Such malicious AUTORUN.INF files are easy to spot. Here’s what they typically look like:

Nice trick.Â Â eh ?
Now lets Disable AutoRun :Â
Disabling Auto-Run is something we think everyone should do, not only for security from viruses and spyware, but so you’ll never need to deal being unable able to listen to your music on your devices. Here’s how to do it in Windows XP.
In Windows Click Start, then Click Run
Double click “Autorun” the value is set to 1 by default, change it to zero.
If you can’t go with all this then you can try doing this :
From the start menu, click run and enter
Select ‘Administrative templates / System’
double click on ‘Disable autoplay’ in the right pane
Hope this keeps things a little under control
