I've been on the phone with Norton, Microsoft and my ISP (Cogeco) about this issue and have ruled out that Norton Internet Security Suite 2010 and Cogeco are not the issue. Microsoft have been calling me in these recent days to figure this issue out and to help me solve it. My issue is when I'm browsing the myyearbook.com site (my profile, etc.), my network icon in the system tray shortly after says something like 'No Network Access.' Soft rebooting the machine puts things back to normal (having network/Internet connectivity). When this issue happens, it doesn't even recognize my routers or anything beyond the scope of my computer. I have all the updates for the OS. I'm an expert/advanced user so I know what sites to stay away from (ones with worms, trojans, etc.). I've run Malwarebytes in Safe Mode (no networking); also, Spybot S&D and Super Antispyware. Only cookies have shown up with no other threats. I'm able to access the site no problem with my laptop with Vista on it, so I know it's not a router issue. Any thoughts?
