I need to perform some task on a remote computer (like full scans, browse thow files, intall a software or a printer, stuff like that) what is the best, free and secure remote control software available?
Two very good applications are TeamViewer and LogmeIn. Both are free for non-commercial use.
Thanks for your answer. I downloaded TeamViewer after all. The website seems more pro.
It’s a matter of personal preference. Glad to help 
I have used ShowMyPC with great luck
