Thanks Hamrah, the thing that bothered me was that I had only opened the attachments I had sent myself from a computer which I knew to be clean at the time of sending (and still is). Everything which I was unsure about was being deleted unopened. The virus ate Sophos (not updated), Quarterdeck Cleansweep (also in need of updating) and McAfee (Virus scan and Firewall) which was updated when I last used the computer before heading off for Oz at the beginning of April. I had intended to update the McAfee when I had finished dealing with the email but the virus got there first.
Next time I go away I will update the virus protection before looking at my email when I return. I am just glad that I realised what was going on and was able to remember that Symantec usually have free downloads for these things and was able to access it.
