The link in the email varies, some other examples seen are:
http://nrjchat.org/ONLINE~IMPORTANT-UPDATE/last-update.html
http://utokatalin.ro/ONLINE-BANKING_IMPORTANT/update.html
http://cab.gov.ph/ONLINE-IMPORTANT~UPDATE/last~update.html

Visiting these sites goes through some javascript hoops, and then leads to a ZIP file download which contains a malicious EXE that changes every time it is downloaded. The files are named in the general format update12345.zip and update54321.exe.

The file itself is an Upatre downloader, with poor detection rates [1] [2] [3].

The Malwr report shows traffic to the following URLs:
http://202.153.35.133:33384/2001uk11/HOME/0/51-SP3/0/
http://202.153.35.133:33384/2001uk11/HOME/1/0/0/

http://202.153.35.133:33387/2001uk11/HOME/41/7/4/
http://essextwp.org/mandoc/ml1from1.tar

Out of these 202.153.35.133 (Excell Media Pvt Ltd, India) is one you should definitely block. This downloader drops several files including (in this case) %TEMP%\sJFcN24.exe which has a VirusTotal detection rate of just 3/57 and is identified as Dyreza.C by Norman anti-virus.
