When you boot up as quickly as you can achieve it open Task Manager and see what avast processes are running, the one that handles the auto update check is now instup.exe (not the old avast.setup), if you see that in the Task Manager it is checking for updates. That can add to the normal boot load making it slower for under resourced systems.
You can try delaying the update check in the avast5.ini file (set the 'I only connect to the internet using a dial up modem' back to always connected):
- In avast8/9 you need to edit (using
notepad)
avast5.ini the
[InetWD] section of the, C:\Documents and Settings\All Users\Application Data\AVAST Software\Avast\avast5.ini (XP file location)
- Broadband connections, add this line (if not present):
AlwaysConnectedWaitSeconds=300 and
AssumeAlwaysConnected=1 if not present (or edit AssumeAlwaysConnected=0 to AssumeAlwaysConnected=1)
[InetWD]
AssumeAlwaysConnected=1
AlwaysConnectedWaitSeconds=300
When complete save the changes, avast's self-defence module will ask for confirmation, etc. answer Yes. You can extend this duration if required (300 = 5 minutes).
