I hooked up my PICKit 2 up to a circuit (just a MCU) to test out it's logic analyzer functions. When I hooked up VCC and GND I got a message from windows that said "Power Surge On Hub Port" I then double checked my circuit and everything was ok. Hell it was working fine awhile ago when I was programming it with no changes in between. Shouldn't the device have stopped such a surge from reaching the system? I'm abit worried about the fact it didn't.

Sounds like you have a short. Try hooking the vcc and gnd wires to a multimeter and check you have some measureable resistance.
If that's not it, you should state what is connected to the hub, and if it is powered or not. It could be you are using an unpowered hub and the total combined usb devices is using greater than 500mA

actually it's connected directly to a usb port. I don't know why it says Hub.

If you have multiple USB ports, you may have a hub internally.

There's always one or more root hubs on a motherboard or expansion card.

I know but shouldn't the PICkit2 have some kind of protection to stop that. Kinda abit nervous I disassembled the circuit just as a precaution as I couldn't see what was wrong with it.
