I have been doing business with someone on Fiverr. The person's help was really good, but I have concerns that they could potentially hack through TeamViewer. I never leave sight of my PC and I follow every click that is made with the mouse.
However, is there a way that someone can hack without my knowledge? Is there a way for them to control my mouse on their end and make it appear as if my mouse pointer isn't moving on my end?I make sure to completely log off and lock my PC after each session, however I am not sure how to check if my PC has been hacked without my knowledge.
