Thanks for that link. I thought I'd go ahead and report back on the results of me test.
On that site, you could either download the file from http or https. Avast would not even allow me to download the file (wouldn't start the download) to ANY location (local or network) if I just tried to download from the regular http links.
Downloads were allowed with the https links. Windows Defender actually picked up on it, NOT avast when I downloaded either to a local directory OR to a network location. However, when I manually scanned the file with Avast after I downloaded it locally, Avast did detect it. So that's weird? I wonder why it did not pick up on it when downloading from https?
Anyway, I don't think I have a definitive answer, but I believe I will just make an effort to download locally first and then move to the network location. Better to be safe than sorry. Don't really want to take any chances with infecting the other PC.
Thanks for your help!
