Internet Security Pro is a package of a) Antivirus, b) personal firewall, and c) ad/script blocking. If you disable b & c, no big deal. The antivirus proggies usually have to be disabled before playing any game, the auto-protects generally slow down gameplay. As for leaving yourself open for viruses, highly unlikely, unless someone has your PC IP & Port #. Even with those, it's still hard to hack your system without some sort of tool to ping your IP correctly.
