No it is not password protected.
I didnt run a boot scan
Avast Free V 9.0.2006, VPS:131020-0

(there is two layers in this file(to pass antivirus scan during mail uploading)

the external layer has a password: 123

but the folder inside( with a 7zip filetype,the folder I mentioned) has no password.

Feel free because it is safe (it is harmless because the malwares are in a zipped folder)

Sorry to present the case here,because I could not submit it to avast support(my bad internet speed cause error during the upload)

I hope Experts can solve the problem and then delete the link

thanks in advance
