It is. Seems to be pandemic at the moment (lol).First reports of this one according to sophos came right at the end of April. Not hard to get rid of though - could be done with a simple batch file if I knew that HP????.tmp wouldn't delete any genuine and valid files.
Code:
@echo off
echo *
echo * Ending task - dcomcfg ...
echo *
taskkill /IM dcomcfg.exe
echo *
echo Deleting trojan files...
echo *
erase %systemroot%\system32\dcomcfg.exe
erase %systemroot%\system32\simpole.tlp
echo *
echo *
echo **************************************************************
echo * About to delete all .tmp files in system32 with a filename *
echo * 6 characters long starting with hp (eg. HPwxyz.TMP) *
echo * WARNING!!! - any genuine file fitting This description *
echo * will be lost if present in this directory *
echo * *
echo * To stop now, close this window, else... *
echo **************************************************************
pause
erase %systemroot%\system32\HP????.tmp
echo * Finished *
pause
...that is, provided that the sophos advanced tab details the trojans activities completely.
As I say though, I'm a bit concerned that there may be a 6 letter tmp file beginning with hp that could be genuine for something. It doesn't deal with the autorun or browser helper object registry entries though, which HJT could take care of afterwards quite easily (file missing).
