General

The General tab allows you to configure settings to scan workstations and servers by SpIDer Guard.

•Optimal (enabled by default). In this mode, SpIDer Guard scans objects only in the following cases:

▫For objects on hard drives, an attempt to execute a file, create a new file, or add a record to an existing file or boot sector.

▫For objects on removable media, an attempt to access file or boot sectors in any way (write, read, execute).

•Paranoid. In this mode, SpIDer Guard scans all files and boot sectors on hard or network drives and removable media at any attempt to access them (create, write, read, execute). The Paranoid mode ensures maximum protection, but considerably reduces computer performance.

2.The Use heuristic analysis option allows SpIDer Guard to detect suspicious objects that are most likely infected with unknown viruses. By default, this option is enabled. If this option is disabled, only the signature analysis is used for scanning.

3.The Scan for rootkits option allows you to perform the background scanning of the operating system for complex threats and curing active infections when necessary. During the background rootkit scanning, files and folders specified on the Exclusions page are excluded from scanning.

Disabling of SpIDer Guard does not affect background rootkit scanning. If the option is enabled, background scanning is performed regardless of whether SpIDer Guard is running or not.

This setting group allows you to enable scan of certain types of objects and to Block autoruns from removable media. In any mode (optimal or paranoid), objects on network drives and removable media are scanned only if the corresponding options are enabled.

By default, SpIDer Guard performs on-access scans of files that are being created or changed on the hard drives and all files that are opened on removable media, as well as blocking the automatic startup of their active content. This method prevents your computer from getting infected through removable media, as SpIDer Guard monitors your file system accesses in the real-time mode and blocks the execution of malicious code.

Changing a file name within the removable media will not start the SpIDer Guard scanning process. It is not considered a modification, as only the file's metadata is changed, but not the file itself.

Operating system may register some removable media as hard drives (for example, portable USB hard drives). In this case, the Safely Remove Hardware and Eject Media icon is not displayed in the Windows notification area. Unless in paranoid scan mode, SpIDer Guard does not perform scanning when reading a file from such a disk. Scan such devices with Dr.Web Scanner when you connect them to the computer.
