Clean up rootkit / check firmware integrity
I'm in the unfortunate position of having my laptop hijacked. How do I know? The intruder told me. Initially he powered off my laptop 10-15 times (in a single day), then he injected (subtle) messages in my browser, revealing that he's looking at me through the webcam.
Anyway - format and clean install did nothing. He's still there, so it's storing code in expansion rom (firmware) or BIOS.
I'll attempt the following strategy:
Test integrity of all firmware and BIOS, and reflash those whose been altered.
I'm fairly technically minded but have no extended computer background. So, my question is: How do I do it? Any useful links for example?
