More Information

W32/AutoRun-DG is a worm for the Windows platform.

When run, the worm creates the files:

<System>\fool<random number>.dll
<System>\ieso<random number>.dll
<Temp>\<random characters>.dll
<Temp>\<random characters>.sys

These 4 files are also detected as W32/AutoRun-DG.

W32/AutoRun-DG spreads via removable drives by creating the file <Root>\autorun.inf (detected as W32/AutoRun-DG) and copying the worm to <Root>\n2.bat. The autorun.inf is designed to run the worm when the drive is connected to an uninfected computer.
