I don't understand the comment from Djalmir. What can I do with it. It looks that I cannot start aswmon2 en aavmker4 from the command prompt, so the rest of his comment is not useful for me.
Can someone please help me to get Avast running? I've installed it on other PC's and partitions (XP and 98) and there it is running very well. But on the XP (Home Edition Dutch) partition I work with I cannot get it running.
