What Firefox locale (user interface language) are you using and what is the language in the Windows 7?

A possible cause could be a problem with the profiles.ini file

  • Windows: %AppData%\Mozilla\Firefox\
    C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
  • Linux: ~/.mozilla/firefox/
  • Mac: ~/Library/Application Support/Firefox/

If you have software like Advanced SystemCare that might reset some files to older versions to protect these files against changes then check the settings or uninstall this software.

You can check in "Windows Control Panel > Programs" for recently installed programs to check if any suspicious software shows up.

  • Control Panel > Programs > Programs and Features > Uninstall or change a program
  • Click the Installed column to sort by this heading

If this only happens when you reboot the computer then this can only be done by other software.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.

You can use the MSConfig program or the Autoruns utility to see which software and services are getting started, but be cautious with disabling services.


Do a malware check with several malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
