Currently using Windows 98SE, looking to replace hard drive and install Windows XP Professional. Using trend internet security which I downloaded - have original download on external hard drive so I can reinstall on new drive. Need to know what files I need to also back up from Trend programme i.e. pattern files and where do I find them all, there are so many different types of checks,e.g. damage cleanup, antispam etc? Will the download with OS Windows 98SE work on XP?
