Windows can't check for updates

[ledgemeister]

Hi All,

I get the message 'Windows can't check for updates' when I roll-over the Windows Updates icon in the notification area of my task bar. When I open up the Windows Updates window and tell it to update, it hangs indefinitely - I don't get an error message. Something similar happens with Windows Defender.

My computer is running very sluggishly and freezes regularly. Windows Updates has not updated since 4 Nov 2009, and Windows Defender has not updated since 19 Nov 2009. I am on Vista, and am running AVG, Avast, Malawarebytes and CC Cleaner. None of them have detected any infections.

Any advice would be very much appreciated.

Thanks in advance,

Marcos

You have two antivirus programs running! Uninstall AVG. They counteract.

Let us know,
