Normally, when I open my email program, it logs on to my email server and either download my mail, or tells me there is no mail.  As of today, when I open the email program it locks on "logging on to mail server" and does nothing else, or if it does log in, then sits there saying you have 3 messages and never downloads them.  This has only happened as of today, and only on my Windows 8 machine.  I can get email on my laptop, which has Win 7, but even then, the email system is slow.  This was NOT the case last evening, when I was last accessing emails.  Something in today's update mucked up my Win 8 machine.  If I disable Bitdefender, altogether, my mail system works normally.
