You did not give enough information to give a complete answer, but consider this:
The answer from anti virus software is that they delve even deeper into the OS, trying to be the first to be called. Now you install two programs, both fighting to be first. This sometimes leads to problems the one I will describe below.
Now lets try this two two anti virus programs installed
This is by no means the only reason why 2 AV programs would result in problems. But it is one easily explained.
Regardless of the cause, the rule of thumb is do not install two AV programs. If you want to install an other AV program, then first remove the old one. Reboot. Then install the new AV.
