Many times I’ve seen random toolbars on Mozilla Firefox. It’s actually adware (ad-software). There are plenty of ways to remove these. One of the easiest ones includes AdwCleaner. You will need internet access for this. AdwCleaner does not require installation but it does require Administrator access.
Please note that you will have to save anything you are working on before you run AdwCleaner since it prefers to kill every running program while it’s scanning.
It also requires a reboot!
In our example, we have a Mozilla Firefox installation infected with Delta Toolbar and it’s changed also the home screen. We are going to use AdwCleaner which we will download from it’s official author, Malwarebytes. Please make sure you are always downloading from trustful sources.
Download AdwCleaner here.
AdwCleaner is a free tool that will scan your computer and efficiently removes Adware (ads softwares), PUP/LPI (Potentially Undesirable Program), Toolbars, Hijacker (Hijack of the browser’s homepage). It also features anti adware host that will help to prevent advertising software from installing on your machine. It works with a Search and Delete mode. It can be easily uninstalled using the mode “Uninstall”.
Click on the button:
When download is over, click on the file and run it.
UAC will ask for permission, you will have to say yes.
When AdwCleaner loads, you will have to click on “Agree” to go on.
Then click on “Scan now”.
You will have to wait a little until it loads it’s database through the internet.
When it’s done with scanning, it will load a list with its detections. Click on each of them and then click on Quarantine.
Now your Mozilla Firefox installation (and not only) is now clean from Adware!
