Nurech.A is a worm that is currently being spread through a mass-mailer. This is not a new virus but it does look like this is a new outbreak of it.
The virus is sent out through a mass-mailer to as many email addresses as possible, with subject titles designed to encourage recipients to open them, (in spite of the fact that they know they shouldn’t).
So the current outbreak has titles like “Together You and I”, “Everyone Needs Someone”, or “CyberLove”, and has a female name in the sender field. Of course with Valentines Day on the way this email is more likely to be opened.
It’s interesting to note how often viruses are being circulated at the moment using events such as this, (or current news items), to try to entice readers to open them.
