NO! NO! this is a trojan.Horse on your pc you are the victim and the client or the person who has that Trojan on your pc can do vairus things like opening that chat window etc..
in fact has like 90% control on yaa pc so take care that is a scam it's a RAT (Remote Administration Trojan) i was using it and used to have over 800 victims take care .
Go Start press "RUN" type "msconfig" go to "startup" tap and look for any thing suspicious there like a program name "Windows Update" and it has no description so disble it from running on startup then do a scan with "MalwareBytes" if that doesn't work then PM ME i would help you .
