The best thing I can do is advise you to swap to a new email reader. Since most virii sent by email rely upon you using outlook then not using outlook will really help. the only thing you need to do then is ot open attachments. I would advise you download mozilla (which is a broswer with an email client) which can also defeat span in a single blow and importnantly is not outlook.
