Just a simple question if you have Security Awareness: Advanced, then why do you need three real-time AV's?
Most users who have Security Awareness of Advanced, can get by with just a simple AV like MSE or none at all.
It is not wise to run more then one AV in real-time. I have seen this actually cause infections on systems because one will conflict with the other when both at the same time will try to block an infection causing both to lock up and the malware then can escapes both and infect your system. In order for an AV to do its job, it needs no interference form another security product.
Besides that I feel sorry for the system that tries to load of of these processes in its memory, it is just not good for a system. You might as well have a few malware running because they will probably do less damage then what three real-time AV's would do.
Thanks.
