I have a functioning wireless/ethernet network connection, but no internet?

By thablitzreaper ·
I recently uninstalled a third party antivirus software that I stupidly downloaded called PC Tools. Right after the program rebooted my computer, I could not browse the internet, even though I have a functioning network connection, as you can see right now (I am on my ancient backup laptop). My newer laptop shows that I am connected to a network, but when I try to open any browser, nothing loads. It claims that I am not connected at all. What to do?

Most likely you have not completely removed the infection

Start off by Booting in Safe Mode and scanning the system with your AV program.

Then if that shows nothing you can use a Boot Disc one of the ones mentioned here and scan the system without Windows running.

Did you try running a repair on your internet connections in Control Panel?

Some antivirus software will install "adapters" that take over inspection of internet
packets, and if the uninstaller didn't remove this adapters link on your ethernet/wifi
then it won't allow traffic. Open Control Panel, then Network Connections and see
what is there. You may have to reinstall your ISPs details, using the connection
