What role does antivirus software play in helping protect your devices? Originally, antivirus scanned computer files and looked for patterns known to match computer viruses.

Today, the best antivirus engines use multiple methods for identifying known and unknown online threats, and antivirus is still a foundational component of security software.

Antivirus is file-based protection, and after a virus attack, having virus-infected files on a target computer or mobile device is one of the main ways online threats remain on that device after the initial attack.

Because of this, file-based protection will always be instrumental in helping detect, neutralize and remove viruses.

Someone else who uses your device might not be as careful as you. Having antivirus and security software for your computer or mobile device gives you protection against many types of malware that might not be easy to spot.
