I have looked in add and remove programs and found this command program listed, and it wasnt there before the worst part is it wont let me remove it. my tray icons are all gone and instead there are little blue blocks taking their place. I'm running extremely slow. my os is windows xp pro laptop is a dell inspiron 6400. can anyone help me with this? please!
