My antivirus keeps telling me that a virus is about on my computer. I delete it, and then ANOTHER one comes. I delete it, and another one comes. Windows XP says if the Automatic Security Updates are off, my computer is more prone to viruses. So, when I try to turn Automatic Updates back on, it doesn't work. There is a button saying "Turn on Auto Updates" but when I click it, nothing happens. In the updates setting, I have it turned on to "Automatic." But it still doesn't work. Help anyone?
