File Anti-Virus



File Anti-Virus is a part of the eScan’s Protection feature. This module monitors and safeguards your computer on a real-time basis from all kinds of malicious software as files are accessed, copied, or executed. This module includes the Proactive Scanning feature, which helps you to block applications that perform suspicious activities. File Anti-Virus also includes the Block Files feature. This feature allows you to block or quarantine files from being accessed from local or network drives. In addition, File Anti-Virus also allows you to enable Folder Protection, which prevents users from creating, deleting, or updating files or subfolders within specified folders.

There are four tabs – Objects, Options, Block Files, and Folder Protection, which are as follows:

Objects

This tab provides you with a number of settings for fine-tuning the File Anti Virus module as per your requirements. For example, you can configure module to scan specific storage devices or exclude files of a given file type.


  • Actions in case of virus detection: This section lists the different actions that File Anti Virus can perform when it detects a virus infection. These actions are Report only, Disinfect, Quarantine, and Delete object. Out of these, the Disinfect option is selected by default. By default, the quarantined files are saved in C:\Program Files\eScan\Infected folder
  • Scan local removable disk drives: [Default] You should select this check box if you need to scan all the local removable drives attached to the computer.
