Ever since I've installed this software, it has stopped all the autorun virii that enters my system thru removable drives such as USB thumb drives.
You'll be amazed at how many digital photo places have infected computers. Stick your USB drive, or any external memory card, in there, and you're infected!

Oh, another good habit is to always open the drive and check contents by the context menu, rather than double clicking any drive, which then executes any autorun file on it. You'd need to have Show hidden systems on to see the autorun files.
