Kaspersky is a good suite can be heavy at times though and have slow scanning speeds... i also personally like avasts UI better than Kaspersky's new one. but ever since i switched i dont have any problems with slow downs and ive always seen avast great with prevention so clean machine you should be good

(if your not sure malwarebytes and hitman pro are great on demand not to get off topic) but yea i would even recommend just avast free if you dont want a paid solution.
