This is a note to self:
When Combofix crashes on or before stage1 or stage2 a Trojan.Vundo and/or a Rootkit is present in system32 and is terminating the combofix process causing a crash dump.
- Install and Run Spyware Doctor with Antivirus and configure it to scan for rootkits. Register Spyware Doctor and then run a full scan. Fix anything it finds.
- Run a rootkit detection with GMER for a second opinion.
- Re-Run the latest version of ComboFix in regular mode.
