The file in question is:
D:\Documents and Settings\xxxxx\Local Settings\Apps\2.0\0WD6149R.O6T\DJ564KAR.X60\psc.tray_ae4be581da5672a0_0001.0000_none_a045e3cc1db99f94\PSC.Tray.exe
I allowed if for now, but perhaps sidekick is doing things it really shouldn't.
From the Sidekick terms & conditions:
Notwithstanding Our privacy policy, which you can find here, when using the Software, Your username and password as well as the Kicks you have achieved, including the dates when they have been received and the name of the poker room will be transferred to our server, in order to guarantee the functionality of the Software.
I suspect that AVG somehow detected that it was sending information.
I'm really curious about what else Sidekick collects and sends.
