Hello, Yesterday I happened to notice that advertising.com had invaded my computer and sucessfully loaded seven zip files without my knowledge or assistance. I noticed this when I checked my cookies after I had received one of their pop up ads with the following message. "Your computer is currently broadcasting an Internet IP address. With this address someone can immediately begin hijacking your computer." The way that I see things it was advertisng.com that was the hijacker and although I was able to delete their cookies easily enough it took a great deal of time to get rid of the above ad which was imbeded in my desktop wallpaper. My question is that I'm curious to know how this occured as advertising.com has been on Spyblaster's list for some time now and until yesterday Spyblaster had been very successful in keeping this and other annoying intruders away. Many thanks.
