Norton Internet scan did not detect a virus. I was doing a seach a few days ago and got a Mozilla Firefox update. I clicked ok and then a security warning popped up that said I had a virus and to call the number they listed. I could not go any furthur on Mozilla Firefox. I could not close out of Mozilla Firefox or do anything. .I had hard boot my computer to close out of Mozilla Firefox. When opening Mozilla Firefox again, the same thing happened and would not let me close out. Again, I had hard boot my computer to close out of Mozilla Firefox. To fix this problem I went to add and remove programs and put a check mark in Mozilla Firefox and then I saw options, I removed the 3 tabbed web pages and then closed out. I then went to Mozilla Firefox and was able to open and the page that had the warning of a virus was gone. I fixed the problem in Add and remove programs. I could have did a refresh but I did not want to lose all my book marks. Sometimes you can fix a problem by going to Add and Remove and just entering a check mark next to the program and it will give you options.
