Description

Most antivirus software do not scan ULead® Photo Express® Saved Image (UPX) files, archive files, and compressed files. Hackers often take advantage of this fact and hide malicious code in these types of files. The powerful File Anti Virus monitor of ‘e Scan uses ODS with Cache Technology to scan your computer. It scans individual files, archives, and self-extractor files, such as ZIP files, CAB files, RAR files, and ACE files for malicious software and thus prevents any malware from infecting your computer. In addition, the File Anti-Virus monitor constantly checks files and scans them for unauthorized changes whenever they are accessed or modified.

When you select the File Anti Virus icon, the tabbed page provides you with information regarding its status, options for configuring the module, and links to reports on the recent scans performed by the module.

The tabbed page shows two sections: Configuration and Reports. These two sections are described as follows:

Configuration

This section provides you with information regarding the status of File Anti Virus and proactive scan. It also shows you the default action that File Anti Virus will perform when it detects a malicious object.

This section displays the following information.

File Anti Virus Status : It shows whether File Anti Virus is running or not.
Proactive Scan Status : It displays whether proactive scanning is enabled or not.
Action : It shows the action that ‘e Scan will perform when a malicious object is detected by File Anti Virus.

In addition, you can configure the following settings.

Start/Stop - This link enables or disables the File Anti Virus module. You can easily switch File Anti Virus from the start state to the stop state and vice versa by using this link.

Settings - This link opens the File Anti Virus Settings dialog box, which helps you configure the File Anti Virus module for real time monitoring.

The File Anti Virus Settings dialog box This dialog box has two tabs: Objects and Options . These tabs are described as follows:

I. Objects This tab displays the available drives on the computer. It allows you to configure the actions that File Anti Virus should perform when it encounters a security threat during the scan operation.

This tab is divided into two panes, they are described as follows.

The left pane :- This pane displays all the removable and non removable drives, network drives, installed drives, and mapped drives that File Anti Virus can monitor or scan. All the drives displayed on the left pane are selected by default.

The right pane :- This pane 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.

A. Action 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 described as follows:

Report Only – If you select this option, File Anti Virus only displays a message informing you about the virus infection; it does not take any action on the infected object.
Disinfect – [Default] This option is selected by default. For best results, you should keep this option selected. If you select this option, File Anti Virus cleans the infected object.

Make backup before disinfection option – At times, File Anti Virus may find that a system file is infected and deleting the file may cause the operating system to become unstable. By selecting this check box, you can ensure that ‘e Scan creates a back up of the infected file in a non executable format before it cleans or deletes the file.

Note: It may not always be possible to clean an infected file. In such cases, antivirus software often quarantine or delete the infected file. With ‘e Scan, you can configure File Anti Virus to quarantine, delete, or only alert you regarding the status of the infected files after ‘e Scan has found that they cannot be cleaned.

If disinfection is impossible - You can configure File Anti Virus to perform any one of the following operations if it is unable to clean an infected file.

Report Only - When you select this option, File Anti Virus only reports that the infected object cannot be cleaned; it does not take any action on the object.
Quarantine Object - [Default] When you select this option, File Anti Virus quarantines the infected object.
Delete Object - When you select this option, File Anti Virus deletes the infected object.

Quarantine Object - When an infected file is quarantined, it is moved to an area of the memory from where it cannot cause any harm to the existing files or programs. You should select this option when you need to prevent other files or objects from accessing the infected object without actually deleting it.
Delete Object - If you select this option, File Anti Virus will delete the infected object.

B. 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.

C. Scan local hard disk drives - [Default] You should select this check box if you need to scan all the local drives attached to the computer.

D. Scan network drives - [Default] You should select this check box if you need to scan all the network drives, including mapped folders and drives, attached to the computer.

E. Scan files of following types - You should select this option if you need to scan files of the types listed under the following categories.

All Infectable - [Default] If you select this option, File Anti Virus scans only the predefined objects in the list of files or objects that are prone to infection as per the ‘e Scan’s virus signature database.
All - If you select this option, File Anti Virus scans all the files and objects in the computer.
By Mask - If you select this option, File Anti Virus scans all the file types listed in the Scan file types by mask dialog box. ‘e Scan provides you with a list of default files and file types. You can add more items to this list or remove items as per your requirements.

You can add the names of riskware, such as remote admin software, to the riskware list in the Not a virus list dialog box by double-clicking the Add / Delete option if you are certain that they are not malicious. However, this list is empty by default. You can add programs to this list if you are certain that they are not malicious.
