This is the major query i saw in our forum , USB Devices like i-pod,pen drives e.t.c; brings viruses/worms which are bad since it disables a lot of features as well as it ruins memory the slows down the whole thing. It disables much of the removal process like Windows RegEdit.exe, MsConfig.exe and also TaskMan.exe. Variations of these also disables your keyboard during normal booting, floods your disk with virus files in the root directory and also the windows directory and some also floods your directory with Folder looking icons that is an executable..

So heres my tip in avoiding this:

1st: Always make all files visible like system and also hidden files with their extension shown.
Go to Windows Explorer > Tools > Folder Option > View
* Enable Show Hidden File
* Disable Hide Extensions for know file type
* Disable Hide Protected OS files.2nd: Never Use the Autorun functionality in Windows
whenever you put a disk(flash, memory card, usb drive devices and other form of removable drive) it is always a practice to scan it first. but to avoid being the first to be infected by a wild one, always use Windows Explorer to browse the files. Use the left side(Folder Window), to browse the files. Whenever you see an autorun.inf file, delete it! remove the disk and insert it again to avoid clicking it.

3rd: Always update Virus database!
