Windows Defender and Windows Firewall should be turned on.
If you suspect that something has gotten past Avast and things are acting 'funny', simple run a scan with a program named Malwarebytes. It can be run along side of your antivirus program, does not scan or update unless you open it and tell it to, and is a good program that does pick up on things that slip through. It can be used regularly like once a week or once a month, or only when you suspect a problem. Most here probably do some of each: run it when we are bored or simply remember, and if something just does not feel quite right.
If you ever feel that you are beginning to run a bit slow but nothing shows up under any of the scans, just ask and we will offer some suggestions to clean out your system and get it running better again.

You have to be a little bit crazy to keep you from going insane.

The Windows firewall is not an antivirus like the other two and should be left on at all times unless you have an alternative firewall.

Normally you have only one antivirus in case they conflict, although I doubt Windows Defender will cause any issues. You can always temporarily disable real time checking in Windows Defender to see if it helps, like this:
Open Windows Defender from tray icon (right click) and you will see it in the Settings tab. Just uncheck it. If it is not the culprit put it back on again.

MalwareBytes, already mentioned, is good at finding issues that antivirus programs miss. You can get it here (green button top right):

Let us know how you get on and if MalwareBytes finds anything paste the log on here.

Always pop back and let us know the outcome - thanks
