Top 10 Malware Threats for March
Sunbelt Software has announced the top 10 most prevalent malware threats for the month of March 2010. The list of detections for March shows the continued prevalence of Trojan horse programs circulating on the Internet and the growing trend of generic and behavior-based detections in antivirus detections.
