IMO, Kapersky seems to be the least problematic.
IS does work with most AV products, although the ol Windows Defender/Security Essentials (depending on your Windows version) is the one which gets the least upset about it. Others you can sometimes work around their annoying interference by setting exclusions (not looking at Nortons at all.....). Trend just doesn't seem to want to play nice currently.
Yep, Windows Defender is low on the list of high class products, BUT, it depends on what crappy websites you hang out at. If you are downloading a bunch of torrents, watching the pr0nz, searching for lots of cheatz, hackz, and warez, and open every email from Nigerian Princes promising riches if you only just send a release fee of $300 first, you will probably need something better.
You will probably also want something better if you travel, hook up to lots of public Wifi, and don't manage the Windows firewall manually or use a secure VPN that routes through a decent firewall with built in AV detection.
