Windows defender is still a better option to Avast especially if you configure it right it is a beast!!!! Regarding Kaspersky..... The software like Avast uploads suspicious files that it does not (recognize or thinks is suspicious). It's not kasperskys, fault that an NSA agent loaded spying malware onto his/her PC and Kaspersky automatically uploaded it to it's servers as suspicious Avast would of done the same thing. That's just a stupid intelligence, agent's negligence. As long as you don't work for national US security you should be fine.... Liberals, just made a big deal of it because of the trump putin thing it's safe to use Kaspersky. All in all that US intelligence agent should have known better....
