I'm using BitDefender as antivirus (some features turned off is a must) - it scores 100% at av-comparatives.

For malware - Malwarebytes.
I'm not using firewall, because I'm behind NAT. If I need to filter something I just use hosts file.
Also on Windows - UAC turned off, and built in Administrator account enabled (using it). Win+R, cmd.exe;
Code:
net user Administrator /active:yes
