Cons: slow, bugs you all the time, misleading updates,
Other Thoughts: Avast is trash and takes forever to scan. I got a virus and this useless program couldn't remove it but Malwarebytes removed it with no problems. I don't see why I have to register it and if you click the wrong button during one of many constant program updates it upgrades you to the full version. There isn't a day goes by without some kind of pop up bugging me.
