Well uninstalled 4 again for the fourth time,then check with registry mechanic.Reboot install the new SD5.0.0176 took like seemed ages to do,got to box installing components.Then after quite a long time got the main SD program window two boxes were red,And underneath said it was checking the system,now this went on for ages.So went and had my dinner,came back exactly the same but now everything frozen.So used task manager to stop all the SD processes and managed to close SD down.So reboot took ages to load,finally managed to open SD again but exactly the same said it was checking the system same as first time.Again could not get it to close down unless with task manager.Finally got it closed but by now enough is enough,so tried to uninstall.But could not so again had to use a third party uninstaller got 5 off my PC clean up with ccleaner and reg-mechanic.And reinstalled 4 all went perfect done update and rescan without any problem.Now running XP pro all updates SP2 browser IE6,have uninstalled ZA to see if that was the problem,and the only other security program I have is kaspersky 5 AV.
