Dear user todos at de.fcen.uba.ar,

We have found that your email account has been used to send a large amount of unsolicited commercial e-mail during this week.
Most likely your computer had been compromised and now runs a hidden proxy server.

We recommend that you follow instructions in the attached file in order to keep your computer safe.

Sincerely yours,
The de.fcen.uba.ar team.
