Cyber Defense Tip: Use a Pop-up Blocker
Pop-ups are Web browser windows that appear on top of another window, often to show advertisements. They can be very annoying and can really slow down your computer.
To help reduce the number of pop-ups you encounter, you can use a pop-up blocker. Pop-up blockers simply prevent pop-ups from displaying and can be a stand-alone piece of software, a plug-in for a Web browser, or built into your Web browser software. However, not all pop-ups are risky and not all are advertisements. Some legitimate sites do use pop-ups, so most pop-up blockers will let you know when they have blocked one and allow you to switch off the blocker for that pop-up or site if you need to.
If your computer is displaying pop-ups when you're not using your Web browser, it could be a sign that you have adware on your computer. Refer to Cyber Defense Tip: How to tell if your computer has malware to check for other symptoms and refer to Cyber Defense Tip: Defending your Computer from malware to learn how to protect your computer from adware.

Cyber Defense Threat: Cookies
Cookies are small text files that Web sites place on your computer to identify you and keep track of your preferences. This can make some sites easier to use because they will remember you when you return to the site, but cookies are also risky because they store information about you that cyber criminals might be able to find and exploit. Some Web sites can actually share cookies with other sites. These "foreign" or "third-party" cookies are especially risky because they may be sharing your information with a site that you've never heard of.
It's okay to use cookies now and then. To protect yourself, you should use as few as possible and also remove them from your computer regularly. Many sites will try to set cookies automatically, so you can set your browser to warn you before you accept them or to not accept cookies from any Web sites. You can use your Web browser's tools to remove any cookies you may have.
