Error code: PR_END_OF_FILE_ERROR I see this error with every website I try. I first noticed the problem after I installed ZoneAlarm, I've since uninstalled the program and tried many solutions, but nothing is working. None of my other web browsers ate connecting either.

Hi adamcpht,

Sorry to hear you are having issues connecting to the internet. The Secure Connection Failed may be caused by different reasons.

Is Zone Alarm completely removed from your computer?

If you haven't already, you could try starting Firefox in Safe Mode to see if that solves the issue.

To do this :

  1. Open your web browser
  2. Click the hamburger 3-bar menu in your web browser
  3. Click Help (towards the bottom)
  4. Click Restart with Add-ons Disabled
  5. Click Restart
  6. Click Start in Safe Mode (not Refresh Firefox)

Hope this helps.

If other browsers are affected as well then it is likely that something got wrong with removing ZoneAlarm (i.e. some components are still active) or something else is wrong with the internet stack (LSP) and you may have to ask advice at a Windows oriented forum on how to troubleshoot this.

You can boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
