Daily Updates Avast 4.6 Home Ed

All my recent daily downloads have come from server: download(#).avast.com (67.19.XXX.XXX), with the exception of todays (June 30 05) which came from Server: www.iavs.cz (217.31.49.244). Am I being a victim of phishing/redirecting, or is this a legit avast server. Appreciate a clarification. Thanks.

Check the file servers.def in avast4\setup directory. It contains names of all ‘legal’ servers and iavs.cz is contained there.
