What is malware?

Malware is short for "malicious software." It includes viruses, spyware, and other malicious programs that hackers install on your computer, phone or mobile device without your consent or knowledge.

These programs can cause many different problems on your device, including making it crash completely. Spyware can be used to monitor your online activity. Criminals use malware to steal personal information, send spam and commit fraud.

What is spyware?

Spyware is a type of malware that spies on you and gathers information without your permission or knowledge.

Spyware can collect almost any type of data, like internet surfing habits, user logins and bank or credit account credentials. Some spyware can change your computer — installing software, changing settings, redirecting browsers and slowing your internet connection.

How to defend yourself against malware
