To limit the propagation of viruses through email, it is no longer possible to send email to and from VUB/ULB email addresses containing Windows executable attachments.

The newest generation of email viruses have become much more aggressive, more difficult to clean up, and requires a great amount of time investment from VUB/ULB staff members and students to clean up infected computers.

Therefore, as of 15 February 2005, it is no longer be possible to send email messages to and from VUB/ULB email addresses with Windows executable programs in attachment, such as.COM,.BAT,.PIF,.HTA,.EXE,.CPL and others (see below for the complete listing). These files are the most common format used to propagate computer viruses by email and are in most cases of no use to most users.

Attachment types used by popular Windows applications such as.DOC (Word),.XLS (Excel),.PPT (Powerpoint) as well as the popular.ZIP will continue to be accepted.

We do remind users that there are a number of viruses using the.ZIP format - protected with a password or not - to propagate, but we count on the receiver not to open suspiciously looking emails and their attachments.

The same measures are already frequently used by other renowned academic institutions and companies, who like the VUB/ULB wish to react pro-actively on email virus issues.

Peter Van Rossem -

We prefer mail message blocking as opposed to the elimination or replacement of potentially dangerous attachments because, if it concerns a legitimate message, the sender can immediately rename the attachment type and resend.
We also avoid the delivery of nonsensical mail messages in the case of a real email virus.
