Release Time

Xcitium Client Security

Click 'Antivirus' > 'Scanner Settings'

The antivirus settings

Click 'Antivirus' > 'Scanner Settings'

  • The settings area lets you configure real-time scans, manual scans, scheduled scans and exclusions.
  • The settings you implement here will apply to all future scans of that type.
  • Items added to 'Exclusions' are omitted from all types of scan

Open scanner settings

  • Open xcitium Client Security
  • Click the 'Antivirus' tab
  • Click 'Scanner Settings'


The virus scanner settings interface has the following tabs:

Real Time Scan Settings

Click 'Antivirus' > 'Scanner Settings' > 'Real Time Scanning'

  • The real-time scanner is the 'always on' virus monitor which runs in the background, checking files when they are opened, copied or downloaded.
  • The real-time scanning area lets you enable or disable the scanner and configure scan options. We highly recommend you keep the real-time scanner active at all times.

Configure real time scanner settings

  • Click 'Antivirus' > 'Scanner Settings' 
  • Click the 'Real Time Scanning' tab, if it is not already open 

Real-Time Scanning 

  • Use the slider to activate or deactivate the real-time virus monitor:
    • On Access - Any file opened is scanned before it is allowed to run.
    • Disabled - Switches the real-time scanner off. 

Please note: Real-time scanning is not supported on Debian. This feature is not available on Debian. 

Detection Settings

  • Automatically update virus database - CCS checks for and downloads the latest database at system start-up and regular intervals thereafter (Default = Enabled). 
  • Automatically quarantine threats found during scanning – Select whether or not CCS should automatically take action against malware found by the scan (Default = Disabled). 
    • Enabled = CCS moves detected malware into an encrypted holding area known as 'quarantine'. Files in quarantine cannot run and pose no threat to your system.

      Click 'Antivirus' > 'Quarantined Items' to review quarantined files. You can restore items to their original location or permanently delete them. See this wiki to read more. 
    • ​​Disabled = CCS shows an alert when a malware is found, with its details. You can choose to clean the malware or to ignore the alert.
  • Show notification messages - Alerts appear at the bottom-right of the screen whenever malware is found and moved to quarantine. Available only if 'Automatically quarantine threats found during scanning' is enabled. (Default = Disabled).  
  • Heuristics Scanning Level - Heuristics is a technology that analyzes a file to see if it contains code typical of a virus. It is about detecting 'virus-like' attributes rather than looking for a signature which exactly matches a signature on the blacklist. This allows CCS to detect brand new viruses even that are not in the current virus database.

    The drop-down menu lets you select a sensitivity level. The sensitivity level determines how likely it is that heuristics will decide a file is malware:
    • Off - Disable heuristic scanning. This means that virus scans only use the 'traditional' virus database to determine whether or not a file is malicious.
    • Low - Least likely to decide that an unknown file is malware. Generates the fewest alerts. Despite the name, this setting combines a very high level of protection with a low rate of false positives. xcitium recommends this setting for most users. (Default)
    • Medium - Detects unknown threats with greater sensitivity than the 'Low' setting but with a corresponding rise in the possibility of false positives. 
    • High - Highest sensitivity to detecting unknown threats but this also raises the possibility of more false positives. 
  • Do not scan files larger than - Specify the largest file size that the antivirus should scan. CCS will not scan files bigger than the size specified here (Default = 20 MB). 
  • Keep an alert on the screen for - Specify the length of time that virus alerts should stay on the screen. (Default = 120 seconds).

Click 'OK' to apply your changes. 

Manual Scanning

Click 'Antivirus' > 'Scanner Settings' > 'Manual Scanning'

The options you set here apply to all on-demand scans on your computer. For example, these settings are used when:

  • You click 'Scan Now' on the home screen then run a full or quick scan 
  • You scan an item by dragging it into the scan-box on the home screen
  • You scan a file in the 'Run A Scan' from the 'Antivirus' menu

Configure manual scan settings

  • Open xcitium Client Security
  • Click 'Antivirus' > 'Scanner Settings' 
  • Click the  'Manual Scanning ' tab 

Scan archive files - The scan will include compressed file formats such as .ZIP and .RAR files. Supported formats include RAR, WinRAR, ZIP, WinZIP ARJ, WinARJ and CAB archives (Default = Enabled). 

Automatically update virus database before scanning - Check for and download the latest virus signature database prior to running a scan (Default = Enabled). 

Enable cloud scanning - Improves scan accuracy by augmenting the local scan with an online look-up of xcitium's latest virus database. Cloud Scanning means CCS can detect the latest malware even if your database is out-dated. (Default = Disabled).

Heuristics Scanning Level - See the description above. 

Do not scan files larger than - See the description  above. 

  • Click 'OK' to apply your changes.

Scheduled Scanning

Click 'Antivirus' > 'Scanner Settings' > 'Scheduled Scanning':

  • The options you set in the 'Scheduled Scanning' tab apply to all your scheduled scans. See this wiki for help to create scan schedules. 

Configure scheduled scan settings

  • Open xcitium Client Security
  • Click 'Antivirus' > 'Scanner Settings'
  • Click the 'Scheduled Scanning ' tab:

The options in this pane are similar to those for manual scanning settings, except for: 

Automatically quarantine threats found during scanning -  See the description  in the ‘real-time scanner settings’ section 

Show scanning progress - Displays a progress bar when a scheduled scan starts. Clear this box if you do not want to see the scan progress status (Default = Enabled).

  • Click 'OK' to apply your changes.


Click 'Antivirus' > 'Scanner Settings' > 'Exclusions'.

  • The exclusions area shows files and paths that you have chosen to skip during virus scans.
  • CCS will not generate an alert for an excluded item, even if the item is rated as malicious in the global blacklist.
  • Items may have been added to this list because you selected 'Ignore' at the scan results window, or because you added them to exclusions at an alert.
  • Use this interface to add or remove exceptions.

Add and manage exclusions

  • Open xcitium Client Security
  • Click 'Antivirus' > 'Scanner Settings' 
  • Click the 'Exclusions' tab:

  • Click the 'Add' button. 
  • There are two ways to choose the application that you want to exclude:

Browse Files... - Navigate to the file / folder you want to exclude in the left pane and move it to the right pane by clicking the right arrow:

Browse Running Processes - Choose the target application from a list of processes running on your PC. The parent file of the process is added to exclusions.

  • Repeat the process to add more exclusions.
  • Click 'OK' to register your exclusions.
