There is a kind of virus that spread thru pendrives. Once you plug in your pendrive into an infected computer system, you will see the following messages:

"New hardware found"
"Installing hardware"
"Your hardware is installed successfully. Do you want to reboot your computer?"

At first I was wondering why do I need to reboot my computer. When I checked the pendrive, I saw these (hidden) files in it

F:\ms.config
F:\rm
F:\AUTORUN.INF
F:\infrom.exe

Updated antivirus should be able to detect and clean all those files. Too bad my computers in the lab are not connected to the Internet and they do not have the updated antivirus database. All the computers are infected.

This virus is said to spread itself thru pendrive. If you plug in your digital camera into the USB port of an infected computer, I am sure the virus will copy itself into the digital camera. If only the media card is infected, then we can easily format the media card. But if the virus alters the system of the digital camera, then it would be a havoc.

Be careful of the pendrives.
