I am very security conscious (does it show?) and don't want an antivirus ruining things!!! I will block the unnecessary connections and only allow tup to connect when I want it to! I suppose I can add Avast's many IP ranges to a network zone in my firewall, block it and reenable the Web Shield. Thanks for all the detail, ady4um, I absolutely agree Avast should change that. I thought the only files that do not go into the Temporary Internet Files folder are streaming videos, is that not so? I do not understand why Avast.exe or AvastUI.exe need to connect to Avast's servers when it is not updating and even after it has just updated. I tried blocking AvastUI.exe and Avast.exe with my firewall and could still update by allowing tup.

The sites it is connecting to are all owned by Avast, the majority are in the following IP ranges: I'm afraid I do not understand the first reply, but it sounds like that would block my connection completely if those settings were there and I do not use dialup. That extra option would give the user more control so to adapt Avast to more different situations. to avoid the 'checking' for available updates too when in 'manual' mode. make it work as the current versions are in 'manual' mode or, At least, there should be an additional option, so to either: I hope that for Avast 7.0, the 'manual' (NOT 'ask') update will mean avoiding to even check for availability, unless the user 'manually' checks for updates. (In this case, the actual check is still valid, because without it, you wouldn't be asked).Īlthough nowadays having a security tool that can't update its database from the Internet would be strange, there are certainly some situations when you want to avoid from Avast trying to connect, even if it is just for 'checking' the availability of updates. It 'checks' for available updates, and when it finds them, Avast asks you whether to apply it in that same moment. The 'manual' setting is only stopping Avast from actually applying the available update. When you set it to manual update, the 'checking' part is still done (don't ask me why, because I still think it shouldn't check when in 'manual', but that's the way it is).

From those times that Avast actually finds an available update, if you set it to automatic update, it performs the update. Some of those checks are negative (no update available).

Besides the answers you already received, I want to add a little detail.Īvast checks for available updates every 240 minutes (that's the default).
