I have run a scan with PC Tools Spyware Doctor ( Full paid up to date version) today& get the Tagasaurus warning - CCTreeview .ocx is the file as reported previously by others. If I look at the Properties of the file and in the "Company" slot it says "Company ", not Pirifirm as the main file does, for instance. All other details look normal- is this the genuine article or has a fake been slipped in somehow?
If so it would be interesting to know how it got there and if not, why does the spyware programme find it and rate it as high risk.
I also intend taking this up with PC Tools and will post their reply ( if I get one!)
