CCA cannot detect AV

[Dennis Xu]

I have a strange case which I have never seen it before. The latest CCA 
version 4.1.6 cannot detect AV products on a chinise version Vista Home 
Basic laptop. We tried to install both McAfee 8.5 Enterprise and AVG 8.0 
Free Edition and CCA says 'No AV Detected' for both cases. We use the 
av_inst_ANY_vendor check. Anyone has seen the similar problem?

thanks.
