Upon successful comparison, the items will be categorized by color. Red as bad or suspect, yellow for suspect or benign items and green for benign. Non-colored items means the item is unknown in Emsi Software’s database. If this is the case, you can push another button send it for analysis so the next time you refresh and when their malware research team has finished analyzing the submitted item, you will get the result (whether it’s bad or not).
