The PS3 Trojan identifies itsself as an Unknown Disc but there is no disc inserted. Trojan COMPLETELY fries the BIOS in the PS3. This can also be used in PS2 and PS4 (as it was made for PS2-PS4). The trojan deletes data from other system files and games (such as the lbp sample game). It then ends a important system process which causes an "Tampered Client" Restart error and then the startup is the same thing but with rainbow changing colors and then it lags to a bsod screen. In PS2, is a different story. In PS4, It's patched because the system is WAY MORE protected from the virus. And after the virus is ran, It cannot be ran again.
