Pokertracker4 when ran through an Antivirus comes back positive for a Trojan. If you aren't aware a Trojan is something that gives the person who gave it to you full access to your computer and your screen and you'd never know it. They can then super use you and I would highly recommend uninstalling PT4 immediately from any device you own and never play poker on that device again.

I tried other software like Hold'em Manager 3, Pokersnowie, and Pokerstove all came back positive for trojans as well. Don't install anything on the computer you play poker online with. These PT4 people are scum of the earth and we can't tolerate this type of behavior as a community!
