Beware Of USB Flash drives
1.If you find a USB token in the wild, don’t plug it into your USB port as it could autoinstall software if your system is set to autoplay CDROMs.
2.Though many organizations’ standards call for disabling autoplay of CDROMs, you should check and set yours. To disable autoplay follow these instructions (for WinXP):
Open My Computer
Right click on your cdrom drive selecting “Properties”
Select Autoplay page and set each menu option to “Select an Action to Perform” = “Take no action”
Click Apply (you must apply each setting change one at a time!)
Repeat for each item in the list (alternatively ensure that all are set to “Prompt me for action”)
