AV-Comparatives summary report 2013
Product of the year goes to Kaspersky Internet Security.
Top Rated products for 2013 are Bitdefender, ESET, F-Secure, Avast, BullGuard, Fortinet and AVIRA.
File Detection Winner(high detection rate of malware without causing too many false alarms): F-Secure (99.6%)
Additional F-Secure notes
Sophos, Avast, F-Secure, Kaspersky Lab and Bitdefender demonstrated a lower impact on system performance than other products.
When the real-time protection of F-Secure discovers malware on a flash drive, the alert shown is clear, reassuring, and does not require any user interaction; experts users can however see further details.
If protection components are disabled, F-Secure and Trend Micro supplement the rather fleeting warning from Windows Action Center with their own, much more obvious and persistent warnings.
