Prevent Virus in USB from Spreading
USB drives have become the favorite path for viruses. As usb drives are becoming more and more popular, the viruses are also becoming popular. Have you notice that every time you insert your flash drive it will pop up a window which presents an option on what you will do? That my friend should be CANCELED!

Autorun Pop up for USB Flash Drive
Do not be fooled by this pop up especially if you are not 100% sure that the flash drive is virus-free. The reason why you should not use that window is because most of the virus are using that one as the trigger point. One you will click on that, the virus has a way of entering into your system.
Another way of propagating the virus is by double-clicking the flash drive when opening the My Computer window. Do not be lazy and instead right-click on the removable drive and choose Open or Explore.
Another way to avoid triggering the virus, use the address bar to access the removable drive.
If you want to permanently turn off the autorun pop up, you can configure the windows registry.
Open notepad and put the following code in it
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\Autorun.inf]
@=”@SYS:DoesNotExist”
and save as a .reg file (for eg: autorun.reg). After that double click that file and a window will appear and ask for the confirmation to save it to registry. Click OK.
You can also download tweakUI (a small application from Microsoft for customization of xp). Install it.
Run tweakUI, and from the left side, under the MY COMPUTER, choose “autorun”, Select the type option.
Untick the option, Enable autorun for removable drives. and select ok.
Done.
