IM Shield didn't Scan Yahoo Messenger

Hi. I just did clean install of my avast to version 7 this morning and it install perfectly, every module running. And this morning, i update my YM too by downloading YM client from www.filehippo.com. So what happen is when i check on my IM shield to look how it perform, the shield show 0. Nothing is being scan from the first start of YM. So this worry me, whether the module problem or YM client problem. As far i know, filehippo is well know website and it clean.
So here my spec, Windows 7 ultimate 64bit, YM installed on default directory Program Files(86).
Hope thing sort up soon.
Here some Snapshot.
