Just run a full virus scan on your computer using Malware-Bytes
It found over 32 hidden Trojans on my computer.Or get one of the cpanel's and FTP host thing, and find proxy server php files from youtube, upload the php files to the cPanel's file manager, then make a webbrowser that uses the proxy server website you created. Also don't allow the link to be changed (no textbox for the URL), so that the webbrowser will most likely always use the proxy server.
