The checking for servers has always been done via checking the OS version - so I find it rather unlikely that avast! 4 and 5/6 would behave differently in this aspect.
I remember the virus database updating process in avast! 4.x has been pretty CPU intensive, so that might be what you’re seeing. But honestly, whatever it is, there won’t be any 4.x program update to fix it, sorry.
