It used to be on Spywarewarrior's bad spyware list:
Note on XoftSpy: XoftSpy was listed on this page because of concerns with false positives (1, 2, 3, 4), questionable license terms, and the use of aggressive, deceptive advertising (1, 2), including exploitation of the name "spybot" by affiliates. Earlier versions of XoftSpy were also Ad-aware knockoffs. (There was clone of XoftSpy named SpyBurn, but that application is no longer available.)

Over the past few months, XoftSpy has taken aggressive steps to reign in its affiliates (who were primarily responsible for the unsavory advertising), revised its license text, and released a new version of XoftSpy (version 4.0) that addresses our concerns with false positves. Given these changes we can no longer regard XoftSpy as "rogue/suspect" anti-spyware.
