An App installed by someone phishing won't delete

I am having a similar issue, but I never installed the Connectwise or Screenconnect myself. I know someone has been gaining access to my laptop. I am getting a fake windows update in progress screen but I can see the mouse moving on the screen. I am getting authorization codes I did not ask for. I have followed the steps to delete the programs, but it is not showing in my programs for me to delete it. I have the Screenconnect icon in my tray that continues to say "waiting to connect or connecting. Any ideas on how to delete it when I can't find it.

Hi! You did the right thing by stopping the call when you realized it was a scam. Since ScreenConnect is a remote-access tool, it’s important to fully remove it to prevent further access.

Immediately disconnect from the internet (unplug Ethernet or turn off Wi-Fi) until you are sure the software is removed. Change your Microsoft account password and any other sensitive accounts you accessed from that PC, then uninstall ScreenConnect

1. Press Windows + R, type appwiz.cpl, and press Enter to open Programs and Features.
2. Look for ScreenConnect or ConnectWise Control Client.
3. Select it > click Uninstall.
4. If it refuses to uninstall, try again after restarting your computer in Safe Mode: Hold Shift while clicking Restart > Troubleshoot > Advanced Options > Startup Settings > Restart > choose option 4: Safe Mode.
