Do not under any circumstances download an anti virius program called Cyber Defence! It just destroyed my computer! I am using my brother's computer to warn you. You can dowload it free. But then it will want you to upgrade and pay for the "whole" program. If you do not upgrade and try to delete it , it will destroy your computer when you restart. I have had one Tech wiz try to fix mine with no luck. Another one is going to try to save what was on my hard drive but he will be gone for a few day and is making no promises! I had a genealogical program on it with close to 10,000 names., besides my mail list and bookmarked favorities etc.
