    My "Security Center" tells me that "Security Essentials" is not turned on, however "Security Essentials" indicates it is on and I am protected. Which am I supposed to believe? I have all cuyrrent updates installed to the best of my knowledge. What should I do?

    The reason that no one can here get their "Security Essentials Virus protection" to operate correctly is that: MICROSOFT DESIGNED IT!

    My security is turned off and there is no information anywhere to tell me how to turn it back on. WTF! I am more than just a little annoyed.

    My IE browser has been hijacked by IncrediMail and I cannot find a fix on your website and obviously all the security updates I have done have NOT fixed it!

    My virus protection is off and it won't come back on.  What is wrong?  If for some reason I do get it on, when I turn my computer off and then turn it back on it is off again.
