Dear Andrew, What I have received is a bit different. I had also the text/plain and html parts but I have another one too. This was an attachment called READER_DIGEST_LETTER.txt.pif . If decoded and opened it starts spreading in the WINDOWS directory. Now I have the report of the AntiVirus, it is W95.MTX which has also a warm component infected with the same virus that spreads through e-mail. It also patches WSOCK32.DLL. I am still running after it instead of seeing of my work. I am terribly upset upon this incident because threatens my recent data deposited on this computer.
