You mean the same company that bought PCTools and Xtree?
(And then closed both of them.)
From a QDGS: (Quick & Dirty Google Search)
Central Point - Makers of Pctools
CP aquired Xtree first, then Symantec bought out CP.
Xtree clones have flourished however, like Ztree and UnixTree.

You may recall they also bought out Delrina in the mid-90s
(Winfax, Talkworks, Wincomm pro, Cyberjack)
And Quarterdeck (Cleansweep, Crashguard)
and probably one or two others that I don't recall.
(not counting the earlier purchase of the Peter Norton branded apps)
Interestingly, Powerquest was founded by Eric Ruff, the same guy that
created Q-DOS and Optune IIRC. I remember a past presentation where
he remarked on his desire to never sell out Powerquest like he had to
with Gazelle Systems (his old company). But I guess times change.
