It is advisable for you to only install 1 antivirus software in one PC. If you happen to install 2 antivirus software in 1 PC and your system hangs, that is because the system is confused and the antivirus software is fighting for dominance. You should remove one of the antivirus and if you want to change to a different antivirus, you must un-install the previous one.
