Avast treats MSI Afterburner and BRSTM website as malware

I have an R9 290 that has been running hot in my computer and I tried installing MSI Afterburner to make a custom fan profile, but Avast blocked part of the installation. Afterburner doesn’t start with Windows because of this and I found this out moments before my R9 290 went into the critical range. This is not the first case of Avast finding false positives for me. It identified MSI Afterburner as malware on my second desktop and caused similar issues there. I mod Super Smash Bros. Brawl and sometimes I want to add custom music. There is only one site that holds a large storage of BRSTM files (A custom audio file made for Smash which is notable for its ability to loop) from many games and Avast has been blocking that site for months now (BrawlCustomMusic.com). Finally, I mistakenly upgraded my drivers to AMD Crimson and then downgraded back to Catalyst Control Center. Avast tried to intervene when I tried installing Crimson, and once again when I tried to install Catalyst. Every single time it interfered, I had to disable Avast’s shields to continue with whatever I was doing. Is there any way to get Avast to ignore BrawlCustomMusic.com, Afterburner, and my drivers? If by any chance, could they look into these false positives and fix them?
