Following trademark infringement

If you've infringed a trademark, the stuff you used to do it can be confiscated. So what happens if you've run pirated software on a computer (which would be infringeing the trademarks associated with the software), but because its in your own home no-one really knows about it, would it then be illegal to use the computer, because if you'd been found out it could've been confiscated?
Or would it only be illigal if you'd actually been to court and told to hand it over, etc.
Like my last question, this is more a matter of the technicalities of law, rather than any really pressing need

If you are using pirated software at home, there is no trademark infringement. Trademark infringement requires "customers" to be "confused" about the origin of the product -- if you are not selling pirated software, there can be no trademark infringement.

Copyright infringement, well, that's a whole 'nuther story, as they say...

Hmm. Well... it may be a whole 'nuther story, but does the same still apply?

Actually, thinking about it, I was under the impression that there would be trademark infringement because the software would probably contain trademarked logos, etc. But never mind about that.

I was just wondering, if there was the possibility that the equipment would be confiscated if the infringement (of compyright/trademark/whatever law) was discovered, would its continued use actually be illegal if a court hadn't yet ordered it to be confiscated (because the courts didn't know about it)?

Thanks for any information

Err.. don't know if I should be bumping this but... does anyone have any information please?
