After updated to the latest version of avast! (4.7.986 Home Edition), I found that avast! does not scan files if selected folders have Chinese characters in its names. The avast! Simple user interface and Explorer extention (ashQuick) have the same problem.
For example, If I select “E:\Virus”, avast! will detect virus in “E:\Virus\病毒”. But if I choose “E:\Virus\病毒” directly, avast! scans 0 file.
Does the same problem apply to the on-access scanner, too?
Ie. what if you e.g. place the eicar test file to that folder? Does the Standard Shield detect it?
I have tried to change the setting of language for non-unicode programs. The problem disappeared if I select English. It is not bad for me for I does not use Chinese software very often. However, most users in China cannot change that.
The problem appeared again when I restored the setting to Chinese(PRC). Hope avast! can fix this problem or find a better solution.
