Its a Mytob Month

Apparently it is … there are already 10 cases of MYTOB worms
starting from April 8, the latest of which is WORM_MYTOB.PZ
(currently making the rounds). But there really is no need to
worry, the sample has already been sent to our very capable service
team and all solutions for the latest WORM_MYTOB are currently
being made and will be available soon.
