Won't comment on the the antivirus and firewall because you created a separate thread for that. Malwarebytes is good, but I would recommend supplementing it with Zemana AntiMalware, or even Crystal Security. Both have portable versions so they don't take up system resources in real-time. Do clarify what adblocker you have instead of just typing "yes" (EX: ADGUARD, uBlock Origin, Adblock?). I'm not an expert in the backup software department, so I'll leave that to others more knowledgeable. You have Windows 10 Pro + Smartscreen, so you have that going for you. Maybe consider a system cleaner like CCleaner, Privazer? Not required, but it's good to clean the system once in awhile. Again, we gotta sort out that real-time protection soon because that's your first line of defense (see my post in your other thread).
