Thank you all for the replies, think possibly made informed decision, and think gonna go with Avast Free, as it's more light weight than Defender, gave Defender a try on my main Desktop, and observed it using a lot of CPU and memory at times, despite I never messed around with VIrtual machines at all. Hopefully this is right decision now, I think it is more so than before I asked this question. Then again did use Avast Free since 2006 on old Desktop PC, this newer gaming system decided to give Defender a try a bit longer than i did in past
Plus while was doing some video encoding, CPU temp with Defender was going up into the high 70C range, imagine it was using alot of cpu during those tasks on main desktop.
Who knows i might give Defender another shot in t he future when 1903 releases or a future version after that
