Online advertising turns even more mailicious. Banner ads get ignored? Try pop-ups. Pop-ups get closed? Try ads that look like the Windows user interface. Users too smart for you, not clicking on them? Try interstitial full-pagers. Users clicking past interstitials without watching the ad? Try layered ads that sit on top of content. Layered ads turning away users? Hmm... Try installing software that spies on users and displays ads dissociated from which web site they're viewing. Users not falling for the "install this software" dialog box, rejecting the download? Try bundling ad display software with popular free programs. Users getting wise to your trojan adware/spyware? Try using viruses, trojans and bugs in the browser to install software on the user's computer without their knowledge, kill their personal firewall, and give you control over their computer to install arbitrary software at a later date. That should get their business.
