Here’s an example. I removed avast via the uninstaller on a relatives computer, it made it laggy as hell. I restart after as the uninstaller demands, but it was still there.
The official Avast Uninstall Tool, the tool to use when the included uninstaller didn’t work.
The official uninstall tool didn’t work either. I ran it in safe mode, like it said. Didn’t work, either, but it removed some stuff, and finally let me delete some things manually. Ran it again in safe mode after that, finally seems to have removed everything.
Anyway it’s a great example of if a company doesn’t know what they’re about, windows has no process to recover from that. Window’s process is identical to a Walmart employee saying. “I dunno, man, contact the manufacturer.” Genuinely, its usually enough, but when its not, there’s absolutely no recourse.
