You can install as many anti virus programs as you wish as long as you
don't run them simultaneously and continuously in the background. All virus
programs offer various levels of security. The default usually involves
some kind of start up scan and scanning in the background as programs
launch. Many users turn these features off because of the resulting
performance hit and deploy the program as a scanner only. You will have to
make sure any features like these are disabled and that you only run one
anti virus program at a time in order to avoid the problematic setup you
are suggesting.
