There is some weird problem.
When I start the laptop(it's using the wireless adapter for internet)if the wireless is not enabled,when the desktop appear and I start Process Hacker,I can see that the rest of the processes are started after around 20 second or more at once.
If the wireless is enabled,everything start immediately(no delay) and if avast is not installed,there is also no delay in both cases(have or don't have internet)
I think this also happens on my desktop pc but I'm not 100% sure(can't test right now)and I'm using cable there,not wireless(happens when the lan card is disabled or the cable unplugged or there is no internet)
The laptop and the pc are using the same WinXp and the same Avast Home version(latest)with the same settings.
