BEWARE THIS IS NoT A VIRUS BE CAREFUl PLEASE I had followed up on a search engine someone had recommended and ended up getting a search engine with many suggestive adult materials on it. It knocked out my home page, brought with it many popup ads of adult material, put folders into my Favorites folder, and my homepage was now that search engine. Everything I tried to do to knock it off failed. A popup ad came from Internet Explorer to put the updates on to take care of this problem and even then they continued. I just came from my computer store, and they said many people are having the same problem and sometimes it works its way into the hard drive, and only the computer store knows how to get rid of it for $50 - $60. I may try a couple of other patches from Microsoft before I give into that.
