Something that many security researchers have feared has indeed come true.

Threat actors have integrated a critical exploit taking advantage of a popular communication protocol used by Windows systems, crippling thousands of computers worldwide with ransomware.

With thousands of threats being generated every day, many of which are unique, one-of-a-kind threats that are served up to uniquely infect your particular system, it is possible that you have come into contact with a threat Norton does not yet recognize.

In addition, some malware is designed specifically to disable Norton's anti-virus software.
