Have you tried doing a system restore to a time before the problem started?
I had spy-bot and ad-ware on my computer. I uninstalled them and now I can't access the internet. I reinstalled them hoping that would fix the problem, but I still can't get online. I have a broadband conx. According to the ISP the settings are set properly. When I open IE 6 the indicator on the status bar flashes rapidly, then it finally times out. I can't even ping the website. I've done an ipconfig release and renew. It shows the ISP info. Any ideas on what might have happened or how to fix it?
