In the "Update (connetions)" dialog you can cross out for none, one or both of the choices "I only connect using a dial-up modem" and "my computer is permanently connected to the internet" and I find that a bit confusing.
My computer has a permanent connection (cable) BUT it's switched off most off the time. AND when I cross out for "permanently conneted" I don't get the updates when I turn it one and it connects (even if there are update).
Whould I instead choos "dial-up" or both - or none?
What effects does the choices have on the "check-for-updates" procedure avast! uses ?
I never tried the two options at the same time...
When permanently connected, avast! checks the update after 20 seconds it detects a connection (standard delay). New update will be tried in 4 hours. When you choose 'dial-up', the same 20 seconds delay and each connection will check for updates or, at least, 4 hours between two checks.
To remove the update error, the best thing is, open the avast4.ini file, go to [AAVM] section and add the following line:
SuppressUpdateErrorInfo=1
