So... I've been using avast (both free and premium versions) and recommending it as an IT professional since back when it was ALWIL. I've put up with some of the not so great UI changes over the last few years that have really obfuscated the location of critical things such as the quarantine chest. Changes like these happen, and while mildly inconvenient at first- you do get used to it and it's fine. But honestly, the deluge of popups advertising avast premium for free version users is not okay, you want to stuck it on the ui, nag them about it when they're using it- sure, that's fine, but intrusive advertisements from something most end-users install to get rid of and prevent that very same kind of symptom is absolutely unacceptable. I will not be recommending Avast anymore, nor will I be using it myself. (Granted other solutions have always been better, but Avast was once a good company which is more than I can say for some other competitors with higher market-share.)
