What options is it you are looking for ?
Left click the avast 'a' icon and that will open an On-Access Scanner window or right click the avast 'a' icon and select On-Access Protection Control. If there is a Details... >> click that button and you will see all the different Providers (Shields) and their settings. Don't go tweaking without first reading the avast help file, Resident Protection, so you know what it is you are doing.
The Default avast settings provide a good balance between protection and performance until you get more used to the program.
Providers that are greyed out aren't running, however both of the provider you mentioned P2P and Network Shield are enabled by default, this is what I meant by not tweaking. If you haven't terminated these options then there is something wrong with your installation. You should have the Network Shield enabled, if you don't know what P2P (peer to peer, file sharing) then it is doubtful if you have any of the applications that it monitors.
What avast processes are running in Task Manager, they begin with ash or asw, see image ?
Have (or did) you another AV installed in this system, if so what was it and how did you get rid of it ?
