Hi Deb,
At times, you may download a file from the Internet or receive one by email. Windows classifies certain files as unsafe downloads and attachments by identifying the files type and the security settings for each file. To unblock your file, follow the steps given below:
- Right-click on your file.
- Select Properties.
- Make sure that you are on General tab.
- In the Security option, you may see the message This file came from another computer and might be blocked to help protect this computer. Click on Unblock button.
Let us know if you have other concerns.
