Manage main settings

  • Show Avast tray icon: adds the Avast icon to the system tray on your Windows taskbar. When you click the Avast tray icon, you can quickly access useful actions, such as opening the Avast user interface or updating the program version and virus definitions. The warning triangle on the icon indicates that you are not fully protected. The Avast icon is enabled by default.
  • Animate the icon when scanning: animates the Avast tray icon on your Windows taskbar to notify you when a scan is running. This option is disabled by default.
  • Show SecureLine VPN tray icon: adds the SecureLine VPN icon to the system tray on your Windows taskbar. The SecureLine icon is enabled by default.
  • Enable reputation services: allows you to anonymously contribute technical information based on the prevalence of risky files which helps us to better identify malware threats. This option is enabled by default. For more information, read Avast Privacy Policy.
  • Enable CyberCapture: uses the CyberCapture feature to detect and analyze rare, suspicious files. If you attempt to run such a file, CyberCapture locks the file from your PC and sends it to the Avast Threat Labs where it's analyzed in a safe, virtual environment. You are notified when the analysis is complete. This option is enabled by default.
    • Always block it: immediately blocks potentially malicious files and sends the files to Avast Threat Labs. This option is selected by default.
    • Allow me to decide: sends you a notification before a file is submitted to Avast Threat Labs.
    Note: We recommend to keep the default settings enabled unless you are aware of the potential risks.
  • Enable Hardened mode: uses information based on reputation services to determine which executable files are safe to open. You can choose between two modes:
    • Moderate: blocks only files which have bad ratings or no rating at all. All other files are allowed to run.
    • Aggressive: only chosen files with known high ratings are allowed. All other files are prevented from running.
    Note: Hardened mode is disabled by default. We recommend that only novice users tick this option.
  • Scan for potentially unwanted programs (PUPs): scans for PUPs and sends a notification if any are detected. PUPs are stealthily downloaded with other programs and typically perform unwanted activity. When you receive a notification, you can decide what to do with the detected program. This option is disabled by default.
  • Silent Mode: prevents Avast popups (including critical alerts) from interrupting full screen applications. This option is disabled by default. We recommend to enable it only temporarily while running an application in full screen.
  • Enable Avast email signature: enables the Avast email signature at the bottom of your outgoing emails to inform your recipients that the email has been scanned for malware. This option is enabled by default and applies only to mail clients (such as Microsoft Outlook and Mozilla Thunderbird).

Adjust sounds

Tick Enable Avast sounds to select event(s) during which you want to be alerted with a sound or voice message.

  • Threat detected
  • Suspicious item detected
  • Potentially unwanted program (PUP) detected

Tick Use voiceover sounds (when available) to play a voice message notification for events, for example when a threat is detected or virus definitions are updated.

Note: All sound settings are enabled by default.

Manage popups

You can manage the behavior of Avast popups using the options below.

  • Show popup offers for other Avast products: sends notifications about others ways you can improve your protection. You can disable this option only if you use a paid version of Avast Antivirus.

    • Info popups: displays notifications about general Avast activity.
    • Update popups: displays information about program and virus definitions updates.
    • Warning popups: displays warnings about possible risks, such as opening an unknown file.
    • Alert popups: notifies you about threats detections and other important incidents.

All popups in the above list are set to 20 seconds by default. If you do not want to see popup messages from the above list, you can set the duration time to 0 for each popup type or enable Silent Mode in the main settings section.

  • Quarantine: allows you to specify the maximum amount of space (in MB) the Quarantine uses on your PC, and the maximum size of any file (in KB) that is sent to the Avast Threat Labs.
    • Maximum size of chest: Files that exceed this limit (256 MB by default) or the remaining space cannot be added to the Quarantine.
    • Maximum size of file to be sent: Files that exceed this limit (16384 KB by default) cannot be submitted to the Avast Threat Labs.

Exclude files or websites from scanning

In the Exclusions panel, you can exclude certain files, folders, or URLs from scanning. While it is generally not recommended, you may want to exclude certain files or websites from scanning, for example if you want to speed up your scans or to avoid false positive detections.

  3. Click OK.

To add another item to the list, select the appropriate tab and click Add. To remove an item, click the relevant row in the appropriate tab then click Delete.

Exclusions created in the File paths and URLs sections apply globally to all antivirus scans and shields. To exclude files only from a specific antivirus scan or shield, use the Exclusions section in the settings of that particular antivirus scan or shield.

Note: Set exclusions only if you know that the files and websites you want to exclude are not infected.
