I am not playing games but will be doing some video and image work, also a little music and a lot of documents.
also also: I use MS Office. which version is best? the $2C one that I think puts it on one computer and it stays on. The $60/year on that is a sort of subscription (?) what happens to my files at the end of the year?

I've used Avast for years, been great, never had a virus problem.
My family uses AVG, it's been fine for them, I quit using it because of the number of false positives.
Windows comes with it's built in backup software, that works fine if that's all you need.

Windows 10 has AV built in. Backup to a separate hard drive with plenty of capacity. W10 also has this facility. Or use Acronis which is very easy to use and very efficient. See links.

Kasperksy Total Protection. I've tried all the other virus protection software and all they do is slow down your laptop. Kaspersky is the only anti-virus software that does not slow down your computer.
