I am aware of the options and reviews, just interested in personal experiences. I am not interested in "security suites", just protection from malicious downloads. I have used Avast years ago and was satisfied, but don't have recent experience with them. I want an effective (frequently updated) active monitor with minimal Vista-type nag screens. Often even the products with best reviews have some "features" that in the end are deal-breakers (i.e MSE), and they often focus primarily on detection effectivess (to a non-defined threat load) and scan speed only.
