Today I've downloaded publicly available source of Kaspersky 2008 suite. Just to check what is inside. I really sympathize researchers who used it. But the most interesting thing is attached file:

Thus hackers had the source since 2008! Perhaps this is cause that new versions of undetectable viruses appear from time to time.
