my friend told me to install a program on to my PC and me being dumb listened.The progam was a rat (remote access Trojan) my friend told me that he removed my PC user from his rat program but I don't know if he can get back onto my account. He said the rat he put on my PC was crypted. I found out that resetting/deleting all data off of my drives besides windows will get rid of the rat. But now my friend said the rat he put on my PC seeps into the mother board and I don't know if that's true. He also told me to get rid of the rat I have to reinstall the rat so he can uninstall it and I don't know if that's true. I don't know how to get rid of it or if it's gone please help
