Carnage, we can start a new thread on this if needed (because: ermagherd, zombie threadz!), but I'm curious how you choose which AV is good. I know for myself, I judge first and foremost on resource usage. I've not seen a lighter footprint than Webroot, and I've tried a ton of them.
The second is, obviously, detection rate. Webroot is truly cloud based, so as long as it's connected (which is when it's vulnerable) it's as up to date as the company's definitions, which are usually hourly updates.
Third is issues. Kaspersky causes keyboard to quit working (keyboard filters), Norton will lock down a network when the sub expires, etc. They ALL cause their conflicts, but with Webroot I've seen far fewer issues. Especially with the newer Secure Anywhere version since it's just a light little shell. I've only seen one startup problem related to a Microsoft KB and Webroot. Was solved same day by Webroot.
When we're talking about these freebies (besides MBAM - they're really damn good for free), what's your personal experience in each area that I've mentioned? My biggest hangup on the freeware is bloat and slug followed immediately by lack of detection. Many aren't as problematic as Norton and McAfee, but if they slow me down and/or can't catch the common crap, then there's no point to installing them, either.
