Configuring Files and Programs Scanned by Antivirus

This Article Applies to:

  • AVG Business Cloud Console
  • AVG Business On-Premise Console

You can configure the types of files and programs that are scanned by AVG Business Antivirus when you set up the scan task, assuming you selected an Advanced Scan type (Custom, Boot-time). Therefore, the main details for what will be scanned are not configured in policies, though exclusions are. For more information on scan tasks, see Device Scanning Tasks.

Types of Scans

  • Quick Scan—Scan for common threats
  • Full System Scan—Run a detailed scan of every file on the device
  • Removable Media Scan—Scan USBs and portable media connected to the device
  • Custom Scan—Run a scan where you choose the file types, sensitivity of the scan, performance, actions, and whether compressed files are included.
  • Boot-time Scan (MS Windows only)—Run a scan when the device boots up.

Cloud Console

Scanning Devices

For details on how to create one-time tasks for specific devices or your entire network, see Creating and Deleting Tasks.

  1. Click Scan device.
  2. Select a type of scan:
    • Quick Scan—Scans for common threats
    • Full System Scan—Runs a detailed scan of every file on the device
    • Removable Media Scan—Scans USBs and portable media connected to the device
    • Custom Scan—Runs a scan where you choose the file types, sensitivity of the scan, performance, actions, and whether compressed files are included.
    • Boot-time Scan (MS Windows only)—Runs a scan when the device boots up.
    • If you chose Custom or Boot-time Scan, select the additional configuration options for your scan. For more information see Configuring Files and Programs Scanned by Antivirus.
  3. If you would like the task to be recurring, select Schedule the scan and set the Frequency (one-time, daily, weekly, or monthly) and Schedule start date and time.
  4. Type a Custom name for the scan.
  5. Click Start Scan.

Any threats that are detected during this scan are usually sent to the device's Virus Chest. You can view and manage these detections in Device Details. For more information see Resolving Threat Detections.

Scan Configuration

Configuring Boot-Time Scans

Boot-time scans are only available for Microsoft Windows devices, and will scan your device when it is just beginning to "boot up".

Windows locations to scan: you can select preset locations to scan from the drop-down menu, which are then added to the list. If desired, you can also type the path to a specific location to be included in the scan. Any locations you do not want included in the scan can be removed from the list by clicking the delete button.

Restart the device now: immediately restart the device in order to perform a boot-time scan. If you do not check this, the boot-time scan will run the next time the device restarts.

Notify users with a message before the restart: enter a message to be displayed to the end user notifying them the device will restart shortly

Specify when the above message will be displayed: select when the message will be displayed, between 1 minute, 10 minutes, 30 minutes, or 1 hour before restart.

Heuristics: heuristics enable Antivirus to detect unknown malware by analyzing code for commands that may indicate malicious intent. The default setting is Normal. With higher sensitivity, Antivirus is more likely to detect malware, but also more likely to make false-positive detections that incorrectly identify files as malware.

PUP and suspicious files: choose whether or not to scan for Potentially Unwanted Programs (PUPs)

Unpack archive files: choose whether or not to unpack archive file types during scanning, which is slower but more extensive

When a threat is found: choose what action AVG takes when a threat is detected, between Clean automatically, move to chest, repair, delete, or no action.

Cancel the scan on the workstation: choose whether or not the scan can be canceled on the workstation while it is running

Configuring Custom Scans

Custom scans provide the most control over what specific types of files, folders, programs, and processes are included in the AVG Business Antivirus scan. You can select different scan options for Windows Workstations, Windows Servers, and MacOS X Devices within the same scan task.

Configuring Locations

You can select preset locations to scan from the drop-down menu, which are then added to the list. If desired, you can also type the path to a specific location to be included in the scan. Any locations you do not want included in the scan can be removed from the list by clicking the delete button.

File Types Tab

You can choose whether or not to scan all files (or just the most common areas for threats). Additionally, you can configure the scan to recognize file types by their content, which requires scanning the entire file, or by their name extension which will only scan the files with the extensions you enter in the text box that appears when that option is selected.

Sensitivity Tab

Heuristics Sensitivity: Heuristics enable Antivirus to detect unknown malware by analyzing code for commands that may indicate malicious intent. The default setting is Normal. With higher sensitivity, Antivirus is more likely to detect malware, but also more likely to make false-positive detections that incorrectly identify files as malware. Code emulations unpack and test suspected malware in an emulated environment where the file cannot cause damage to devices. Use code emulation is enabled by default.

Sensitivity: choose to test whole files, which will cause the scan to be slower but more extensive.

PUP and suspicious files: choose whether or not to scan for Potentially Unwanted Programs (PUPs)

Links: choose whether any links within files are followed during the scan, which will cause the scan to be slower but more extensive.

Performance Tab

Priority: choose the priority of the scan on the end device(s). A higher priority will lead to a quicker scan, but will use more resources.

Persistent cache: choose whether to speed up the scan by using the persistent cache, and/or to store data about scanned files in the persistent cache which will slow down the scan.

File access: choose whether to speed up the scan by reading files in the order they are stored on the disk, which is only effective on NTFS volumes.

Actions Tab

Apply an action: choose whether or not actions are automatically taken during the scan when a virus, potentially unwanted program (PUP), or suspicious file is detected. The options are Clean Automatically, Move to chest, Repair, Delete, and No Action.

If, for whatever reason, AVG cannot complete the main action, it will attempt the action selected under If the action fails, use

Options: choose whether to perform the selected action upon restart.

Processing of infected archives: choose whether to only remove the packed file from the archive (and if that fails, do nothing), remove the packed file from the archive (and if that fails, remove the entire archive), or to remove the entire archive.

Packers Tab

Choose whether or not to extract all archive files for scanning.
