I could not simulate the troubles again (I won’t remove msdos.sys and config.sys from the exclusion list again) but I have to report some instabilities in Windows XP. Like other users (http://www.avast.com/forum/index.php?board=2;action=display;threadid=1593 and http://www.avast.com/forum/index.php?board=2;action=display;threadid=1467) my system is unstable now, specially resuming from ‘standby’ and ‘hybernation’… CPU useage goes to 100% and the system freezes… Only hardware reset (boot) works… not even CRTL+ALT+DEL…
I’m not sure what is causing this, so, by now, I cannot say anything to avast! team related to the new version 4.1.289… I’ll keep reporting :-\
