The User Interface – In Detail

Most messages and controls can be found in the system task bar or directly above the task bar. If you choose to open the UI, of course, you can place that anywhere, or minimize it. But Cerberus is working even if the UI remains closed.
When SigFree Cerberus first starts, in the lower right corner of your screen, attached to the Cerberus three-headed dog icon, you’ll see:
From that point on, Cerberus is working and protecting your system. Even if you exit Cerberus, it continues to protect, unless you choose to shut it off.
Right click on the icon and the pop up controls will display:
Help – takes you to
Open – will open the UI
Set Filtering – provides three options,
1. On = normal operation, full protection mode.
2. Simulate = Will show you what is happening, but Cerberus will take no actions, such as quarantining a suspect.
3. Off = Cerberus is off, it is no longer listening to communications and will of course take no actions.
The About selection displays the version you are using. The version number here is the public release version.
Clicking Open will open the UI, shown below. The Help drop down menu includes:
About = same as explained above
View Release Notes = A quick read about Cerberus
Context Help = Only for license screens, clicking F1 will take you to the correct topic.
Help Topics = takes you to

Above, the On, Simulate and Off controls are as explained previously. We’ll go through Customize shortly, but first,

Clicking License yields the following window. This displays your license status on the second line. This screenshot was of a licensed computer and it’s showing that the v1.0 license is in good standing. The v1.0 license has no time limit and so none is displayed. If this were a 2 week trial screenshot, it would show, “You have x days left on your trial license”. Whatever your license status, it will be shown on this screen.

  • Purchase License will take you to the Digital River order page.
  • Go to Cerberus Site takes you to the home page.
  • Go to Help & FAQs will take you to
  • user

    Clicking “Enter License Key” displays the following window. The Machine ID and the license key are not shown. The license key you enter is actually not stored on your computer. The key segments shown here would be the last part of the license key you entered. The majority of the key is modified based on characteristics of your computer and is also encrypted.
    If this were a trial license and you had purchased a license key, this is where you would enter that key which you would receive by email after purchasing the license. A valid key will be recognized and approved almost immediately.


    Buy Now will take you to the home page where you’ll find purchase links. See the red window below. Simply click on the Purchase Your v1 License. We’ll alter the Buy Now button on the program UI window in a future revision to go directly to the Digital River order page.


    Now, we’re going to run a piece of synthetic malware named “FooledYou” that runs at variable speeds and then tries to go very slow to avoid #whobenefitsdetection. As Cerberus detects it, it displays the following message – this message indicates it is containing and analyzing the suspect. To contain means that Cerberus is not allowing its messages to leave your computer.
    FooledYou now stops misbehaving and through its analysis, Cerberus determines it is no longer a threat. So, Cerberus provides the message that it has relaxed. In other words, it has released FooledYou from containment.
    Now, take a look at the UI below. Each time FooledYou tried to start sending out illegitimate messages, Cerberus contained it. But FooledYou stopped sending messages and Cerberus relaxed it two more times. The fourth time it was contained and tried to send out illegitamate messages very slowly. Cerberus maintained containment and determined that FooledYou had to be quarantined.Note that at no time was FooledYou doing its dirty work that Cerberus did not either contain it temporarily or quarantine it.
    Now we have a good reason to click on Customize and go to the below window. It shows that FooledYou is quarantined. From this window, if a user wishes to make decisions about any process, they may do whatever they wish. Or, they can simply take Cerberus’ word for it.
    If we highlight FooledYou as shown in the window below, We can now either click Remove Exception and FooledYou will be released from quarantine. This is not dangerous. Even if FooledYou mutates, if it starts becoming a threat again, it will simply be quarantined again. If we believe FooledYou is mistakenly quarantined and don’t want it to be quarantined again, we would simply click Exempt Selected and it will be moved up to the Exempt section with a green symbol. But never do this unless you’re sure. In this case, FooledYou is malware, although it is a synthetic example, and was only run within our test network. All computers in the network have been cleaned and all copies of FooledYou redacted and destroyed. But if you find a program you trust that you never want to be scanned and possibly contained, you can do so.
    In this case, we click Add New Exception and your file folders will appear as shown below. Navigate to the executable you want to exempt and highlight it. Click open, and it will be listed in the Exemptions window as an exempt program with a green symbol. Cerberus will ignore any program you enter here.
    In the use interface shown below, we can see that the process we selected has been recorded as an exempt program and it was exempted at 9:25:55PM on 15 October 2014. We used the Cerberus uninstall program as an example here, only to avoid using anybody else’s program as an example. But please don’t do this to any of the Cerberus program files.
    We hope that step by step approach is helpful to you. If you would like to read more about user interface design, here’s a good starter page. Please also note the graphical description below which is from the same url.
