I do have backups so no real problem there - apart from the hassle.

The only thing that was happening at the time was that I was deleting
files that needed getting rid of - old doc, xls files etc. I first
thought that all the files were zips but on closer look it seems they
were various types and not all in same directory. I have since done
full virus scan with none showing up and run adaware and spybot and
they also show everything OK.
Nothing has happened since last night so I am keeping fingers crossed.
What else can I do?

Thanks for you input.
