Zango has sued PC Tools over the way that Spyware Doctor rated Zango's software. PC Tools says that the legal efforts are an attempt by Zango to influence its re-classification process. PC Tools, which ships with Google Pack gives Zango an elevated threat level rating.
According to Infoworld, Zango wants $35 million in damages, because Spyware Doctor removes Zango's software without warning users that it will be deleted.
Infoworld claimed Zango was formerly known as 180solutions. In November it paid $3 million to settle US Federal Trade Commission charges that its software was being installed deceptively on PCs forcing them to endure pop-up ads.
