The company in this form lasted from its founding in 1982 until 1990, when it was acquired by Symantec (now Gen Digital).

The Symantec merger helped Norton Computing regain the market share it was losing to competitors, especially Central Point Software.

Norton Computing's revenues tripled between June 1990 and September 1991, and by November it appeared to have regained the market lead over Central Point.

In this year PNCI reached $5 million in revenues with Norton Utilities still bringing the largest parts.
