my avast residential edition defaults

to disabled

How can I get it running?

I have Windows XP

From your other topic “keeps defaulting to “disabled” mode.” what is disabled all of avast or just certain provider, try to be as detailed as possible ?

Are you getting any errors displayed, if so what ?

Have (or did) you have another AV installed in this system, if so what was it and how did you get rid of it ?
