I'm using outlook xp that came with office xp, I have AVG antivirus which has a Oulook express plugin to stop nasies like that,
I checked out Symantic and this is what I found out...
This is exactly what I was sent in the first place but it seems to have got around and now I'm getting e-mails from lots of different people but with different subjects and message bodies..
W32.Yaha.F@mm is a mass-mailing worm that sends itself to all email addresses that exist in the Microsoft Windows Address Book, the MSN Messenger List, the Yahoo Pager list, the ICQ list, and files that have extensions that contain the letters ht. The worm randomly chooses the subject and body of the email message. The attachment will have a .bat, .pif or .scr file extension. Depending upon the name of the Recycled folder, the worm either copies itself to that folder or to the %Windows% folder.
The name of the file that the worm creates consists of four randomly generated characters between c and y.
It also attempts to terminate antivirus and firewall processes.

The worm uses its own SMTP Engine. It attempts to use the infected computer's default SMTP server to send mail. If it cannot find that information, then it uses one of many SMTP server addresses that are hardcoded into the worm.
NOTE: None of the above mass-mailing characteristics could be reproduced in the lab environment.
That is the most important stuff, make sure your up to date and backed up,
