If you've updated or upgraded to version 19.7, your issues could be related to a DNS setting in Avast, especially as you are running Avast Premier Security (formerly Avast Internet Security).
That setting is
Real Site which, for me, seems to randomly turn itself off. Windows Network Diagnostics will report the DNS server is not responding or not found and no internet connection is available.
Fix is to
ensure Real Site is on or, if you hare having troubles updating the newest version after install because of no internet connectivity, and avast emergency updater, remediation exe, and/or overseer exe all cannot connect because there is no internet connection, this workaround is as follows:
- Open Program and Features and navigate to AIS
- Click on Change
- Box will now say 'Checking for install conditions...
- Allow completion and close the dialog box
You should now have an internet connection to browse websites...temporarily. It will drop off shortly but the network will still show as connected. That was odd...
For some reason, 19.7 Real Site default setting is set to off, and when that happens, no internet connection will occur.
Not something readily found as I've always had Real Site set to on in all prior versions of AIS. Just turn Real Site on and you'll be good to go.
Also seeing licensing issues, Avast is reporting no license even tho I've purchased a multi-year license with 606 days remaining. Even tho the migration to Avast Premier Security is said to perhaps take weeks it already has done so. I put the licensing issues down to the migration not being done as smoothly as it should be, my licenses still show as valid. Perhaps the licensing servers need to be updated a little more quickly?
Note that the GUI still says Avast Internet Security too.
