Recently started getting extra add-ons, a warning of a virus, and cannot set my home page. I'm assuming that it's because of the virus, but am not sure how to get ride of the virus. Have Avast 4 Home antivirus protection. Not sure if this is the correct forum to post my thread. Whenever I go into internet options and type in my homepage address, it doesn't hold. It keeps changing back to aboutblank:,no matter how many times I change it back. Please help wherever you can.
