If you have the Brave Browser installed on your Windows devices, then you may also have Brave VPN services installed on the machine. Brave installs these services without user consent on Windows devices.
Brave Firewall + VPN is an extra service that Brave users may subscribe to for a monthly fee. Launched in mid-2022, it is a cooperation between Brave Software, maker of Brave Browser, and Guardian, the company that operates the VPN and the firewall solution. The firewall and VPN solution is available for $9.99 per month.
Systemd “enabled” services are literal symlinks… whenever a target runs, it tries to start also all the service files on its “wants” directory.
You can literally enable any service for next boot by making a symlink in
/etc/systemd/system/multi-user.target.wants/(or whichever other target you want it to run on) as root (and installation scripts are run as root).ln -s /usr/lib/systemd/system/whatever.service /etc/systemd/system/multi-user.target.wants/whatever.serviceThis is actually very close (just tested and confirmed it). I somehow stand corrected about requiring manual enablement but this is just using the package manager to do the dirty work for you.
However the program itself cannot write into those directories without root permissions. You still have to allow your package manager to do this with root permissions as mentioned.
