Did you find a USB memory stick and are afraid to plug it in? (good)
Does your friend want to insert their (possibly infected) drive into your computer?
Panda USB Vaccine may help...

Panda USB Vaccine is a free antimalware solution designed to protect against this threat. It offers a double layer of preventive protection, allowing users to disable the AutoRun feature on computers as well as on USB drives and other devices:
Vaccine for computers: This is a ‘vaccine' for computers to prevent any AutoRun file from running, regardless of whether the device (memory stick, CD, etc.) is infected or not.
Vaccine for USB devices: This is a ‘vaccine' for removable USB devices, preventing the AutoRun file from becoming a source of infection. The tool disables this file so it cannot be read, modified or replaced by malicious code.
This is a very useful tool as there is no simple way of disabling the AutoRun feature in Windows. This provides users with a simple way of disabling this feature, offering a high degree of protection against infections from removable drives and devices.
