Now it looks like there may be something on your PC afterall. Apparently the DNS is working and the port 80 connection is possible. The IP address worked. But Google.com didn't. It's like there was an entry in the hosts file that caused it to go to the wrong place but OTL doesn't show anything.
Look in C:\Windows\SysNative\drivers\etc\ or C:\Windows\System32\drivers\etc\ Do you see the hosts file? If not you may need to set Windows to let you see it:
Open the Control Panel menu and click Folder Options.
After the new window appears select the View tab.
Put a checkmark in the checkbox labeled Display the contents of system folders.
Under the Hidden files and folders section select the radio button labeled Show hidden files and folders.
Remove the checkmark from the checkbox labeled Hide file extensions for known file types.
Remove the checkmark from the checkbox labeled Hide protected operating system files.
Press the Apply button and then the OK button and exit My Computer.
Now your computer is configured to show all hidden files.
Now that you can see the hosts file, look and see if you also have an lmhosts file. You should have an lmhosts.sam file but there is no need for an lmhosts file so delete it if you find it.
If that didn't help then:
Download and Save it then right click on the file and ExtractAll.
You will get a folder called HostsXpert. Double click on it and then
Right click on HostsXpert.exe and Run As Admin.
It will show you what is in your hosts file. Win Win 7 there is really nothing there by default but it will normally show you: 127.0.0 localhost in the right pane.
Verify there is nothing else there.
Click on Editing then
in the box under Add Line, type:
then click on Add Line.
You should see the stuff you just typed appear in the right pane.
Open a browser and see if it will go to google.com now.
Sometimes Firefox will use incorrect setting from IE. We can tell it not to:
In FireFox, (Tools or the Firefox button), Options, Options, Advanced, Network, Settings, check No Proxy then OK. Close Firefox and restart Firefox.
Clear the Java Cache by following the instructions onhttp://www.java.com/...lugin_cache.xml
You have AVG. Is that the free version or the paid version? (The paid version is supposed to have its own firewall so it might be something to look at.)
I've got to go to bed now.
