Background audio ads even with no tabs open

This is driving me nuts. I have searched for answers, but none help.

I get random audio ads even when there is only a new tab open in Firefox 15. Started with "Congratulations, you won", but today for example, I get an ad for Disney World. Its incredibly annoying.

Happens at random. I could have several in 5 minutes or none for a day of browsing.

I auto clean my cache after each session. No proxies. Does not seem related to any plugin. Have created a new profile.

There MUST be a way t stop this. Anyone have good ides?

Thanks.

Sounds like malware or adware embedded in an extension.

For external malware, you may want to run some third party scanners to supplement your regular security software. These two tools are highly regarded:

Malwarebytes Anti-malware : http://www.malwarebytes.org/products/malwarebytes_free

SUPERAntiSpyware : http://www.superantispyware.com/

For bad extensions, I suggest disabling ALL nonessential extensions, then restarting and running Firefox for a few hours that way to see whether the problem goes away. You can gradually re-enable the useful ones until you stumble across the culprit.

orange Firefox button or classic Tools menu > Add-ons > Extensions category

Thanks, but I have tried most of this and more. There is something else going on. A Google Ad cookie, something. HiJack this and Spybot find nothing. I have run malwarebytes previously with no hits. And read MANY threads on this but no luck. It really does drive me mad. Last ad was for Condoms...

Try to delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

You can use this button to go to the Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Show Folder

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

See:

You can also try to reset Firefox:

Thanks Cor-el, but as I said in the first post I did try a new profile and hence new sessionstore.

I ****think*** I found the culprit. Not 100% yet, but Yahoo's Finance pages run ads without having to click on them on the foreground or background and might even be persistent after closing the tab. Whether this is all of my problem or not, do not yet know, but its definitely a contributor.

If this is all of it, is there a way to block ads from just Yahoo pages?

Thanks.

Content should not play after you close a tab. Is it possible there are one or more off-screen pop-up/pop-under windows?

Most ad blocking extensions let you create your own filters, so presumably could be targeted to an individual site.

You can do another malware check with some malware scanning programs on the Windows computer that you haven't tried so far.

You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.

If using various malware scanners does not fix it or if you are blocked from installing those scanners then ask advice at a forum that specializes in malware removal.

I agree it should stop when tab closed. It DOES stop if the plugincontainer process is killed and Firefox remains open. Maybe that is another clue.
