How antivirus software works
Antivirus software looks at the data—web pages, files, software, applications—traveling over the network to your devices. It searches for known threats and red-flags behavior to block or remove malware as quickly as possible.
What is malware?
Malware (short for malicious software) is a program specifically engineered to compromise the security features on your computer or mobile device to give cybercriminals access to your personal data and, in some cases, commit identify theft.
Malware sneaks in through a hole in one of your software programs, hidden in an online ad or disguised as a legitimate app you download.
