Additional information about the protection status of each module, as well as suggested solutions for restoring full protection, are displayed as a notification in the Overview window. To change the status of individual modules, click Setup and select the desired module.


MONITOR_RED The red icon and red Security alert status indicate critical problems.
There are several reasons this status may be displayed, for example:

Product not activated or License expired—This is indicated by a red protection status icon. The program is not able to update after your license expires. Follow the instructions in the alert window to renew your license.

Detection engine is out of date—This error will appear after several unsuccessful attempts to update the detection engine. We recommend that you check the update settings. The most common reason for this error is incorrectly entered authentication data or incorrectly configured connection settings.

Antivirus and antispyware protection disabled—You can re-enable antivirus and antispyware protection by clicking Enable antivirus and antispyware protection.

MONITOR_ORANGE The orange icon indicates limited protection. For example, there might be a problem updating the program or your license may be nearing its expiration date.
There are several reasons this status may be displayed, for example:

Gamer mode active—Enabling Gamer mode is a potential security risk. Enabling this feature disables all notification/alert windows and stops any scheduled tasks.

Your license will expire soon—This is indicated by the protection status icon displaying an exclamation point next to the system clock. After your license expires, the program will not be able to update and the Protection status icon will turn red.
