Using ESET for few years now. Working fine here (4.2,no betas). Have a slight annoyance which happened when 2 weeks before expire/renewal. At every reboot I got a notification about expire/renewing license. The icon color turned to orange to underline the message. It confused me at start because I thought there was some bug/threat,some win-updates not installed or something wrong. I hope the warning for expire can be limited in v5. Its just annoying to get so many notifications for something (even if once a year) that isnt a threat but just a remember-thingie.
