I have a laptop that connects to the internet fine. However, google.com, gmail.com, bing.com and Yahoo search bar are inaccessible.
I have searched long and far and have found nothing related to this issue. I tried various antivirus/antimalware solutions and eventually settled on 'Norton Security Suite' (360) which was provided for free by my ISP. Norton did find 2 trojans and another small piece of malware and removed all 3 of them successfully.
I thought it might have been an issue with the Hosts file after having rid of the viruses and malware with the problem still there. There was no hosts file so I did a search (Dogpile) and found a sample Vista Hosts file and placed it in the appropriate folder.
