Microsoft patented Proactive Virus Protection

Microsoft left that patent on year 2004 but it got accepted on Tuesday. Similar technique has been used in virus protection for a long time.

This is based on comparison about similarities between a possible malware and information already in database.

For example McAfee and Norton have used similar technique for years before Microsoft's patent.

We'll see if Microsoft contacts McAfee, Norton, Kaspersky etc. soon for some fees.
