I see from another post you have xp, download TweakUI, and disable any drives you wish.You can then insert usb sticks,cd s etc,and any viruses will not auto run.You can then right click on the drive and scan with AV. To be 100% safe use Sandboxie. to run/play whatever is on cd,( right click on drive and choose run sandboxed ) http://ask-leo.com/how_do_i_really_disable_autoplay_in_windows_xp.html http://www.sandboxie.com/
