Well I'll be zanged!
For the second time, adware provider Zango has sued a software developer over its anti-spyware solution, this time targeting PC Tools and its popular Spyware Doctor program that comes with Google Pack. Zango, previously known as 180solutions, sued Zone Labs in late 2005.
Like its previous lawsuit regarding ZoneAlarm, Zango claims Spyware Doctor illegally removes Zango software from users' PCs without their express permission. PC Tools has rated Zango an "elevated" threat currently, but is in the process of reclassifying the software, perhaps to a more critical rating.
