i have the same problem. the icon appears in the tray but nothing happens when i click on it. i can remove it cause it goes to the white screen. i cant scan for viruses because its the white screen. i tried to delete the folders from the program files to get rid of it but the icon still appears in the tray and i can still right click on folders and the scan with mcafee option shows up. but when i do this it goes to the stupid white screen. grrrr at mcafee. im using avg now but mcafee is still there in the background, and to be honest it annoys the cr*p out of me. plz plz plz somebody help me. oh and by the way i put the folders back into the program files coz i thought it might update itself and magically be ok. and i use vista and i no longer have the cd for it. i know im in **** but if some could get me out of it, it would be great. thanx everyone.
