Unfortunately, virus and spywares are everywhere on the internet, sometimes I don't even remember which web sites I visited, or which one that had the virus or the spywares in it, when I had my first computer, I had McAfee free trail up to 30 days, I had no problems with McAfee so I brought cd of McAfee program until it expired then I haven't had any protection for several months then my husband download panda onto my computer, ever since then I had so many problems, so much spywares, virus, etc, it was very hard to get ruid of, casue there was just soo many of them and cause my computer not to work properly, and was going out of control, now I brought a brand new computer system, and use Norton AntiVirus, it works great, and now I know what would happen to my computer if it is not protected by any antivirus programs, that's why it's important to keep updating these programs on a regular basis or even when it's expired. Don't wait
