hi… i am also facing the same problems… avast unable to update to virus definitions 111109-0…keeps on showing downloading file:vps_32-632.vpx. and after sometime shows connection terminated even though am still connectd to the internet…am using windows 7 and the resource monitor shows avast.setup eating up most of my bandwidth under the network tab even while it is not updating. i tried reinstalling… but still no luck… cud there be a problem with their servers?
