Check your anti-virus documentation. The anti-virus documentation SHOULD tell you how to set up an 'exception' folder that you can download to without checking for viruses. If you don't want to set up an exception folder, temporarily disable your anti-virus, and then download.
You didn't say what anti-virus you are using , but the anti-virus software is probably what's preventing the download, since you tried to download using other browsers. Some antivirus programs will not permit downloading a compressed file that contains an executable file.
The compressed file has been on site for some time, and nobody else has reported your particular problem. As I said before, I can download the file;, there's nothing wrong with it.
