Just as a warning, I have had 2 emails sent to me today containing the '
I-Worm/Netsky.Q' virus. 
This is the first time I have ever had an email sent to me with a virus in it (thanks to AVG for spotting both).
As normal, ensure you are very careful with any emails sent to you with attachments, and get up to date anti-virus software (even if it is free).
