There was a very large AVG update recently that required a re-start but since then, updates have proceeded quietly and in the background. I would suggest that the large update failed to install correctly and it is trying each time to load this one - and failing.
I suggest that you download a new copy of AVG, come off the Internet, delete the current one and install the new copy. Re-connect to the Internet and immediately update your new copy.
Under no circumstances remain connected to the Internet while you are fiddling about deleting and re-installing.
Please wait for someone to agree with my advice before doing anything.
basically, don't worry! there are different versions of AVG 7; there are different OSs; and it depends which downloads you are comparing (and you may have downloaded the same update on a different day from your in-laws, so you can't simply compare days). Some recent downloads HAVE required a re-start; some have not.
