My daughter came to visit and went on my computer using Internet Explorer not realizing that I use Firefox only. Ever since then, when I go to the computer or while I am on the computer, the Internet Explorer main page(Google is the default) comes up. I click on the Firefox icon, and could be just looking at the ESPN site as an example, and every 3-5 minutes, that screen pops up. I then have to "X" it out, and then I get the Internet Explorer error message, which says IE has to shut down, sorry for the inconvenience, and do I want the report, etc. This is incredibly annoying. I just purchased a "Registry Cleaner" and I even tried to delete the IE folder through "KillBot" but it wouldn't allow it? Need help please! Thanks!
