this one is very common virus thing i guess, affecting Pen Drives
virus-> Worm.Win32.Small.i
Trojan-> Trojan program Backdoor.Win32.PcClient.wi
My Kaspersky kicked the virus out, but the "double click to open" function was not working, so i had to format the pen drive, now the Pen Drive works good.
i gave the Pen Drive (with songs) to my friend, when i got back the drive, aila i got a virus & a trojan

, & know what my friend was using McAfee Internet Security

, still he's McAfee didnt detect the virus

, so ultimately he went for KAV loooool
