Sorry if this kind of question isn’t allowed here, but I’m at my wit’s end. VB randomly started launching on startup about 2 weeks ago (on EndeavourOS) and I can’t figure out why. There’s no shortcut in ~/config/autostart, it isn’t in the KDE startup apps list, and I can’t find anything virtualbox-related with systemctl either. There’s also no setting in the VB app itself. WTF?
Looks like you need to change the session restore settings in KDE. It’s the virtual box GUI that starts up?

Your viruses installed themselves a Windows virtual machine to run properly?

To successfully automate a VirtualBox VM to start at boot time, we must ensure we’re running VirtualBox version 5 and above.
By default, after installing VirtualBox, the vboxautostart-service unit file should exist in the /etc/systemd/system/ directory.
Alternatively, for systems missing the vboxautostart service, we can create a custom systemd unit file that will contain our configurations to run VirtualBox on boot. systemd is a system and service manager for most Linux-based OSes.
Didn’t see you mention the autostart-service, and the article is recent enough that maybe it was added as part of an update?
Try to exclude it from being restored on KDE startup. There could be something running in the background that keeps getting saved and restored. Go to System Settings, System, Desktop Session, put virtualbox in the ignored applications list. You can also just choose “Start with an empty session” and then relog to see if that stops it from coming back, then you’ll know if this is causing your problem or not. Good luck!
I was feeling good about this one, but that didn’t work either.
Bummer! What’s its parent process? Maybe that will hint at something.
I’m not sure what you mean by this, sorry! My Linux expertise is limited once I get below surface level.
Well hey, welcome to the Linux club :)
Unlike Windows, in Linux every process has a parent except for PID (Process ID) 1, which is the init system. You can run a command like
ps auxf
and you’ll get a tree of all your processes and you can hopefully see what spawned VirtualBox.
