I uninstalled again, reinstalled, and when it was done installing it proceeded to start leeching memory at about 10mb/second until it hit 3.8GB. Once it did, the amount of CPU time it was using went up to 13% and my BitTorrent download speed dropped from about 243kB/s to 10kb/s. I opened the avastUI and it told me something had turned it off and it was unsecured. I turned it back on and my RAM usage, CPU usage, and download speed went back to normal. I'm no expert, but it sounds to me like a virus got a hold of my Avast somehow and is hiding behind it on task manager... everything looks normal again but I'm still suspicious that somethings up
EDIT: RAM usage just randomly started climbing again a few minutes after I finished typing this. It's not done climbing yet but the problems obviously not fixed
