I just answered the question as it was asked, which as stated seemed to have nothing to do with either IE 11 or Outlook mail. Don't know what other kind of answer you were hoping to get. "Shutting down" the computer certainly means that no virus/malware can get in or out...so your computer is safe. That's what you asked.

mikie: can't say I understand the ghack... site well. It says to determine if my IE settings are already safely set in 'advanced' security mode by going thru Tools, Options, Advanced, and then down somewhere in the Security area to look or do something that is not clearly defined. I see that there is a check box for Allowing some 64 bit security setting that is checked in the ghack picture. It is not further described and it is not the highlighted item in that list. In my IE 11, that box is not checked, but by going more directly thru Tools, Security, I can see that 'advanced security' is selected. I suppose that 64 bit box might need to be checked, but it appears to be allowing more rather than less access and that seems like a weakness rather than an improvement. So, I don't know what I am supposed to do here. And it seems odd that a supposed huge hole that requires massive Microsoft scrambling can be fixed by checking a box or not!!! The ghack site then goes on about something called Enhanced Mitigated Experience Toolkit. It doesn't tell how to get it safely and also implies it is not needed if my security is set appropriately. Gee Thanks. Finally, it comments on Flash. I have already upgraded but I would like to point out that the Adobe terminology and others as well tend to suggest that it is an update rather than a newly named version. It seems odd that what seems like a patch, is a new version; but whatever, I guess.

I sometimes get that message when I have a loose connection, either with my cable modem or the Linksys router. It will clear after checking the connections and/or pushing the reset button. Just my 2 c's. Bejay

The attraction of IE alternatives, especially 5 years ago and more, stemmed more from how clunky IE was rather than the superiority of the others. Firefox/Netscape/Opera were ok and worked fine, IE was awful. The decision for what best to use was easy, though much of Corporate America stuck to IE for employees' internal use. Today, I think IE has done a lot of catching up. I find it pretty decent and comparable to the others though I don't use it as my default browser. OP, there are a half dozen or more solid browsers to choose from, all have there own peculiarities, problems and features and all are free. There's no need to persist with something that isn't working for you.
