Re: spyware detection/removal
The machine saying "Releasing spyware" on login is like a murderer wearing a shirt that says "I'm about to kill somebody". It's not going to happen, because that would just be plain dumb.
Frankly I can't say I believe this story, but if anybody suspects their computer has been messed with by somebody with malicious intent, they should reinstall the operating system.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
