Here is a little something from one of Microsofts own FAQs! Will the virus impact my Macintosh if I am using a non-Microsoft e-mail program,such as Eudora? If you are using an Macintosh e-mail program that is not from Microsoft, we recommend checking with that particular company. But most likely other e-mail programs like Eudora are not designed to enable virus replication. Implying that Outlook is designed to replicate viruses!! This comment was quickly removed.. (Im surprised i was able to find it!!) MICROSOFT REALLY DOES BLOW!!
