Thank you all for taking the time to reply, good vibrations to you, and to....
A good security program, a secondary on-demand scanner, tertiary resources, and full engagement - check, check, check, and check!
Cleanup: Breach protection (anti-everything); search and destroy (when malware infiltrates)
Maintenance: For example, Windows Administrative Tools are in alphabetical order. But does it make sense to defrag and optimize before doing a disk cleanup just because of their listed order in the menu?
Real-time protection, on-demand scanner, regular backups, scheduled defrags, regular restore points, CCleaner (sans reg cleaner), MBAE, Unchecky. Sounds quite manageable. I've been told multiple times that I have a dry sense of humor so PLEASE don't misconstrue this little asides, k? I had to laugh because your reply is exactly consistent with everyone I've talked to. They run down their list (all pretty consistent with yours, by the way), but nobody ever just stops there! Everyone appends a similar caveat (some are more important so do those first), followed by statements I find akin to a type of confusion we all felt the first time we got busted lying to our folks about anything (everyone does it differently and in no particular order)! If some are more important, and everyone does it differently, then perhaps I should accept that importance is relative to the person instead of the machine. I think your reply tells me I have been asking the wrong question.
