Recently I installed some random softwares from the internet and along with that some malware also got installed. I started getting " Your connection is not private " error in google chrome when I tried to open google.com .

When I checked the certificate, I found instead of Google's certificate I received "GoProxy untrusted MITM proxy Inc"certificate.

Then I checked my proxy setting. I found "Use a proxy server for your LAN" checkbox automatically checked and on clicking Advanced button, I saw my system was using 127.0.0.1 on port 8080 as proxy for both HTTP and Secure connection. When I opened http://127.0.0.2:8080 in my browser, I got the message "This is a proxy server. Does not respond to non-proxy requests"

Even if I uncheck the option to use the proxy, it automatically gets checked after closing the dialog.

My question is has the malware installed proxy server on my pc? How the malware has done this? How to resolve this issue?
