content: When I used to do residential computer repair, I once encountered an insane woman with an ancient Dell Optiplex. She had at least a dozen toolbars installed on her IE browser. I wish I could find the screenshot I took of it. I explained that her computer's slowness wasn't caused by a virus, but rather this multitude of crap running on her browser coupled with the fact she only had 256mb of RAM. She didn't want to get rid of any of the toolbars since they all went with various email clients and obsolete security services that she still thought were working.  "How am I supposed to block my pop-ups?"
