Using F-secure at home, but considering changing my mom's AV from eTrust (free from her ISP) to AOL Active Virus Shield. Certainly a stripped-down KAV clone is appealing, but eTrust has dedicated email scanning. I'd say knowing my mom's surfing habits that email vulnerability is the biggest concern. But I also realize that AOL Active Virus Shield will scan email-borne malware before it loads. I'd also add that I like the unobtrusiveness and lightness of eTrust on my mom's machine. Opinions?
