It is nonsense. Most, if not all Anti-Virus software will advise you that the file you are attempting to download may be harmful. Do you want to do it anyways.

After the file has been downloaded and you open it, you will get another warning. This file...blah blah blah....usually get the option to open in some type of sandbox environment or cancel the pending action(s) Files get tagged by various AV software all the time. Also, I notice from your post that you got a big honking notification about that file.

There is no way you can download a 245MB file and have it just disappear into the ether.
