The most prevalent at the moment and causing all the recent troubles are the W32.Badtrans.B@mm and the W32.Aliz virus . The Badtrans and the Aliz are wreaking havoc because of the way they work. If you even preview the messages containing the virii , you are already infected , and therefore , unable to stop them grabbing incoming e-mail addresses and subject lines , hence they will appear relevant to your interests!! However , they do give themselves away by adding another " Re:" at the beginning and the sender will have an _ before their e-mail address .Do please visit one of the information sites , and read the descriptions of how they work . This current outbreak would have been easily preventable , if people kept their Virus checkers upto date and those who don't have a virus checking program installed would do well to get themselves one POST HASTE.... It is a waste of time trying to reply back to the sender because they may well have problems of their own trying to remove the virus!!! P.S. I am very sorry for those who have been infected , but if you value your research , you should protect your investment of time , energy and money!!
