No Internet (avast! Internet Security)

Hello,

I am encountering a big problem. When I open Chrome, it says my firewall or antivirus software wrongly thinks google chrome as an intruder. I’m using Windows 7 Ultimate OS. After I install AIS, I rebooted my computer and I had no internet connection. Although, it’s very weird. I have a router and other people can connect to our internet. I can use my iPad to connect my I can’t connect with my computer. However, only the browser does not work. I can use skype and play online games. I don’t think my internet is the problem.

I tried turning off all the shields of AIS but still no internet.
I tried uninstalling AIS but still no internet.
I tried installing AIS then uninstalling by using avast! Removal Tool but still no internet.
I contacted my internet service provider and they said their service was working so I’m guessing it’s my computer that has problems.
I tried flushing my DNS but still no internet.
I tried turning off my firewall but still no internet.

I do not have any other antivirus software other than avast!.

This has been like this for days. Please help.

Reinstall the network drivers.
It should reset things.
Let’s see if that is solving the problem.
