Is there any easy way (a program/app would probably be the best, but I don't think I'm allowed to ask for a recommendation on one [if one even exist] on these sites) to check whether any known remote access programs are installed on a computer (PC, Mac, Linux, etc.)? This would include things like LogMein, GoToMyPC, TeamViewer, ScreenConnect, RDP enabled, etc.
As an IT consultant, I'm often in the position of taking over support of new systems that have previously been supported by others (and who knows what has previously gone on with these systems prior to my arrival). As a result, securing them is a good first step, but since many IT firms use different remote access software (which might not always appear in the system tray, start menu, or add/remove programs), I thought some way to quickly assess the computer's remote access vulnerabilities and disable/remove them would be a useful thing to do.
Thanks!
