Well... if you can't view mcafee than you have the conflicter worm... which might be causing you some issues.
This is only happening to a few people... anyone who is having this issue, I think the only way for me to help is to get on your computer and see it for myself.
There is the very secure, very easy to use application "GoToAssist Express" it developed by the same guys who from Citrix Solutions. What we do is, you goto a website, pop in a 9 digit key privy only to you, and we share your computer session.
User has complete trump controls... meaning, YES i can control the mouse and keyboard, but at any moment if you (the user) touches either, it will disable my abilities to do so until you become idle again.
If you agree to this, just send me a PM here on the forums and we'll get it rolling. I SWEAR I won't hurt anything. The only way I'm going to figure this out is by first-hand.
