I became infected on my netbook running windows XP. Created the kickstart USB on my Desktop Windows 7 Machine - had to use the 64 bit version. The boot from the USB works, I get the Hitman screen - run scan - sometimes it hangs up, sometimes it runs through. Keeps finding a DisplaySwitch.exe file, and appears to Quarantine when it does not hang up. Finds it everytime, but when rebooting, the FBI screen returns. What am I missing - does it make any difference if computer is connected to the internet?
