I had download your last build (2009/1/23) eScan V10.0.938.332..
I found a big UI problem if you installed eScan with Chinese language..
All the Chinese words in eScan UI become "?" to replace.
For example, Chinese words "病毒資料" will shown as " ???? ".
I checked the language files for this build.
These files had replaced Chinese words with "????....".
Your eariler build is OK.
May be you have some trouble for building these files.
Please use the eariler correct Chinese language to re-build the installation file for eScan AV and ISS.
Some customers waiting your correct build.
Thank you very much...
