I’m a frenchman so my english is not very good but i hope you can understand
thank you

Presumably you are talking about the web shield detection, see image, is this what you mean ?
If you choose Abort Connection, the file is usually discarded and blocked from being saved (there are some weird exceptions) but why in the world would you want to open a file flagged as a worm, etc.
If it did get on your system then you would likely get another alert by the standard shield and the safest option is ‘Send to Chest’ (Quarantine).
yes, it is.
thanks for your answer 
No problem, glad I could help.
Happy New Year.
