What is malware?
Malware is malicious software, often installed and run without a user’s knowledge. Examples include keyloggers, viruses, exploits, adware, and spyware. Malware can disrupt a device’s operation, collect and transmit private information, gain access to administrative level computer functions, and display unwanted advertising.
How does Malware work?
Malware is often embedded in or disguised as non-malicious files, and can run as a script, executable, active content, or some other form of software. The purpose of malware can be anything from a prank to a tool used to steal financial information.
Malware can be guarded against using up-to-date antivirus software, a firewall, and a VPN.
