Avoid this company, they are selling your browsing data to third parties. https://www.vice.com/en_us/article/qjdkq7/avast-antivirus-sells-user-browsing-data-investigation They claim they are now winding down that business, however, they do it only because of the pressure after being caught, I cannot trust them anymore. Not recommended, trust is hard to earn, but easy to lose, they do not appreciate it enough.

Another negative experience, it keeps installing without permission. Avast seems to be very eager to get their hands on your browsing data.
