I wouldn't bother fixing Internet Explorer 7. I would up date to version 9. It's the most current version for the operating system Vista. Here is a link that might be useful: explorer/ie-9

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.

The setting is in IE version 10 & 11. Mine is version 10. By its default setting, the Enable Protected Mode should have already set. To check, open IE. Under "Tools" (top menu), select "Internet options". Under the "Security" tab, you will see "Enable Protected Mode". This should be checked. You can also disable the Flash Plugins. This bug won't work with Flash plugins disabled. To disable, open IE and go to "Tools" and select "Manage add-ons". Under "Toolbars and Extensions", you will see to the right "Adobe Systems Incorporated". Under this, "Shockwave Flash Object" is listed. When you select this, you will see a "disable" at the bottom. Click on it to disable; then, select "Close" to get out of the setting. Doing both, you can continue to use IE.

I finally figured it out. If others have this problem, got to Control Panel > Programs and Features > For Win7 in left hand panel click "view installed updates > scroll down to Microsoft Windows, then find whatever it is you want to install. If the install was very recent, it is easier to change the view by clicking on Installed On tab, then all will be arranged by the date it was installed, bringing the recently installed to the top. Then just hit uninstall.
