Troj/Dloadr-AOO is a Trojan for the Windows platform.
The Trojan has the functionality to silently download, install and run new software.
When run the Trojan copies itself to <System>\msvcrt.exe and creates the following files:
<System>\xdrv.sys - (Detected as Troj/He4Hook-D)
\x.htm - (Can be removed safely)
The following registry entry is set or modified, so that msvcrt.exe is run when files with extensions of EXE are opened/launched:
HKCR\exefile\shell\open\command
(default)
msvcrt.exe ^%1 %*
