Changing the proxy address to 127.0.0.1:8080; Internet does not work

Hello.

I have a problem with the internet. I am using chrome browser and I get the message: "no internet connection. Proxy is not working properly or the address is incorrect". The same for other browsers, some display the proxy server address given in the subject. Initially, it happened once in a while, now the internet does not work at all. Unplugging and connecting the cable or starting the computer does not help. Similarly on wi-fi. I have read similar topics and I think you need to write a log to FRST. I attach scans in the attachment. I read that the problem may be instalshield, which appears to me.

I am asking for help and detailed instructions on what to do.
Greetings.

If you set the proxy to localhost, it is not surprising that you do not have internet. Well, unless it's the malware that sets something different.

Next to frst.exe, create the Fixlist.txt file with the contents:
