Knight Disk Virus!!!?

It started a few days ago. i gave some data to my friend on a pen drive. he informed me latter that the pen drive had a virus named knight disk (or dish...not sure) that his anti virus program (avast) detected.

he said it had a heart-like icon and had text written in Arabic or some similar looking language. i scanned my computer with my anti virus program- Kaspersky Internet security V.7. it showed no such result.

he got rid of the virus by formatting the pen drive. the same events were repeated again today, when i sent him another set of data on another pen drive. he again complained that the pen drive was infected by knight disk virus.

this time i searched for any program or file having the word 'knight' in its name in my system (hidden too), but found none. neither does my Kaspersky shows any virus threat when i use a pen drive.

how can i disinfect this virus when my antivirus program doesn't show any signs of it? is my computer infected or is it my friend's (which i have doubt)

It was actually meant to stop the spread of pen-drive viruses, but instead allows you to block/enable ALL processes, so it is quite clumsy.
