Windows executables. Cela peut generer une fausse alerte si vous envoyez des 
executables par e-mail. Lisez le rapport ci-dessous.

  Our viruschecker found a VIRUS or a Windows executable file in your email to 
"".
           We stopped delivery of this email!

The e-mail filter blocks e-mails that were recognized as infected
  by the anti-virus software, and as an extra sanity measure, it also 
  blocks Windows executable files. This later behavior can introduce 
  fake alerts if you try to transfer Windows executable files using 
  electronic mail. See below.

    Now it is on you to check your system for viruses.
