Avast reisident Scanner disabled

Hello I have been using Avast Home Anti virus for about 2 mo now… All of a sudden I am having problems with the resident scanner being disabled via an error ( i cannot replicate the error message to repeat here) to fix this I have to right mouse click on my computer and chose manage,and go to services and applications,click on services,and make sure all avast properties are set to automatic. reboot computer . I have done this procedure and it will not allow me to enable the scanner… This has happened at least once and tonight it will not after several reboots. I do not know how to fix this and am running A Laptop with win xp intel 4 2.7 ghz and 40 gig hd with 190 mgs ram

Please advise, Thanks (K)

Try making a repair Add/remove programs–> Avast–> repair… You need to be online to do this

To proper help we need to know which error it is or, at least, which resident provider is wrong…

Look, Mail Scanner is ‘manual’ started not automatic…

Better will be, as adviced, try to repair your installation.
