Hi there,

It seems somehow someone has uploaded and executed an application on to our web server that has resulted in it going ape.

1. Symptoms

  • DLL files reporting errors (in ASP.Net websites)
  • Internet Explorer fails to open
  • Firefox opens but fails to load any pages
  • Antivirus has been disabled

2. What I've tried

  • Attempted to install AVG, MalwareBytes and ClamAV. Issues either loading application or updating. (MBAM worked after changing the name, as chameleon failed)
  • Installed Spybot S&D but found nothing of interest.

3. Logs

a) Hijack This!

I have noticed that when killing any SVCHost.exe processes created by my user, "C:\Documents and Settings\Administrator\Local Settings\Application Data\nbjchubu\shxrrukm.exe" runs and recreates them.

FYI, this is a remote web server, I am unable to reboot into safe mode reliably.

I'd appreciate your help ;)
