Adware maker Zango is tired and sick with having their "software" removed from computers by PC Tools, makers of the popular Spyware Doctor software, without due notification.

Representatives from both Zango and PC Tools confirmed that Zango had filed suit against the antispyware vendor. However they declined to provide details on the lawsuit except to say that it involved a dispute over the way Spyware Doctor rated Zango's software.

In a statement PC Tools said, "We believe the proceedings are an attempt by Zango to influence our reclassification process. Prior to the lawsuit we were well into an in-depth review and reclassification of the latest versions of Zango products," PC Tools said. "We advised Zango of this imminent re-rating and we believe they have chosen to lodge these proceedings as a way to gain media attention of the review."

This suit is pretty essential to the industry; it could settle on how forceful anti-spyware makers target adware on computers.
