Modify Virus Scan time for Critical Report

[CorpseQ]

Hi, i want to modify the virus scan critical status, what i mean by thats is that i want to be able to change how many days would take to promp the Critical status because right now i have servers that takes several days to perform a full scan and im getting the Critical Status before the task is able to finish. Can someone help me with this? I really need to change this so the reports are clean.
