Free / $77.99/yr at renewal
Avast's detection engine is genuinely excellent — AV-TEST has scored it a perfect 6/6/6 across protection, performance and usability in every recent Windows 11 round. Its privacy record is the problem: the FTC banned it from selling browsing data for advertising and fined it $16.5 million over data its Jumpshot subsidiary sold from 2014 to 2020.
