Q

How can I run third-party antivirus software?

If you ever have trouble downloading and running antivirus software, this expert advice will teach you to use Internet Explorer security settings to allow the download.

I am getting a "Windows security warning" box when I try to download McAfee's antivirus software. When I click the download button, a box pops up and says "Windows security settings do not allow download." How can I make third-party antivirus software work with a Windows machine?
I'm assuming you are using Internet Explorer (IE) for the download. If so, it's trying to tell you that you're downloading an executable or similar file that's potentially dangerous. Try setting your IE security to a lower setting via the following:
  1. In the IE's Tools menu, click Internet Options.
  2. In the Internet Options dialog box, click the Security tab.
  3. In the "Select a zone to view or change security settings" control, make sure the Internet icon is selected.
  4. In the "Security level for this zone" control, set security to Medium-high or Medium.
  5. Click OK.
  6. Try the download again.

This should do the trick. If not, you can always try to download the software using another browser such as Fi

refox.
