Skarpi, just be sure to keep your anti-virus software up to date.

It will protect your computer from viruses and worms and such things. You might want to scan the whole computer every week or two. That way the bad guys will be stopped.

If you don't know the person email comes from, don't open any attachments. Of course, you can still get a virus from someone you do know. That's why you have to keep the antivirus up to date.

Unless the antivirus scan of your computer showed a problem I'd just ignore this message.
