Started to have big problems with my XP home copy. Most programs no longer working when selected. Internet pages that have any kind of security such as my bank will not load, even hotmail now refuses to appear! Help pages no longer load, system restore comes up with a blank screen etc. etc.
May be related to norton removal I fear. Installed AVG after I uninstalled my (2003?) norton however I have since found out this is not so straightforward. Since then I have removed it fully using the Norton tool as recommened here. Have also cleaned up the system using error nuker, tried system restore in safe mode...nothing!
