scanning at start

How can I configure the scanning at start to delete or, if not possible, quarantine items not deleted withowt I having to wait the long process to do manually do these same actions?

I don’t think it is ever a good idea to have an AV auto delete any detected threat before 1st verifying if the threat is valid/real. Quarantine is always the best option, IMO. You can always restore the file(s) from there if the threat is a False Positive. Under the ‘Security’ tab select the shield, click on ‘Settings’ and then click on ‘Actions’ to set your preference(s).
