I used to use free AVG... but they got all spammy with their pops that I'm just "done" with them.
I use McAfee... but only because I get it for free as "homeware" thru my day job.
Sadly; I don't have any real recommendations except to avoid AVG because of the spammyness of their software.
I'd also stay away from Kaspersky because they are state-run-Russians. I'm sure China has a company or two.
