I've been advising those seeking to Clean up factory bloatware
or Clean Reinstall Windows 7
to avoid any installed Google apps and especially Google Updater as these are pernicious spyware which track your searches and paste ads everywhere you go based on what you search.
And it's getting creepier: After mentioning in an email yesterday that I am going to use a gift card at Olive Garden for two separate lunches, I have been getting big display ads next to my inbox from Olive Garden. Creepier yet is that the items displayed are for the amount of half my gift card which is what I told the giver I plan to spend at lunch.
You don't have to be paranoid to see that this is some of the creepiest Big Brother activity the web has to offer. They apparently can now parse your text to find out what you're planning then paste ads based on your day-to-day plans.
I've got no installed Google apps, no Google pages (including Youtube) which I remain signed into that I'm aware, so supposedly they shouldn't be able to track me unless they've planted a cookie. I clean the cookies and the ads remain, everywhere I go, ads for what I've been searching or even discussing.
Since we know they scan the forums in real time, I wonder if they draw their bead on me here and have associated me with my other email and searches.
