I agree with Mike, a solid statement. Although I must admit, I'm more of a "feel for it" person. Technically, facts are most important. Emotionally, what you feel is right, is right. I'm still, at age almost 57, trying to find a balance. The MOST important is to have one AV running. What comes with Windows today, I find reliable, 'cause so many here use it. Personally, I'm still hung with Avast, but I have the paid-for-version, Avast Internet Security. I had a short experience with Windows 10, it was impressive and assuring, however I went back to Windows 7, as I got no sound, and DVB Viewer wouldn't get any video - I didn't have the time to solve issues, I decided to wait until they have resolved problems. Pragmatism is a key word when doing your job, and earning a living.
