Norton 360 automatically downloads protection updates regularly and secures you from all types of viruses and unknown threats.

In addition, Norton 360 monitors your Internet activities to protect your computer from the Internet-based threats that exploit software vulnerabilities.

You can also manually run the following types of scans:
* Quick Scan to scan the possible virus-infected areas of your computer
* Comprehensive Scan to examine your computer thoroughly
* Custom Scan to check for software vulnerabilities, backups, and disk optimization

Running a Quick Scan

Quick Scan helps you to scan the possible virus-infected areas of a computer that are often targeted by viruses and other security risks. Because this scan does not scan your entire computer, it takes lesser time to run than a Comprehensive Scan.

Running a Comprehensive Scan

Comprehensive Scan thoroughly examines your entire computer for viruses, spyware, and different security vulnerabilities.
