Got a recurring pop-up window with firefox logo, pop-ups disabled. some kind of malicious program
Recently some sort of male-ware has been popping up windows when I make a secondary tab or click on a news item or some such. Also getting a small ad video in the lower right corner. These appear to happen separately. I followed the steps set forth in your help section. Downloaded Malwarebytes, ran it, still having the problem. Reset computer to a prev date. Still having the problem. Pop-up window comes up with firefox logo in the corner. Takes too long to load, I generally close it before I can see what the heck it really is. Popping up a lot tho and really becoming a problem. Please help. Thank you Tracy Lilly

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of. I have realized that malwarebytes is on the list, but try others. If push comes to shove, you may be forced to either: A) (Do this first) UNINSTALL FIREFOX WARNING: THIS WILL DELETE ALL OF YOUR FIREFOX INFORMATION!!!!! THERE MAY BE A TROJAN HORSE HIDDEN IN YOUR FIREFOX DATA AS SOME VIRUSES TARGET SPECIFIC WEB BROWSERS!
B) Take your computer to a specialist. They will know what to do, because this seems to be a malware problem, not Firefox problem.
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.

Run several or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.
Hitman pro found a Trojan on my computer and fixed it. Running well now. Thank you very much
FYI when I tried to use the ESET online scanner, a window popped up to download and run the software. When I moved the curser to the download hotlink, an ad kept popping up to prevent clicking on it. Needless to say, I didn't use it.
Good news. But don't just stop with Hitman, use other programs also.
