Hi, this is a question that
will be answered. A lot of us here have a distaste for Norton and McAfee products, for various reasons.
IMHO, Paid products #1 kapersky, #2 bitdefender, #3 Nod32, #4 Panda, #5 Trend Micro.
Free Products: #1 Avast, #2 Avira, #3 AVG (these all have active protection)
Freeware Replacement threadIMO you must run an antivirus that has active protection. There are other Free antiviruses available, such as bit defender Free, but the last I looked at it, it just put an icon in the system tray, but still only had manual (on demand) scanning.
