You can have two anti-virus programmes on your computer BUT you should not set both up for real time scanning. Only one of them should be set to do that.
In fact there are two good reasons that one should have two av programmes.
1. There is NO one hundred perceny congruence at any one time between the databases of two av programmes.
2. AV programmes differ in their heuristic capabilities which are very important for detecting new malware.

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.

Most likely it is because your antivirus software has a firewall withch is blocking it, or the built in windows firewall is blocking it
