There were two replies suggesting to use Check[] to abort evaluation 
when a message is generated.

Note that while Check does return a different result if a message was 
generated, it does not actually interrupt evaluation (it completed the 
evaluation of 'expr').

See here for an example:

http://mathematica.stackexchange.com/questions/5534/check-does-not-interrupt-evaluation-of-the-expression-when-a-message-is-emitted

Please see here for a method that will reliably abort immediately when a 
message is generated.
