I borrowed a laptop from my friend who is network administrator, he installed a tracking cookie in my system and he knows everything I do on laptop. Every time I make any payment or transaction he calls me up for fun and ask to order extra stuff for him as well.
It was a joke earlier but now I am bit concern with my privacy. How can I find and remove the tracking cookie?
You don't have a clue whether your friend installed a tracking cookie or a keylogger or any other malware. Since he is the person to have full control of his computer, it could become very time consuming to find out how to which degree the computer is compromised. In my opinion, there is only one satisfying solution: Give him back the laptop and do not borrow it from him again. He might see it as fun, but you don't know what is the reason for him doing what he does.
