I just got two of these emails via Thunderbird.
It says that I've received a 21 page fax via Jconnect and that I need to download their software in order to open the file.
A). I don't know anyone who needs to fax me 21 pages. If I did, I would wave certainly told them to email me PDFs.
B.) If they discussed this with me first, clearly, I would have told them I run Linux and downloading third party Windows software was out of the question.
It's just another con to try and deposit a virus on a person's PC.
Just glad I don't run Windows.
