Hi I sent a copy of the virus to avast and up to now avast 5 still does not seem to detect it.
welcome to the forum. strange how long ago was it you sent it to avast and how did you sent it? if it is through the chest then the file should still be in there rescan it with avast again will it come up as a threat?
you could upload the file to virustotal.com and post result here so we can have a look on the file.
hope this will do as an answer for you.
