Run third-party malware detection tools in Windows

Question: I am getting a "Windows security warning" box when I try to download third-party (non-Microsoft) antivirus tools. 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 malware detection tools work with a Windows machine?

Windows security threats expert Kevin Beaver offers this response:

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 Firefox.
