I took my computer to my Universitiy's ResNet to get it cleaned of viruses back in September of last year.. When I got it back, an icon showed up on the lower-right side of my dock saying that I need to install updates. However, it ALWAYS tells me I need to do updates (primarily for Microsoft Security Essentials). Even when I install these updates and restart my computer, the icon is still there, telling me I need to install new updates. Also, my computer now won't allow me to just shut down my computer. I have to shut down and install these updates always. These are my 2 questions:
1) If I don't turn off these updates requirements my computer is constantly telling me to do, can it screw up the installation of an external hard drive and/or screw up backing my data up?
2) How can I turn these constant updates off. They're very annoying.
