Trying to remove a stubborn program (Avast VPN)

So Avast VPN has ended up getting installed on my laptop. I don’t know how, and I don’t want it there. I can’t find an uninstaller for it, and I can’t even figure out how to close the app so I can manually delete things. A friend recommended Revo Uninstaller Free for getting rid of sticky software, but I wanted to ask whether that’s a reasonable/good idea. I’m not terribly tech savvy, so I’m not really sure how to look this up in general. I’m running Windows 10 on an ACER laptop, Aspire E5-574G

Any advice would be appreciated, thank you.

You cant find the program in task manager? (either in the processes tab or services tab)

No, I’ve looked and can’t seem to find it.
