On-demand Help Needed

I have read the thread titled Bd A/v 2008 On-demand, and I see that the advice given is, "if you need an on-demand scanner then I suggest also to use the free version" and "if all you want is an on-demand scanner, better use free edition, v. 10".

That is what I want to do.... I would like to continue using BitDefender as an on-demand only AV scanner, which I have had great success doing with BitDefender 8 Free Edition.

Unfortunately, my attempts to do this with BitDefender 10 Free Edition did not go well (using bitdefender_free_v10.exe).

It seems that enough services and shields were being installed for a full time resident protection AV. I don't recall this being the case with BitDefender 8 Free Edition.

What I would like to know is, what services can I/should I disable in BitDefender 10 Free Edition to make this program an on-demand scanner only?

For example, vsserv.exe, some sort of library process (?), keeps wanting to act as a server, according to ZoneAlarm. It is not needed for on-demand scanning, is it?

And BDAgent.exe, which wants to start up, is not needed, is it?

But I believe that I do have to keep BDMCon.exe running in order for the program to work, correct?

Again, with BitDefender 10 Free Edition, there seems to be a lot of stuff trying to start up that shouldn't have anything to do with an on-demand scanner.

I have gone back to BitDefender 8 Free Edition until someone advises me what I am doing wrong, or what it is I need to do to get BitDefender 10 Free Edition to run as on-demand scanner only, without so many real time services and shields starting up and running.

Thank you.
