Some question

Avast Free Antivirus / Premium Security
1
  1. How many viruses is in à program Virus Base?
  2. Heuristic - where is enabled/disabled?
  3. How I can to adjust a “Internet Mail” in programm (server, ports and other…)?
  4. Where I can found a Russian testing languages module?

  1. Cannot be exactly defined because it uses generic detection which covers multiple viruses or entire virus family,but it covers around 36.000 unique viruses.

  2. Currently not available,but it has very good generic detection and very fast antivirus team response,so they can cover this little “hole”.
    You might expect this feature in some next version.
    Heuristic scan is already implimented for Internet Mail,Outlook/Exchange and The Bat! mail scanning modules.

  3. You can adjust more settings for mail protection by editing avast4.ini file located inside C:\Program Files\Alwil Software\Avast4\DATA\ folder (this is default installer path)

  4. There is currently no Russian language interface for avast!
    Are you interested in translation?

Igor sad that:“Actually, the translation of avast! user interface to Russian is almost complete. A test version should be available quite soon.”
But I offer to prepare Russian language module for your program by some pay.
