For servers that are protected by Security Center, the antivirus feature provides deep scanning service against persistent viruses such as ransomware and mining programs. Security Center supports the immediate and periodic virus scanning methods. This topic describes how to scan for viruses by using the two methods.

Prerequisites

You have purchased the Basic Anti-Virus, Advanced, or Enterprise edition of Security Center. For more information, see Purchase Security Center.

Background information

The antivirus feature scans for the following types of viruses:
  • Ransomware
  • Mining programs
  • DDoS Trojans
  • Trojans
  • Backdoor programs
  • Malicious programs
  • High-risk programs
  • Computer worms
  • Suspicious programs
  • Automatic mutating Trojans
Immediate and periodic virus scanning can be performed in the following scenarios:
  • Immediate virus scanning: All servers in specific asset groups can be scanned. You can select all servers from one or more asset groups to scan for viruses immediately.
  • Periodic virus scanning: Some or all servers in specific asset groups can be scanned.

Immediate virus scanning

To immediately scan for viruses on your server, perform the following steps:

  1. Log on to the Security Center console.
  2. In the left-side navigation pane, choose Defense > Anti-Virus.
  3. On the Anti-Virus page, click Scan Again.
    If this is the first time that you are scanning for viruses, click Scan.Scan
  4. In the Select the assets to scan dialog box, select one or more asset groups.Select assets to be scanned
    Select an asset group in the dialog box. All servers in the group are scanned by default. You cannot select a server from the group. You can select multiple asset groups at a time.
    Note You can select only asset groups to scan for viruses. For more information about how to add groups, see Add a group.
  5. Click Scan.
    It takes two to five minutes to complete a scanning task. After the scanning task is complete, we recommend that you check the results and handle the related alerts in a timely manner. For more information, see Handle virus alerts.

Periodic virus scanning

To periodically scan for viruses on your server, perform the following steps:

  1. Log on to the Security Center console.
  2. In the left-side navigation pane, choose Defense > Anti-Virus.
  3. In the right-corner of the Anti-Virus page, click Settings.
  4. In the Defense Configuration pane, configure the scan cycle and assets you want to scan.
    Configure the scan cycle and assets you want to scan:
    • Cycle: You can set the scan cycle to 3 Days, One week, Two weeks, or Stop.
    • Execution Time: You can set the time range to 00:00-24:00, 00:00-6:00, 06:00-12:00, 12:00-18:00, or 18:00-24:00.
    • Scan Assets: You can select an asset, an asset group, or multiple assets from asset groups. Perform the following operations to select the assets that need to be scanned periodically:
      • In the Asset Group section, select a group and all assets in this group are selected. You can remove one or more automatically selected assets from the Assets section.
      • In the Assets section, enter an asset name and click the icon to search for the specified asset that needs to be scanned. Fuzzy match is supported.
    Note Based on the scan cycle, Security Center scans for viruses at any time point within the time range that you set. If you set the time range to 00:00-24:00, Security Center may scan for viruses at any time of a day.
  5. Click OK.
    Notice If you configured the scan cycle for many times, only the last configuration takes effect. Security Center automatically scans for viruses based on the scan cycle and assets you configured.
