I installed this program as instructed. I have Earthlink's McAfee protection center. I tried to close it before the computer restarted after installation of Avast, but it restarts anyway. So now, when I turn on my computer, it freezes. It has been frozen for 20 minutes. There is a busy icon when I put the pointer near the tool bar and the arrow is normal on the desktop. I can't click on anything. I was finally able to pull Windows task maanger before it the computer logged in completely but it still freezes and I can't end the processes. I can't do anything on my laptop, whch is the computer I am having this problem on. What can I do?
