Why do I still see ads?
There are a few reasons why you might still see ads after installing Adblock Plus. Before checking for adware, we recommend that you try the steps in the Block all ads article, depending on your browser. If you still see ads, your computer might be infected with adware.
What is adware?
"Adware" is a blanket term for software that displays unwanted advertisements and/or other annoyances on your computer.
There are two types of adware:
1. Non-malicious adware
Non-malicious adware is software that hides on your computer and serves unwanted advertisements when you browse the web. The purpose of non-malicious adware is to generate revenue for its developer. Non-malicious adware is typically bundled with other software, so you may not be aware it’s installed.
2. Malicious adware (malware)
Malware is usually obtained during routine web browsing, oftentimes when you download a file from an unreliable source. The purpose of malware is to infiltrate your computer's operating system and collect personal data, such as passwords, credit card numbers, and pictures. If your computer is riddled with incessant pop-ups and/or windows that you can't close, there's a good possibility that you've obtained malware.
Why doesn't ABP block adware?
Adblock Plus blocks ads that are delivered from websites and/or their advertising partners. The only way to stop adware is to remove the software that displays it.

2. Install Adblock Plus

3. Keep your OS and software up-to-date
Keeping your operating system (OS) and other software up-to-date ensures you receive any security fixes included in updates.
4. Avoid clicking on unexpected pop-ups
Many malicious websites try to install malware on your system by making images appear like pop-up windows, or by displaying an animation of the website scanning your computer.
5. Only install software you trust
Some websites offer you software to accelerate your browser, to help you search the web, or to add toolbars that do things your browser already does. Some unwanted programs are also bundled in software packages. Usually, these programs gather information on your browsing behavior for the people who designed them. Make sure you only install add-ons, extensions, and plug-ins from your browser’s web store, and that you uncheck unwanted programs in software installation wizards.
