Under attack

My inbox is overflowing with warning messages from my anti-virus service. I am receiving almost 100 messages per hour warning me that someone is attempting to send me a potential virus. The information in the message is:

The virus or unauthorised code identified in the email is >>> Possible MalWare ‘Exploit/Phishing-westernunion-6576’ found in ‘13812907_1X_PM1_EM7_MH_FW__message.htm’. Heuristics score: 200

This is so annoying!
