To use (and enjoy) Linux properly, you’ve got to “unlearn” several things including the bad habit of expect everything to “just werk”. If you are expecting to “double click your cares away” on Linux, then it’s (very) likely you’ll be disappointed.
With that aside, your best bet is to go for Linux Mint and not Arch Linux.
Not really a “anti malware” per se, but you can always set up a separate linux device (like a orange pi zero 3) and set it up as a network ad blocker with nextdns (which apparently it can be (also) a “anti malware” – which I haven’t tested if it is legit or not, but eh.).
