Security experts at PC Tools have predicted November 24, three days before Thanksgiving, as the peak of virus activity for the year 2008.
In 2007 as well, virus, malware and other malicious activity peaked on this date, as millions of users purchased gifts from online stores making it the best time to steal financial information.
So be safe, and make sure your anti-virus, anti-spyware and firewall systems are up to date. (Thanks Guardian)
