New variants of MyDoom

Yesterday there were found 3 new Mydoom variants: MyDoom.U, V and W. All these variants are very similar to each other. All of them download and activate a backdoor called 'Surila'.
There is also a hidden text inside all these Mydoom variant files: "We searching 4 work in AV industry."
Please note that the antivirus industry does not hire virus writers! Not only is it deeply unethical to write malicious code, but it raises issues as to whether you could ever be trusted to develop the software which protects millions of users around the world from attack every day!
