I've been having this problem since March. This application or spyware or whatever it is appears in the taskbar. I usually see it when I start up windows and all the regular apps are loading like AIM and Yahoo Messenger. Nothing pops up. It just white with a blue line on top with no title and just disappears quickly. It reappears randomly after the pc is on for a while. But what annoys me most about it is that it will happen when I have something open and jump on top. I can't play Final Fantasy XI anymore because of it since I lose full screen mode everytime.
I've ran different anti-spy programs like eZtrust pest control, yahoo anti-spy, Ad-aware SE Personal , and spybot - search and destroy. I also have Norton Personal Firewall, and etrust EZ anti-virus. When I've ran eztrust pestcontrol, it always finds 2 things in the registry that reinstall themselves. Kazza, and Grokster. I don't know of thats the cause of the problem. None of this happened untill I installed my printer its a HP PSC 2355 all-in-one.
If anyone has any advice or suggestion I would really appreciate your help. I miss playing the game and I wanna get back into FFXI again.
