Avast One Essentials is absolutely free to use and works great in Windows 11. Avast One Premium is the paid version, it has some extra features that you may or may not need. Essentials does have a quarantine for any malware or viruses it finds. Essentials is very easy to use, pretty much a set and forget type of program but does not have the option to choose which modules you want to install. But you can turn the firewall on or off in Essentials. Avast Free Antivirus has the option to pick which modules you want and I like it's GUI a lot better.
