I am on windows XP, the boot up is fine its when its loading avast on the desktop screen im 90% sure its avast which is taking so long? The icon spins around for a long time, a long time is about 1-2mins, before my computer is ready to be used. I also have Sygate Firewall as well. But thats all i have. It could be the windows applications and avast is checking them while they are loading i dont know.
