Can someone please tell me if I should turn off my Windows XP Firewall when using avast Internet Security (paid version - don’t know if that matters)? I’ve seen some comments in this forum that say you should turn off the Windows firewall and some that say you shouldn’t. Also, is it okay to run Malwarebytes with avast Internet Security? I want my pc to be protected, but I don’t want it running at a snail’s pace.
