I have 150 ish machines on eset across a few different clients, obviously my experience with it has been very good over the years in all aspects. Eset don't offer the biggest margins but I stick with them because it doesn't cause support issues and I can count the number of infected eset machines I've had to deal with on one hand.

McAfee in particular aggressively pushes "free trials" (often getting them bundled into the installers of unrelated software) that will then show scarily-worded warnings encouraging you to buy once the trial has expired.

I recommend going by test results and by the features that interest you most.

Kaspersky, BTW, has the best scores (See here: https://bestantivirus.reviews/tools/test-results-calculator) but Bitdefender and Avira are also great according to these tests, and Bitdefender is my choice, personally.

Kaspersky just worries me because of the Russian connections https://www.bloomberg.com/news/articles/2015-03-19/cybersecu...

It's sort of like Cloudflare protecting against DDoS attacks while also protecting booters.
