ISSUE:

I lose internet connectivity with my browsers (IE & FireFox) without warning - happens at all times of the day (mostly during business hours - less at night). Email operations (check adn send via Outlook Express) still works but the browsers fail. Reboot eliminates the problem but it reappears later. It is not related to any specific web site (will happen at Cnet, CNN, ESPN, etc.).

Any ideas what to do? Thanks in advance for the help!

ACTION:

I've followed all the instructions in the sticky thread - have run numerous virus scans (Norton, Bitdefender, etc.), ad-aware, spy-bot, etc. Looks like everythat that could be troubling is gone but the problem persists.
