Please read them. Hope that helps !

Tried them but with no success (VirusTotal show a treat in the first software). Malwarebytes succeeded to remove them with two tries and instead of restarting after the scan I turned off the PC and started it again.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

• Microsoft Safety Scanner
• MalwareBytes' Anti-Malware
• TDSSKiller - AntiRootkit Utility
• Hitman Pro
• ESET Online Scanner

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Did this fix your problems? Please report back to us!

I knew I may get something as I installed a program, which had Somoto warning during VirusTotal scan. I didn't expected it would be as serious. I hade probs with Somoto before but it didn't affect Mozilla that time. Now it went in the three browsers.

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 use the MSConfig program or the Autoruns utility to see which software and services are getting started (be cautious with disabling services).
