Posted

I was infected by a virus (i can't remember the virus name). Antivirus removed it, but i think it changed some config file on FF, 'cause every time i try to restart it , i find it configured to use proxy 127.0.0.1:64727. I change every time the config, i also tried to change the config on the about:config and set network.proxy.type 5 , no port and no network proxy (so it's all on default) . I changed the config on the gui, i removed the config from windows registry ( IE and chrome start normally, with no proxy), but every time i restart FF i find the proxy config there. How can i fix it ?

I had the same problem.

Solution

Clear Virus First

-clear virus using either anti-virus or manually going into task manager and figuring out which processes are bad.

-If the manual way, go through each process in task manager and right click to "open file location". Depending on where it is located and the name of the process, you can google the process name online to see if it is bad.

-Delete the bad process file and as added security, create a folder using the name of the process so the file can't be recreated later. (example: If I had a virus "3dcr.exe" in folder c:\user, then delete "3dcr.exe" and create a new folder c:\user\3dcr.exe\ )

Fix Proxy Settings

-If your browser points an proxy server and you can't change the settings because every restart of firefox returns the settings back (even after changing in about:config or prefs.js or options>advanced>network>settings). The answer is to uninstall firefox with all its user preferences and the reinstall it.


  • I know it is a bit brute force, but it was the only method I found to work. Just be sure to save your bookmarks first.
