at only 4.5%)
