This question already has an answer here:
I was under the assumption that my IP address was hacked last night because of this movie website I was on. Thanks to the good people of “stackexchange.com”, I learned that they tried to con me by scaring me into buying a firewall for $500.
To make a long story short I gave the fake “tech team” access to my computer thinking they were helping they had control of my computer and ran a “diagnostic test”.. come to find out they were scam artist. How do I know if they still have access to my computer?
