Have internet connection but can't use browser and several programs
On a Laptop with Windows Home Premium (Acer OEM) I have Windows Defender installed. Then downloaded AVG Antivirus around 1:st week of August. After the end of trial period AVG asked me if I want to upgrade to paid version or remain using free version with restricted options. I chose to keep the free version.
After som days Windows error center recommend me with a Flag to install a Antivirus product and offer a Web page with alternative product. I then wanted to try any other Antivirus product.
I decided to try Bullgard Security, downloaded it and then started installation. During installation Bullgard ask me if it first should remove previous security products and listed Windows Defender and AVG as installed or if I want them to remain in the system.
I chose to leave them and get through with the installation and Bullgard then want to restart Windows. During login and start up procedures Bullgard installation program started automatically. Its asked again if I want to first uninstall the other security product. This time I answered Yes and was then asked if I want to uninstall the other product one by one. It then started AVG uninstall program. If You use default options AVG keeps some minimal security detection and remains on the computer. In the tray You see the AVG icon, but because it was in the normally hided section I didn't see that AVG was loaded after the Restart of Windows.
Suddenly I couldn't reach any Web pages whit any browser, also I couldn't run installation program that download a part from the net before it could start installation so Bullgard couldn't bee installed.
Window says that I have Internet connection and You can use for instance Windows update and several programs update function. I first used AVG installation file to repair AVG. I then used normal Control Panel - Uninstall for AVG and AVG uninstall program started. I go to advanced options and chose to totally uninstall AVG and delete all user data. I also on another computer downloaded a AVG-tool that detects remaining AVG installation and files and then remove them. It couldn't find any thing.
After next restart the http protocol error still remains, I first think it was faulty DNS settings for the network adapter and manually set them as another functional Laptop. That's didn't help.
Even if I put in IP-address in the browser address field it says it can't reach that page and installation program that want to download parts from the Internet and for instance Spotify says that there is no Internet connection.
I have asked several support persons and friends with good network knowledge, no one have ever encountered this problem before.
I can of course save data and reinstall Windows, update Windows after reinstallation and once again install all programs, but if I could avoid that it would be nice!
Thankful for any advice!
I have portable version of SIW and can save and send report files if that could help any one to analyze the problem.
