Avast detects URL:MAL when opening firefox 57.No issue with IE or Chrome, opera
upgraded to firefox 57 and get a redirect with it - sometimes blocked with Avast, sometimes not. " microsoft has noticed that you are infected.... "
other browsers are fine
uninstalling and will re-install clean to see if that helps

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
- Anti-Rootkit Utility - TDSSKiller (for more info, see this alternate TDSSKiller download page)
- AdwCleaner (for more info, see this alternate AdwCleaner download page)
- Hitman Pro
- ESET Online Scanner
Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista if you don't already have one. Windows 8/10 have antivirus protection built-in.
Further information can be found in the Troubleshoot Firefox issues caused by malware article.
