During a virus "outbreak" scenario, it is recommended that you enable the Scan on Scanner Update feature in General Options, causing files to be scanned repeatedly each time your scan engines are updated.
You would not normally select this setting, but if your server has a lot of free capacity and the user experience is not impacted, having this on all the time ensures the best possible level of protection. Keep in mind that selecting this feature can have a considerable performance impact on a busy server, as it leads to significantly more scanning.
