Apparently, the US Air Forces wants to infect your computer with a trojan to use it if needed for cyberwarfare. You mean they haven’t done so already? Joshua Zelinksy looks at some of problems with their plans to create an army of zombie computers (yeah, sorry, zombie computers, not the other kind).
Update: OK, so I was wrong (see Joshua’s comment below), but it’s still a fun headline. 
Good news, someone tracked down the original USAF proposal. What they meant by civilian computers were computers in other parts of the US government. The proposal explicitly says they won’t secretly infect machines.
Interesting. I still don’t trust them
I critiqued this proposal on my blog (linked from my name on this comment), as well as on the Armed Forces Journal’s forum.
