Are file uploads checked for spam / phishing?

Hi,

We have a form where users upload a file. If a user tries to upload a file with phishing or ransomware, does it get rejected?

I have checked our widgets and apps and did not find anything that will help you to do that, currently our File Upload field does not allow to upload .exe files which can be an auto-executable file and it can install a virus in your PC. 

I would suggest you to scan each file that is uploaded on your form, scan all the files you download and make sure you have your anti-virus up to date so you will avoid to get a virus installed.
