You're right. Once in a while, I encounter a user that has clearly given up. You can normally tell because they're running windows XP and their IE6 Crapium edition has 7 browser bars, some from defunct adware companies, and bonzi buddy in a corner...

You can't even say "only run software you bought from a bricks and mortar store" or "from reputable sources".

Java downloaded from Oracle has the Ask.com toolbar in the installer ffs !
