Hi  Pranav54,
This situation as you descripted normally because Security settings on your computer blocked this file. As a result, the file you attempted to download was removed by the Windows Attachment Manager.
1.Open the Internet Explorer.
2.In the Internet Properties window, click the Security tab, click the Ineternet zone (globe icon), and then click the Custom level button.
3.In the Security Settings window, scroll down to Downloads > File download.
4.Click to select Enable.
5.Scroll down the list further to Miscellaneous > Launching applications and unsafe files.
6.Click to select Prompt.
7.Click OK.
Besides, try the following workaround to disable the virus scanning temporarily, and then enable the virus scanning immediately after you complete downloading the program or file. You can also find the details below for instruction:
