I have a slow modem and want control of updates so they don't interfere with occacionally important traffic.
I consider update important traffic.....
but you may get a reply from DavidR, he is also on a slow modem.........and he have 6 stars.....
Yes I'm on dial-up and there really is no need not to allow auto updates for the virus definitions and engine (the default setting), since avast uses incremental updates the actual size of the download is measured in KBs not MBs, so for a normal dial-up connection you shouldn't have any issues. I'm able to carry on working in the forum whilst this is happening, my only concession is to delay the update check for 10 minutes to allow for hopping on-line to collect mail or make a quick browse/search.
The program update is set to notify 'Ask' as this is likely to be bigger and you would only want to do that at a time convenient to you, e.g. not browsing/downloading something, etc. Having said that the last program update was still less than 1MB, see image of the last 5.0.507 - 5.0.545 program update.
