If your software is collecting your digital information and then sharing it with a third-party without your permission, then it's spyware, a harmful software category that spans browser cookies, adware, Web beacons, and keyloggers -- to, perhaps, even your favorite software.


Thankfully, you can grab a spyware-monitoring app or extension to watch for and remove trackers and other forms of spyware.

Frequently Asked Questions

How to fight spyware?
Because it spans Web beacons to malware on your Mac, you need to take a broad approach. A browser extension like Ghostery can detect and block Web tracking tools to protect your data. And for a more serious infestation, turn to one of the anti-spyware tools we recommend to root out the malicious software.
What is spyware?
Although tracking your online and computing behaviors can be used for good -- sharing software diagnostics with a developer, for example -- when it occurs without your knowledge or consent, it's a problem. And while milder forms of spyware can take the form of adware or co-opt your browser to display annoying pop-up ads, more viral types can capture keystrokes or share financial information.
Does legitimate software spy?
Well, it depends on what you mean by "spying." Windows users were up in arms about perceived spyware activities when Windows 10 first shipped. Twitter recently shifted its privacy policies to allow it to share more information about you and your activities with advertisers. And reputable -- and disreputable -- websites track your online browsing and purchasing activities.
