Computer viruses can do many things to your computer that prove problematic. One of the more common issues you may experience is a loss of internet access. And there is good reason for this. After all, if a virus has found it’s way onto your system then it won’t want some pesky antivirus program or internet security suite removing it.
By blocking your internet access the virus will ensure that you can neither update your security software if you are sensible enough to have some installed, or download a security solution if you haven’t been proactive about protecting your computer.
There are many ways in which a virus can block internet access, such as installing unwanted browser add-ons and modifying the hosts file, but the one I’m going to show you how to deal with today is through use of an unwanted proxy.
Removing an unwanted proxy
1. The first thing to do is click on the Start button and then you click on Control Panel.
Next up, choose the option I highlighted above, Network And Internet.
2. From the next screen choose Internet Options.
3. A new window will appear, as seen above. Here you will need to click on the Connections tab and then on the LAN settings button.
4. If an unwanted proxy has been added you will be able to see it here. Under the Proxy server heading you will see a tick box that I have highlighted. If there is a tick here then you will want to remove it. Now click on OK and see if you are now able to access the internet once more.
5. If you do now have internet access then ensure that you either update your security software or download some right away.
6. Run a full scan with your antivirus program or internet security suite and follow any instructions given on how to remove the infection.
