        Under C:\WINDOWS\Downloaded Program Files  where all of the ActiveX Controls sit ,most of them are listed as damaged ? However the app they referance works for instance one of the ActiveX Control listed is for Microsoft Web Update Control ,and when I go to the Microsoft Update site it will download and install updates ,another one of the several listed as damaged is Shockwave Flash Object another ActiveX , yet the Shockwave Flash Player on my system works when I want to view a video on it ?  My last PC had Windows Me and I had the same behavior on that O/S ? In the same folder as with WinXP it list almost all ActiveX Controls as Damanged ,when I asked about this is a PC Tech forum with that computer ,the only replies I recieved where from other members who where shocked that when they looked in the same folder I have listed above ,their ActiveX Controls where also listed as damaged . If I open the System Information Utility ,it will list them as Damaged also ?  Do me a favor take a look in your WinXP, Winodws Explorer,under WINDOWS at the Downloaded Program Files and let me know if any of you also have ActiveX Controls listed as Damaged ! Also anyone who knows how to correct this problem I would very happy to be told what steps to take ! Thank You in Adavance !
