Well, I hate go back to this disgusting theme, but two viruses samples were sent to avast April, 23. I have sent them again. They are recognized as viruses from many other programs, avast doesn't. No answer, no inclusion in virus definition files, nothing happens. I asked from help to inform my client what danger this virus could propitiate, nothing. So, I am again, forced to appeal to this forum, the only place where it makes a difference.
