Simple answer "NO".
In almost all cases, these so called virus warnings are hoaxes, intended to get you scared, and to fill the internet email system with noise, resulting in a slowing of the net, as resources are used up.
Think of it this way, if you have a good upto date Anti-Virus program, you should have as good protection as you can get, and therefore little to worry about. If there are people out there without protection, that is, not running an Anti-Virus program, then your warning would likely serve them no purpose.
Always remember good practice with any computer connected to the internet, or otherwise. Make regular backups of anything important to you, and other users of your machine. And don't forget to test the backups to ensure they are valid!
