How to stop firefox from opening new ad tabs when clicking on a legit link or even a blank space?

Question

This has been going on for months now in every computer in my house. If I go to any legitimate website and click on a legitimate link (not and ad) a new tab opens up to either a bogus virus warning, an ad page, or a survey. I have reset Firefox to default conditions several times without any results. I have Kaspersky Internet Security 14 and ran a scan (no virus found). I have Hitman Pro and ran a scan again without results. I have also ran Malaware Bytes, and Norton Power Eraser to no avail.
Mozilla has to do something about this as it is happening to may users.

Answer 1

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.
