I have been using avast for about 10 years and just recently its not allowing certain games or gaming apps to work like discord chat for gaming and battlefield hardline. I added exceptions for both programs still didn't work. Uninstalled avast reinstalled and did the same for the programs that were being blocked by it. If I turn off avast shields they work fine but it leaves me unprotected. Called avast and they want to charge me money to tell me whats wrong EFF that I already pay a yearly subscription. So what is good out there that has a low impact on system resources and works well?
