::slight_smile: Just entered the authorization key and AVAST is now working fine anf fully functional.

Regarding, if AVAST for DOS 7.70 can run in windows 2000, have you considered a free download of AVAST 4 Home wich is compatible with Windows 95/98/Me/NT4/2000/XP.

For download the english version follow this link: http://www.avast.com/eng/down_home.html
