I have a new Windows XP Pro SR2 computer with NOD 2.7 Trial Version pre-installed by the computer vendor, Microcenter. NOD32 comes up when I boot, and goes into a loop where it asks me whether I want to do three updates, Yes or No, but no matter which one I answer, it repeats the update window. If I close the window, same thing, loops back. I can quit the program, but that is not a good idea when connected to the Internet. I did get it to update just once, so I have the August 21, 2007 updates. I could install the paid version, which I have in a box, but I could go with AVG, which I have always used until now. Reviews and messages here convince me that NOD32 is very good, but this looping business puts me off. Any advice?
