Inserting a USB freezes my PC because of Comodo Firewall

I have created a multiboot Live USB with linux distros on it and when i insert the usb my PC freezes. I have Windows 7 on my PC. I see the red light on the drive flashing but it is not showing in My Computer. If i disable all Comodo processes in task manager manually before inserting the USB, Windows recognizes and mounting it normally, but if i close the Comodo processes after i insert the usb it is still doesn’t work. I can’t even restart the pc i have to shutdown it forcefully.

Any idea why this is happening?

What processes did you close with Task Manager?
