An email which contains an attachment with a filename of dontopen.exe has been received by Sophos. When the user runs the executable file, it will display a message and it will shut off the computer of the user in 60 seconds according to Sophos.
The display says, “This system is shutting down. Please save all work in progress and log off. Any unsaved changes will be lost.” It also has another sentence but the article covered the last word.
The file was identified as Troj/Shutdown-I. A screenshot of the message was included in the article. The author notes that they the clock back so it does not say 60 seconds in the screenshot.

This may seem a bit harsh but, If you are over the age of 10 and you actually run a .exe file in your email named dontopen.exe. I think your computer should be taken away from you.
You should be force to take a remedial computer class before being allowed back on any system.
Possibly a public flogging may be in order here as well.
i agree, with everything but the flogging.
that should be mandatory and the first punishment to happen.
What if they’re on a ship? Can we keelhaul them?
I mean seriously, do people still open .exe files in their emails from people they don’t know? I thought we got past this in the days of windows 98. Plus I also find it hard to believe that the most crude free antivirus wouldn’t stop this dead in its tracks. I doubt you could even run it on Vista.
