Dear user of imc.org,

We have received reports that your e-mail account was used to send a large amount of unsolicited commercial e-mail during the recent week.
Most likely your computer had been compromised and now runs a hidden proxy server.

Please follow the instruction in order to keep your computer safe.

Have a nice day,
The imc.org support team.
