I had to get my mother a new computer, which brings her into the era of XP from 98, (now that we are at the end of xp and soon will have a new OS) Anyway I need to download the new version of NOD for her new computer. Been out of touch with the tech of computers, not to mention these boards. Since I havent been in touch with technology lately. Im a little lost on what to download. From the eset downloads page I find the following NOD32 Ver2 For windows 2003/xp/ - 64-bit For windows NT/2000/2003/xp So which do I download. I bought her a (cough,cough) Dell Dimension 9150. It says its a Intel Pentium D Processor 820 (2.8GHz, 2MB L2 cache, 800MHz FSB) with Dual Core Technology. and uses the Intel 945P chipset. So how do you know if its 64 bit or not? and which version of NOD do I install?
