PSP and NDS Trojans

Im surprised no one has metioned the viruses that can brick a PSP and the NDS.
Theres only one virus at the moment for the PSP and two variants for the NDS
The psp virus deletes your firmware and the nds virus delete the firmware on your nds and flash card.

Some people trying to run "safe" "legitament" have had problems with their antivirus software. To get round this you will have to disable your anitvirus software. To protect your psp and nds update your antivirus software or an even easy method is not to even bother running homebrew on your psp or nds.
It aint worth the risk of bricking you psp or nds. Id stick to emulation on your PC.
