I was hit by the worm KLEZ.H last week. Fortunately I noticed the infection VERY quickly. It spreads through the email address book and I know it went out to several people on ribnet as Andy telephoned me. It shows up as a 'non deliverable mail' message and is in the attachment. DO NOT OPEN THIS. DELETE IMMEDIATELY.
I am uninfected now. In fact I've just this minute scanned my system again.
How can we recognise NIMDA - D John?
