being prompted to sign into computer when trying to move infected file

hi

i am being prompted to sign into computer when trying to move infected file into the chest…is this normal i am new to using avast?

SS below

thanks for any answers to this, i am afraid that if i sign in i will be effected by this virus

A screenshot would probably help

This depends on the file, in MacOS the prompt to sign in is to elevate you to admin rights for that action. So this could be a file that belongs to another user on the Mac or a file in a system location
