Thank you for using Microsoft products.
With friendly greetings,
how used we are to seeing real security warnings about Microsoft Internet Explorer and Microsoft Outlook, it was only a matter of time before someone disguised a virus as one.
The message quoted above is not a real Microsoft security warning. The q216309.exe file attached to it is a worm which will, when executed, send mail to addresses found in Microsoft Outlook's address book (and addresses found in any locally stored .htm, .html, .asp, and .asp files) as well as installing a trojan horse which allows remote access to the infected system. (McAfee reports that "the worm was buggy, and did not successfully use Outlook to spread," however.)
