I have in the past had the stupid desktop icon reappering. In other post i changed the registry and used the desktop icon tool as directed. But after a recent update from mcafee the icon reppears and all the old tricks do not work. I dont know why mcafee can't write software after all these years plus they have not fixed this problem in windows 7, my vista is ok. This has been a problem for two years now. If anyone know how to remove this new problem please let me know, thanks.
This is a known issue that came with the latest update to the Security Center. The techs are aware of it and it will be addressed. The old fixes won't work.
