Okay, since posting this, I have done a system restore and am now able to use Mozilla. I did an OTL log, and I have attached it to this post. I'm not sure if the problem is still there after the system restore.
Any help you can provide or suggestions are most appreciated! Thanks.
(The laptop that has the "Win 7 Security 2011" problem is an ACER one series Model NAV50)
Thanks in advance for your help!
