Sorry. I forgot one thing. If you have your email program set to 'preview' your email before you open it - (you may have a box below the list of messages that shows you the first few sentences of an email message), be aware that you will get this kak.worm without opening a message yourself. Just having the preview window open is enough for it to "worm" its way into your files. So as a precaution, make sure this preview window is closed. Barb K (the other Barb) Subject: Re: A worm? Mine, too! So I "quickly" shut down and re-booted.
