How to Unblock Blocked Files Downloaded From the Internet
By Timothy Tibbetts |
When downloading files from the Internet, Windows will look at the file and categorize it as High Risk, Moderate Risk, or Low Risk and decide if it's safe for you to run the file. Windows will then allow or block the file. If you know a file is safe, but blocked from running by Windows Security, here are some options to unblock a blocked file.
Before we get started, there are four places that a file could come from:
Internet
Local intranet
Trusted sites
Restricted sites
After that, there are three categories Windows uses to determine if a file is safe:
High Risk – If the attachment is in the list of high-risk file types and is from the restricted zone, Windows blocks the user from accessing the file. If the file is from the Internet zone, Windows prompts the user - "Windows found that this file is potentially harmful. To help protect your computer, Windows has blocked access to this file."
Moderate Risk – If the attachment is in the list of moderate risk file types and is from the restricted or Internet zone, Windows prompts the user - "The publisher could not be verified. Are you sure you want to run this software?"
Low Risk – If the attachment is in the list of low-risk file types, Windows will not prompt the user before accessing the file, regardless of the file's zone information.
