Question : Problem: All oif sudden, connected but cannot access websites

Sometime in the last few days (not sure when) my laptop started doing something strange.  I can connect to wireless networks that i could connect to before and I can connect to my work LAN using an ethernet cable, but I cannot open any websites?  This is on at least 3 networks I used to be able to use fine.

when i ping google i get "Ping request could not find the host..."

when i ping 209.85.135.147 I get 4 "Request timed out." lines.  I get the same when i try to ping the default gateway.

i haven't changed any settings, only thing new is I switched from Norton to Avira anti-virus protection.

I ran a spyware scan (spyware doctor) and there were no infections.  I tried a system restore to last week with no luck.  What should I try?  Neither IE or firefox is working and my spyware program cannot run its update.

Answer : Problem: All oif sudden, connected but cannot access websites

ccCommon seams to be a norton product. I would try the Norton Removal Tool first.
