Thanks.
So, avast! doesn't have its own setting for temp directory. It is bad.
Is it possible to follow your advice in win98SE? (I couldn't find where environment variables are set in this OS). Will I have to edit registry?
Anyway, this will redirect all data which before should be placed in the "windows\temp" folder. Am I right? I think you'd better make this setting own for avast!
