I used an ADWARE remover program on my lap top and after I was done I can no longer ACCESS the internet on that computer. The internet is FINE and working correctly on all other devices. It says there is a problem with the DNS server. It's windows 7 and chrome and IE both don't work. Please help, I've been trying to figure this out for ages.You could try by setting the DNS to a static config, leaving your IP to dynamic and gateway to dynamic:

208.67.222.222
208.67.220.220

More info at this link for your OS:

*I use OpenDNS for my DNS bouncing off of MIT DNS Servers 250 miles away from me.

Also go into command shell and run the FOLLOWING:

IPCONFIG/ALL

and verify that you have an IP, Gateway, and DNS info that looks correct. If you see

0.0.0.0
or
169.x.x.x with x being any value

Then your not going to be connected to internet and there is a greater problem. Usually IP's are 192.168.1.x if using the default router config DHCP etc. And if 192.168.1.x then the gateway IP is usually 192.168.1.1
