SharePoint 2013 Or 2016: Configure Antivirus Settings And Features

This article will teach you about SharePoint Antivirus settings and features. I will explain how to use Antivirus for SharePoint server.

If we have configured SharePoint server either in a single farm or multi-tier farm, we need security for both of those. So by default, SharePoint server will not protect us from viruses in the farm, like if someone is uploading any data it will not check for viruses or anything, it will directly upload it.

We can activate antivirus events only after installing a compatible antivirus scanner. In a server farm, we must install antivirus software on the server in case we have a multi-tier farm, then we need to install it in the Web front-end server in the server farm.

Below are the steps to configure the security and use their features in SharePoint:

  • Open SharePoint Central Administrator with administrator rights

  • Central Administrator page will displayed at browser page, here we need to select security option from left side of the page.

  • Once you have clicked on security page, it will redirect us to security wizard where many options will be available. Here we need to select Manage Antivirus option from General security; shown below,

  • Once you have clicked there, we will get Antivirus page where we need to do configuration and settings for the same,

  • We can see there will many options available on this page, below I have described each one,

  • Antivirus settings
    will specify the behavior while uploading documents in the list or Library. Following option will be available for those.

  • Scan documents on upload
    by selecting this setting to scan uploaded documents. This helps prevent users with infected documents from allocating them to other users in the farm.

  • Scan documents on download
    This feature is specified to prevent users from downloading infected documents by warning them about infected files. If they wish to download after notification it will allow Users to still choose to download infected files, if the file or document that is not affected with virus documents is not selected.

  • Allow users to download infected documents
    If this option will be selected it will allow users to download infected documents. By default this setting will be selected for SharePoint anti- virus. I don’t recommended always keeping this option deselected (clear checkbox).

  • Attempt to clean infected documents
    Select this setting to automatically clean infected documents that were discovered during scanning the uploading any file.

  • Antivirus Time Out
    In the Time out duration (in seconds) box, type a value for how long to wait for the virus scanner before timing-out. Maximum we can put is 999 (seconds).

  • Antivirus Threads
    This is for Number of threads box, type a value for the number of threads that the virus scanner can use. In this section also max value allowed is 999.

By Default setting for Antivirus

We can modify this setting as per our requirement also, see the below screen after modification of the anti-virus setting,
