Thanks. Here are some screenshots. I don't know anything SecureLine. I installed Avast One Essential and Avast Security showed up on the VPN list. I went through the steps I've mentioned without success or understanding.
1) What I see at first is the screenshot that shows only Avast Security running.
2) If I turn on Avast, I get the screenshot with both Avast One & Avast Security running.
3) The 3rd screenshot happens when I disconnect Avast Security, but after almost exactly 1 minute it will restart, every time.
4) If I disconnect Avast Security and quickly go to the app & disconnect the Avast One VPN, I can connect the Proton VPN but after 1 minute Avast Security starts itself up so I get the screenshot of Avast Security running alongside Proton.
Assuming this whole problem was left over from a previous installation of Avast Security that's no longer present, I uninstalled Avast One, installed & uninstalled Avast Security, reinstalled Avast One. Same problem.
Do people with Avast One Essential also see Avast Security like I do?
If not, is this still an uninstall issue somehow?
Could it be a trojan of some kind?
Thanks.
P.S. I don't know how to put the screenshots inline above. Screenshot #1 is the one taken at 8.43 am. Screenshot #2 is 8.45 am. Screenshot #3 is 8.46 am. Screenshot #4 is 8.47 am.
