Anyone have an idea of what the best lightweight antivirus is? It can be paid as I think paid will include more features. Thanks!
"Lightweight" and "More features" are sort of opposite. You can have leightweight with more features, but only compared to another with the same amount of features.
MSE is good enough, free and very unobtrusive. It might use slightly more RAM than some other solutions, but who cares about that.
