As said before, replace SAS with either Windows Defender or any other free AV solution such as AVAST! Free, AVG, Fortinet, Sophos Home.
Also recommended to have at least a system image backup, making it easier to reinstall if you must. Data backup can be done via thumbs drive manually, but image backup you have quite a few solutions such as AOMEI, Macrium Reflect, Paragon etc, which all have both Free and Paid versions.
An adblocker extention will not hurt, such as Adblock Plus, Adguard or uBlock Origin.
Finally: if you participate in Malware Hub or play with malware, it is strongly recommended to use a fully virtualized system and not simply on your host.
