I'm also having this issue. This is the second time. I uninstalled Avast the first time and it was fine. Windows 10 is up to date. I even have Cortana and all of the location, privacy stuff disabled. I decided to take another shot and download Avast again a couple months later. And now I'm having the issue again. I can't even uninstall Avast because it freezes on the first part regarding "aswNdisFit." I'm not sure what to do. I have school stuff on here to do and am freaking out a bit. At this point, I just want Avast gone so I can use my computer again.
