norton Antivirus has been around nearly as long as there have been Internet threats, but that doesn’t automatically translate to an excellent protection application. In fact, Norton Antivirus has had its share of ups and downs. In the past, the application was well-known for being a system resource hog that didn’t play well with Microsoft Windows and that wasn’t always accurate. However, times have changed, and Norton Antivirus has worked to repair that image. In the recent past, Norton completely revamped its offerings and added a host of additional features. We took the software for a spin, thoroughly testing the service, so read on to see out complete findings.
Norton Antivirus still uses the Windows malware definition engine to power its security offerings, and those virus definitions are updated multiple times a day—as needed to stay effective against new threats that pop up. However, in addition to signature scanning, Norton also has heuristic capabilities, which means it’s always watching and "listening" to files on your hard drive to spot any kind of unusual behavior. This helps ensure you’re protected against Zero-Day attacks for which a virus definition does not yet exist.
Most antivirus applications have both a full scan and a quick scan. Typically, the full scan is something the user kicks off manually after the initial scan conducted during the installation of the antivirus applications. Norton Antivirus works in the same way. There are several types of scans available—Quick Scan, Full System Scan, Custom Scan—and the application seems to default to the quick scan. In most cases, this will be all you will need if your antivirus stays active and updated.
