As a result of overhauling virus and spyware protection on my computer, I found that the Microsoft Spyware programme installed had expired. I therefore uninstalled and downloaded the FREE version of the latest - Windows Defender (Beta 2) X64 - which turned out to be the wrong version. When I tried to install I got "This installation package is not supported by this processor type". I now know that I should have got X86 (I have now and it installed with no hitch). My problem is that when I tried to uninstall X64 I got the same "not supported by this processor type" message.
How do I uninstall? Or is it not worth bothering with?
It's not listed in Add or Remove PROGRAMMES but is in My Documents.

I have AMD Sempron 2800+ processor, Windows XP SP2, AVG and VARIOUS other newly acquired security stuff.

I'd try CCleaner. It's free - voluntary donations are encouraged - and has very positive reviews in Download.com. Did it install in the first place, if not then just delete the file.I've now deleted the desktop icon and the My Documents icon - sent to Recycle Bin - Then deleted them from there. That's cleared all trace as far as I can see, but does that mean the programme is wiped from my computer?

I have CCleaner so I'll run that again.

Thanks for advice.try to find the file in program files then try to delete it...it doest work try to reinstall ur operating system....
