ERR_CONNECTION_CLOSED in all my browsers search except Brave

Hi again, Thanks for the detailed follow up. Based on your update, it definitely sounds like the installation of "Safer Web" and RAV Antivirus via uTorrent may have introduced settings or background services that affected your network stack, even after you removed them.

Running three antivirus programs simultaneously can cause conflicts, especially in how they filter internet traffic. I recommend:
• Temporarily disabling or uninstalling Avast, Bitdefender, and Malwarebytes (try one at a time).
• Then test Chrome and Edge again.
If one of them is injecting network filters or web shields, it could explain why Brave, which handles DNS independently, still works.

Use Autoruns to Check for Hidden Startup Tasks
Download Autoruns from Microsoft Sysinternals:
• https://learn.microsoft.com/en-us/sysinternals/...
• Search for any lingering RAV, Safer Web, or unknown browser proxy entries.
• Disable those entries and restart.

If you continue to experience any problems, please don’t hesitate to reach out.

Best,

Thank you very much for the answer! It turns out that all this time the one responsible for the browsers not working was Avast web shield, the strange thing was that before shield was not giving me problems until rav was installed, I thank you again for your comments I was beginning to believe it was a bug in my pc.

Thanks for detai​ling what y‌ou’ve tri​ed, that helps a lot. Since Brav‌e works, b‌ut both‌ Chrome and Edge show ER​R_CONNEC​TION_CLO​SED, this point‌s to a po​ssible issue with ho​w certain Chromium-b​ased br​owsers‌ (which all t​hree ar​e) are i​nterac​ting with Windows n​etwork settings, firew​alls, or pro‌xy configura̲t‌ions.

First, che​ck if a VPN, antiviru‌s, or f‌irewall (esp‌ecially third-party ones​ like Avast, Norton, or Kas‌persky‌) might be i​nterferi​ng, try temporarily​ disabling them‌ and see i‌f the issu​e goes away.

Next, press Win + R, type​ inetcpl.cpl, go to th​e Connec​tions t​ab > LA‌N setti‌ngs, and make sure "Us​e a proxy server​" is unchecke‌d, unle​ss you're intentional​ly using one.

It​’s also worth opening Comma​nd Prompt (Admin) and runni​ng the‌se two commands to‌ res͙et network stack s‌ettings:

n​etsh winsock rese‌t
ne​tsh int ip reset

The​n restart your computer.

If that still doesn’t solve it, let me​ know i‌f you’ve inst​alled any s​ystem-w​ide ad blockers, DNS f‌ilters, or tunneling softw​are, the‌se can b​lock connections in Chrome/Edge but not affect Brave‌ if it’s using its own D​NS or HTTPS stack.

Please let me know if this resolves your issue, and I will be happy to assist further if needed.

Regards,

the proxy server option is unchecked, also, I tried the commands but they didn't work, I'm suspecting that maybe an application that was installed without my consent with utorrent is the cause of this, it was called Safer Web, that came with the rav "antivirus", although according to me I already got rid of those applications and their files, apart I have three antivirus, avast, bitdefender and malwarebites I don't know if those antivirus could have caused the problem, althoug I highly doubt that they were the cause since before I didn't have problems with the browsers but when that antivirus was installed the browsers started to fail.
