Hi,
the same issue here with command line closing by X with AVIRA 13 Antivirus from homes32
Closing with "Exit" works.
BSOD: 0x0000008e (0xC000005E, 0x00000000, 0x8D8B4C44, 0x00000000)
Tried on VM and different PCs.
It doesn't happen without Avira. Avira itsself works without any trouble.
Best Regards
