Updating anti virus failure

Hi, and HEEELP! My AVG Free (which has been working fine for ages, and updating automatically) says theres an update but when I try to it doesn't. I uninstalled and then downloaded it again, and still the update doesn't work ..
Any suggestions? I'm using Windows XP.

 

Have you tried downloading the update and installing it manually?

 

I downloaded it (thanks) but how do I install manually?

 

Many thanks .... the file I first downloaded didn't work, but after updating all my spyware etc in line with MajorGeeks' recommendations (I've been lazy recently) I tried again from the AVG Control centre and it worked

 

Thank you

Thank you for the welcome, you sure do make people feel at home and that's very reassuring for semi computer literate ones like me!
