  4. The ESET Online Scanner will start download virus definitions from their server. This process of downloading may take some time if you do not have a fast connection. On my 2Mbps Internet connection, it took around two minutes. If you have a slower connection, you can go and enjoy a fresh cup of coffee while the downloading finishes.
