Basically it means if you installed it yourself in the location shown, don't worry, if you have never installed it (in that folder, usually windows\system32) then you should delete it and may be infected with a virus or trojan. Some trojans install a basic mIRC somewhere to receive orders for bad stuff, and thus it can be an indication for infection.
