About Scan Now
You can initiate an antivirus scan in matters of urgency using the Scan Now feature.
In Ivanti AntiVirus most virus scans are performed on a scheduled basis as a result of policy settings. But in some circumstances an administrator may wish to run an immediate scan to prevent possible problems.
For example, when an administrator is notified of odd behavior among a group of endpoints, the suspect may be a recently announced virus variant (although no event alerts have so far been generated). Immediately running an antivirus scan on these endpoints will show whether they are infected. If it turns out that they are, the infected files can be cleaned or deleted. This kind of timely intervention can prevent malware spreading and damaging the network.
The Scan Now feature, (using the Virus and Malware Scan Wizard) enables you to run an antivirus scan and set its options. The scan can be carried out immediately, or scheduled for a time that minimizes impact on network performance.
There is a separate Scan Now feature that performs a Discover Applicable Updates (DAU) scan. This type of scan assists with the management and deployment of content items, and is not related to Ivanti AntiVirus.
