I used to use it. But one day the update screwed it up, and I can't get enough of it removed using the Uninstall to allow a reinstall. (The symptom is that when I try to install, I get an error message saying there are remnants of an old installation that must be removed before the installation will work). Since I use the free version, their tech support is no help. The problem must be some stray registry entries, but I've been unwilling to manually edit the registry since Norton's excellent registry editor doesn't work with XP. Any suggestions?
