  • Smart Scan
    Smart Scan helps user identify security, performance, and network issues, and provides solutions to keep your digital life secured. It performs a virus and malware scan on your device, network scan to detect network vulnerabilities, and advanced issues scans that detect privacy issues and performance issues of your computer. NortonLifeLock recommends that you run the Smart Scan immediately after you install Device Security.
Smart Scan runs through multiple categories and performs the following scans:

  • Virus and Malware scan: Scans the areas in your computer that are most vulnerable to threats and eliminates the threats

Like bjm_ I used to be a Norton user, but their marketing behaviour and constant pop ups and difficulty of getting rid of it, turned me off Norton forever.

I will never use them again. There are better and more user friendly options around.

A little disappointed. I hope to see an update which can increase the level of protection. In terms of enhancing protection, the newly introduced Smart Scan feature seems to be of little benefit.

The following are areas where Norton should improve:
  1. Improve detection ratio for script malware.
  2. Improve the overall detection ratio by combining the Avira engine with the current one. Or even replace the current engine with Avira engine, which seems to performs better and has less false positives.
  3. Improve SONAR. According to Wikipedia (Sonar - Wikipedia (Symantec)), the latest SONAR is the 4th generation, which was released in 2012 and appears to be obsolete.
  4. Reduce the amount of time it takes to process a threat.
  5. Using Avira Protection Cloud and Symantec Cloud Protection (if possible) to tackle new viruses.
