Thanks for all the tips, the first sentence is what I was looking for, opinions on software. I'm not a novice on computers, I'm careful what I click on. And if I lose data, it's my own fault, I rely on a popular cloud storage service for that, and occasional back up files (mostly pictures) that I store on one computer. I've been using Avast for quite some time, but just wondered what people's opinion on that type of software is. I'll try MS Defender on my new laptop when it comes, after I do a clean install of Windows.
