You probably have one of these dreadful Klez viruses that replicates itself through ones address book. Go to www.symantec.com and click on virus removal tools / downloads and it takes a couple of seconds to find and download the fixw32klez tool (that names off the top of my head - but it's pretty straight forward). This wretched virus has been doing the rounds quite vigorously, so worth doing a double check even if you are running a virus-check programme. Regards, Hille Cook VILLAS
