FOr reference, this problem applies to all my browsers: chrome, firefox, and safari. I also can't access the appstore anymore. Also for context as to why I even installed avast in the first place: some adware had managed to infect my computer (perfetnight) and made it play ads very loudly on my speakers. I've gotten rid of the initial malware (I hope), but now Avast is haunting my computer with a vengeance! does anybody know how to fix this?
