You may agree a handful of downloaded files from unknown authors carry the risk of running some sort of viruses. These files feature an executable code and therefore are dangerous. What is worrisome, the threat rises up exponentially when more people have access to the same machine.
For instance, in a home environment, kids or other individuals who do not have much knowledge of malware may end up downloading a file that may contain malware. If you have anti-virus software installed, well and good. But if you don’t want people to download files from the Internet to your machine, as an additional precautionary measure you can disable the file download option of your Internet Explorer.

From now onwards no individual will have the freedom to download stuff through the browser! Internet Explorer will display a warning message stating that the current security settings do not allow the downloading of files every time they attempt to download something.
When a person tries to download something, he will see the following message:
Security Alert: Your current security settings do not allow this file to be downloaded.
