I have Windows XP and have been experiencing disrupted internet service for the past few days. When I start my computer and access IE, it works properly. However, about after 5 minutes or so I start to get "this page can not be displayed" or sometimes "this link appears to be broken." I constantly restart my computer so I can use the internet. I thought it was my modem or service. I've called my service provider several times and they said it's not their service, but it does appear something is blocking my access. I have Symantec Antivirus program. They suggested it was a firewall or something, but I did try to turn it off and it still didn't work. They also said to put my computer on safe mode? I'm not sure what to do next! I just want my working internet to work!
