For the past few weeks, I have had a Java popup come up more than 80 times. It comes up on almost every site I go to and its always requesting that I update Java. I have tried many suggestions, such as searching my control panel, deleting extensions off of Google Chrome, and I have run both Norton quick scans and full system scans but nothing has been found. It's staring to drive me crazy and its making my laptop almost useless to me. How do I get rid of this virus?
