Firstly I'm confident that this email did NOT come from mybebook.com.
It's a typical spam/phishing/trojan/virus email. The link to download the bill will download a file called 'bill.exe', which undoubtedly contains a trojan/virus of some sort.

I'm guessing that they may have found my email from this forum, so I'm posting this to alert less tech savvy ereader users to be on the lookout.
