Spyware Still Cheating Merchants
Jamie found an interesting story about how Spyware is still on the move. It talks about how Spyware vendors are trying to clean up their image, but still doing fishy things. It breaks down several common types of spyware and some analysis of each.
I don't have a strong view on pop-up blockers. I often use Google Toolbar. But in XP SP2, IE's internal pop-up blocker works fine too.
One key insight: Pop-up blockers don't stop spyware-originating pop-ups. Pop-up blockers stop pop-ups that load through a web browser, i.e. as a result of JavaScript code within pages users request. But pop-up blockers do nothing to stop full Windows programs (e.g. spyware) installed on users' computers.
Then you didn't understand it. Blockbuster/Netflix isn't installing the spyware. They are the ones being robbed because of spyware you already have on your computer.
