Symantec's Norton AntiVirus is one of the oldest and well-known security application designed to protect your PC against malware of any type: worms, viruses, trojans, spyware, rootkits, phishing, etc.

It has a fast and easy installation process, but it tries to install software from third-party developers, and they are not required for its proper functionality.

It offers an intuitive GUI and several layers of protection making it a powerful security product. The classic antivirus engine is packed with heuristics and cloud detection and Norton automatically takes care of every threat it finds, except for the low-risk threats, that can be handled by user also, in case of detection.

Insight brings one strong community protection and with the help of more than 170 million Norton users, you can see which file is suspicious and why. SONAR Behavioral Protection steps out, when everything else missed a malware that can infect your computer.

Using advanced technologies, it will proactively protect you against unknown threats based on their actions. Identity Safe remembers, secures and automatically enters your usernames and passwords for you, so they can't be lost or stolen. Safe Web for Facebook scans your facebook newsfeed and wall and alert when it finds dangerous links.

Besides all these security tools, Norton incorporates advanced features to delete the worst malwares using Power Eraser or Norton Bootable Recovery Tool.

The product is pretty fast and does not negatively impact your system resources or battery life.
