So I uninstalled Avast! and turned on Windows Defender. I thought everything was fine until I tried a full scan and I got the error 0x8050800c suggesting that I install updates. Everything is updated. I looked up the error and then noticed I probably needed to use Avast's uninstall tool. My mistake. But, now that I already uninstalled it what should i do now? Everything says it's running fine, and it even completed a quick scan. Is it safe to use the internet?
