Yes! I have this same problem! My husband also has it, so it's nice to know it's not just me and not just our computer. I read on another forum to download a spyware/malware removal program, which the consumer replied afterward that this helped, but it did not solve our problem, so I removed that program. When we got the computer, before we got online, I already had the McAfee Security system installed and running and we're vigilant about not allowing programs to download to our computer if we don't know what they are. Oh my gosh, just in the last few minutes of typing this post, I have had 5 different things pop up (two New Tabs, one "Open"/search window, and two "Bing" (search engine) suggestion windows). Frustrating!
We are using a Dell Inspiron laptop (not a mini-laptop) and it came with Windows 7. I am most frustrated that there are so many of us with the same problem and I cannot find an answer on the Microsoft help website. I'll keep checking up to see if anyone finds a solution.
