Has Zango cleaned up its act? Not according to PC Tools, which was sued on Tuesday by the adware vendor (formerly known as 180solutions). Zango alleges that PC Tools's Spyware Doctor delete's Zango's software without warning and that since late March, people who downloaded Spyware Doctor Starter Edition as part of the Google Pack are unable to install Zango. Zango's asking for at least $35 million in damages.Zango's complaint also objects to the fact that Spyware Doctor identifies Zango "as an 'Infection' engaged in a 'Malicious Action' that represents 'Elevated Risk.'"It sounds like that rating is maybe going to change in the next version of Spyware Doctor. Here's what PC Tools spokeswoman Magida Ezzat had to say about the lawsuit:We believe the proceedings are an attempt by Zango to influence ourreclassification process. Prior to the lawsuit we were well into anin-depth review and reclassification of the latest versions of Zangoproducts; Seekmo Search Assistant, Zango Search Assistant and Hotbarproducts which were released after the FTC ruling against Zango. Thesenew versions received a new classification of "Potentially UnwantedProducts" and are to be updated in the Spyware Doctor database in thenext few days.\u00a0We advised Zango of this imminent re-rating and we believe they havechosen to lodge these proceedings as a way to gain media attention ofthe review. PC Tools has a stringent review and classification processand will not be influenced or pressured into compromising this processregardless of the threat of legal proceedings. Zango's older products,including 180 Solutions Search Assistant, will remain unchanged at theirhigher threat levels and should Zango's newly reclassified productsrevert to previous behaviors PC Tools will not hesitate to reclassifythem to a higher level if justified.\u00a0PC Tools believes the proceedings are without merit and will vigorouslydefend them.When I called Zango about this yesterday, their spokesman Steve Stratz wouldn't say much except to confirm that there was a lawsuit and to direct me to his company's court filings, which didn't show up online until this morning. Why Zango wouldn't send me the filings is beyond me, but here's the complaint.As my news story indicates, Zango hasn't done much to convince its critics that it's really a changed company, and this lawsuit doesn't seem to be helping any.Sunbelt Software's Eric Howes had this to say, after looking at the filings:Looks more and more to me like they're looking to using the civil justice system to make up for funding opportunities that were lost once Zango became an internet untouchable...\u00a0 They're looking to squeeze some cash from PC Tools before the next round of layoffs becomes necessary.Sunbelt tested Spyware Doctor Starter Edition and said there is no evidence that Zango is deleted without warning. Looks like Zango has some work to do if it wants to make its case in the court of public opinion.
