Everything runs fine for about 3 minutes, then the internet access and email slows down to a snails pace. The tool bar was changed and the url addresses in lower left corner of toolbar goes from url name to url number. I have to reboot and again it works for only a couple of minutes. I have used spybot, sysclean etc and they all say my system is clean of trojans and viruses. Any ideas on what is causing this and how to fix it. Thanks.
