More Information

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

When run W32/AutoRun-EO copies itself to
<System>\drivers\spools.exe
<Documents and Settings>\<User>\cftmon.exe
<Root>\porno.exe

The following registry entries are set to run the worm on startup:

HKCR\exefile\shell\open\command
(default)
<Documents and Settings>\<User>\cftmon.exe \"%1\" %*

HKLM\SYSTEM\CurrentControlSet\Services\Schedule
ImagePath
<System>\drivers\spools.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
autoload
<Documents and Settings>\<User>\cftmon.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
<ntuser>
<System>\drivers\spools.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
autoload
<Documents and Settings>\<User>\cftmon.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
<ntuser>
<System>\drivers\spools.exe

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

W32/AutoRun-EO includes functionality to download code from the internet.
