Have (or did) you another Anti-Virus installed in this system, if so what was it and how did you get rid of it ?
What other security based software do you have installed that also runs on boot (e.g. firewall, anti-spyware) ?
With that kind of delay there is most certainly something else going on with your system, some of the above or low powered system.
What are your system specs, e.g. OS, CPU and RAM ?
You could try delaying the Auto Update check:
- In avast6 you need to edit (using
notepad)
avast5.ini the
[InetWD] section of the C:\Documents and Settings\All Users\Application Data\Alwil Software\Avast5\avast5.ini (XP file location). Location for Vista, win7, C:\ProgramData\Alwil Software\Avast5\avast5.ini.
If you did a clean install of avast6 the folder names are slightly different, \Avast Software\Avast\ instead of \Alwil Software\Avast5\ other than that it is the same procedure.
- Broadband connections, add this line:
AlwaysConnectedWaitSeconds=120 and
AssumeAlwaysConnected=1 if not present (or edit AssumeAlwaysConnected=0 to AssumeAlwaysConnected=1)
[InetWD]
AssumeAlwaysConnected=1
AlwaysConnectedWaitSeconds=120
When complete save the changes, avast's self-defence module will ask for confirmation, etc. answer Yes.
The figure is seconds and the above equates to two minutes, you could try that and adjust upwards if required, 180, 240, etc.
