Detection is apparently good as per AV-C, but god the UI/UX design of it is so moronic I've removed it after 10 seconds. And what a lengthy removal it was. You can just click UNINSTALL and it'll get removed. Oh no sir, you have to first remove like 6 dumb modules through Windows Programs and Features that each has its own entry and own uninstaller that takes several seconds to complete before you're allowed to uninstall AVIRA antivirus and then you can finally get rid of stupid launcher they have. And what a horrendous interface oh my god. Absolutely zero consistency, modules stacked upon modules, idiotic UI flow, like, I'd like to met the person who actually gets paid to produce this hot mess and congratulate him/her to achieve almost the impossible. AVIRA can have 100% detection with 0 FP's and I wouldn't want it anywhere near any of my systems, it's that terrible.

Bunch of clueless allegations about avast!... The promoting of paid features is dumb in my view, but that's how they are rolling now. The thing is, they aren't "viewing" your WebCam, they are just checking for presence of it and mentioning you have one and if you'd be willing to buy their paid product that has protection for it. It also accesses WebCam in paid versions because it has a module to block WebCam access for 3rd party unauthorized apps and if you have another software like HIPS, it'll probably alert you on that coz it's essentially doing a similar thing as avast.
They are also not reading your browsing history, it's monitored on local level using Web Shield. So, if you visit PornHub, avast! matches that with a local database of web addresses and displays VPN ad for their another paid service, because they see (on a local level) you're accessing page that might compromise your privacy and they offer you a product to help you with that. They mostly do this on high profile webpages with biggest user frequency (and PornHub is one of those for hm obvious reasons).
Again, I argue it's a bad way of doing it because like you here, people get weird feeling how avast! knows what they are viewing at actually makes negative perception instead of positive one. But avast! guys just wouldn't listen about it. I guess revenue to brand perception ratio is still in their favor for them to prefer their way.
