Professional Edition: fixed installation of the ScriptBlocker module which could have previously caused various problems (e.g. in Internet Explorer)
program installation now completes successfully even if Spyware Doctor is installed (the "OnGuard" module of Spyware Doctor contains a bug that was previously preventing the avast installation from working correctly)
program installation now better handles the situation when repairing previous (corrupted) installs
mail scanner: fix for marking of new emails as "read" (the problem was taking place in Thunderbird 2.0 in conjunction with some IMAP servers)
fix for scanning of areas with East Asian names (Windows NT/2000/XP/Vista)
