Today, I tried to install a patch for a game on my Windows 8.1 computer.
However, when I try to download, the connection is immediately interrupted. When I try to download the file on another computer, and copy it using an USB drive, the file gets deleted as soon as I try to execute it.
It sounds like some antivir running havoc, but the computer has no antivirus software other than Windows Defender installed.
How could I find the cause of that issue?
