have you got any other security programs that you can run.And did you uninstall your last your last anti-virus using the proper removal tool.

If using I/E try tools.internet options.connections.Lan.And underneath Lan make sure use a proxy server is unticked.If it is ticked you may have problems.

Thanks for this, it now seems I cant download ( & install) anything, I get to the very end of installation & then it says, windows is closing,? please help, what have I got going on with this computer ? everything was fine until I downloaded Avast antivirus (which was so slow in use) , but that stopped working, so I uninstalled it, but the program files for avast will not uninstall, & I have used their own uninstaller, I can download any software to "save" but it wont install ?

Avast are having problems lately, especially with Windows 8 so they are trying to fix it. The last update caused XP to reboot to save Windows but was ok afterwards. You need to run Avast's removal tool in safe mode. Do you have the aswclear.exe file? If so run it in safe mode.

Try in safe mode with networking and see if it runs ok on that.

Try Googling "Windows Installer repair" I think there is a Microsoft program that will repair the installer. Worth a try !

Try a system restore to before you changed your antivirus.

rdave13 solution of system restore should work,

If not maybe run sfc /scannow and see if that finds any problems.

Sometimes when you cannot download or run security programs it may mean that your computer is infected.

So far you have not said whether your computer starts in safe mode or not.

If it does you can do a system repair and see if that finds any problems or a last good configuration.
