The File Guard not only scans files before they are executed, but depending on your chosen settings, it can also scan before all other file actions such as moving or downloading from the Internet.
The following options are available for customization of the File Guard:
Scan level - The slider control allows you to balance the File Guard's scan level between best performance and best protection as follows:
- Fast - Scans programs when they are started. This option has the least effect on the performance of your system while still ensuring that Malware is prevented from executing. Inactive Malware may remain undetected until you run a manual scan.
- Balanced - Scans all files when they are created or modified, e.g. when a file is downloaded or copied onto your computer from a USB stick. Balanced is the recommended setting.
- Thorough - Scans all files when they are read by any program so that simply selecting a file is sufficient to cause it to be scanned. This option has the greatest impact on system performance and doesn't offer a significant advantage in detection when compared to the other options.
- Only scan files with specific extensions - When this check box is selected, the File Guard only scans files with extensions that are specified in the list. On the one hand this setting can improve the speed of your system because only some files on the hard drive are scanned but on the other hand this also reduces the level of system protection. You can edit the list of specified file extensions by using the Edit button.
You can configure the default actions to take for each of the following types of File Guard detections:
- Malware detections - Choose how you want the File Guard to behave when Malware is detected by selecting either [Alert], [Quarantine silently], or [Quarantine with notification] from the drop down menu.
- PUP detections - Choose how you want the File Guard to behave when Potentially Unwanted Programs are detected by selecting either [Alert], [Quarantine silently], [Quarantine with notification], or [No detection] from the drop down menu.
