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:

• MalwareBytes' Anti-Malware
• Anti-Rootkit Utility - TDSSKiller
• Microsoft Safety Scanner
• AdwCleaner (for more info, see this alternate AdwCleaner download page)
• Hitman Pro
• ESET Online Scanner

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

Also, if this has been happening since you downloaded Firefox, and you did not download Firefox from the Mozilla website, please uninstall Firefox and download a new copy at:

• https://www.mozilla.org/en-US/firefox/new/

Or if you need a different localization:

• https://www.mozilla.org/en-US/firefox/all/

Cory,

Thanks for your help I ran the MalewareBytes and it found over 2000 items. I thought I was good just with the Norton 360.

Thanks again

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.
