minacross,
I understand your point however, please consider what has to be done with a sample. Every variant cannot be entered into the database for every "new" trojan, worm or virus. It would become enormous. The proper method is to analyze the code string within each variant, comparing it to known viri to determine the "constant footprint" which is what is entered into the database.
This way whenever the "footprint" is detected, the virus is identified no matter if it is disguised in a "new shape". This is sort of how heuristics works as well.
The Avast Team is very busy in its' daily operation having about 2 dozen employees. I am sure that they look at every sample sent to them, test the sample, analyze it, and then when the best method of detection is determined.....add it to the VPS file.
I am sure that you can imagine how many samples get sent to them. WE on the forum are now 9000 strong with tens of thousands of Avast downloads. It is understandable that they cannot respond to each and every support request.
The end result is all that counts, and I truly believe that we are well protected with Avast Home and Pro.
