1 Introduction to Comodo Internet

Security

Overview

Comodo Internet Security offers 360° protection against internal and external threats by combining a powerful Antivirus protection, an enterprise class packet filtering firewall, and an advanced host intrusion prevention system called Defense+.

CIS version 4 sees a major leap forward in security and usability with the addition of the new sandbox feature - an isolated operating environment for unknown applications. Under default settings, unknown applications are now automatically sandboxed so that they cannot make permanent changes to other processes, programs or data on your 'real' system. CIS is also available in Plus, Pro and Complete editions, each offering a range of additional services to the core protection offered by the free version. These include services such us LivePCSupport (Comodo support experts available 24/7 to fix any problem with your computer); TrustConnect (secure Internet proxy service that ensures 128 bit encrypted connectivity from any public wireless hotspot); Online Backup (2GB of online storage space) and the Comodo Guarantee (if your computer becomes damaged as a result of malware and Comodo support services cannot return it to a working condition then we’ll pay the costs of getting it repaired. See terms and conditions for full details. Available to USA residents only).

When used individually, each product delivers superior protection against its specific threat challenge. When used together as a full suite they provide a complete 'prevention, detection and cure' security system for your computer.

www.comodo.com

Comodo Internet Security Features:

• Antivirus - The proactive antivirus system that automatically detects and eliminates viruses, Worms and

Trojan horses.

• Firewall - The Firewall that constantly defends your system from inbound and outbound internet attacks

with a highly effective packet filtering firewall.

• Defense+ - A rules based intrusion prevention system that protects your critical operating system files from

malicious processes, internal attacks and blocks unknown malware before it ever gets a chance to install.

Defense+ now features automated sandboxing of unknown applications. The sandbox ensures untrusted

(but harmless) applications are allowed freedom to operate whilst untrusted (and genuinely malicious)

applications are prevented from accessing or infecting your computer.

• Live PC Support – Tier 1 (Pro version only) - a 24 x 7 support in which Comodo experts remotely access your computer when you need it, for:

• Virus Diagnosis/ Removal;

• PC Tune-up;

• Internet Login Protection;

• Email Account Setup;

• Live PC Support - Tier 1 + Tier 2 (Pro and Complete versions only) - a 24 x 7 online support service in which Comodo experts remotely access your computer when you need it, for:

Virus Diagnosis/ Removal PC Tune-up; Internet Login Protection; Email Account Setup; Software Installation; Printer Setup/ Troubleshooting; Optimizing your computer's power settings; Computer Troubleshooting.

• Secure Wireless Internet Connectivity (Plus, Pro and Complete versions only) - TrustConnect makes

surfing the web safe from any public Wi-Fi location (10 GB per month)

• Comodo Guarantee (Pro and Complete versions only) - If your computer becomes damaged as a result

of malware and Comodo support services cannot return it to a working condition then we’ll pay the costs of getting it repaired. See terms and conditions for full details. Available to USA residents only.

• Online BackUp (Complete version only) - Back-up your important data to Comodo's highly secure

servers. Data is encrypted and can accessed only by the user from any Internet connected computer in the world (2 GB storage space).

Comodo Internet Security can be used ‘out of the box’ - so even the most inexperienced users need not have to deal with complex configuration issues after installation.

Comodo Internet Security alerts you whenever potential malware attempts to attack or gain access to your system. The alerts are displayed as pop-ups at the right hand corner of your screen and allow you to allow or block the unrecognized activities, processes and connection attempts of running applications (CIS now even protects against 'drive-by-download' buffer overflow attacks.) Apart from expert advice in the form of 'Security Considerations', each alert now also features the innovative ThreatCast feature to help users arrive at an informed decision on how to react to the alert. The ThreatCast system allows users to share their responses among the community of millions of CIS users worldwide. Whenever an alert appears, it contains a report of how other users have responded to the same alert. The report provides an additional guidance to even inexperienced users on making a decision to respond to the alert.

Comodo Internet Security - Extended Features

Highly Configurable Security Rules Interface

Comodo Internet Security offers more control over security settings than ever before. Users can quickly set granular Internet access rights and privileges on a global or per application basis using the flexible and easy to understand GUI. This version also sees the introduction of preset security policies which allow you to deploy a sophisticated hierarchy of firewall rules with a couple of mouse clicks.

Application Behavior Analysis

Comodo Internet Security features an advanced protocol driver level protection - essential for the defense of your PC against Trojans that run their own protocol drivers.

Event logging

Comodo Internet Security features a vastly improved log management module - allowing users to export records of Antivirus, Firewall and Defense+ activities according to several user-defined filters. Beginners and advanced users alike are greatly benefited from this essential troubleshooting feature.

Threatcast Functionality

Comodo Internet Security provides a report on how the others among millions if its users have reacted to each of its pop-up alerts generated during different circumstances. This provides guidance to make a decision on allowing or blocking an activity that has generated the alert. Comodo Internet Security has a savvy and technically knowledgeable user base. Therefore, the responses of our intelligent user base are help to guide the novice users who do not know how to react. Once signed up, your responses are also uploaded to the servers to guide others.

Memory Firewall Integration

Comodo Internet Security includes the buffer-overflow protection of Comodo Memory Firewall. On the attempt of a buffer overflow attack, CIS raises a pop-up alert. This provides protection against data theft, computer crashes and

www.comodo.com

system damage, which are possible consequences of a buffer overflow attack.

'Training Mode' and 'Clean PC' Mode

These modes enable the firewall and host intrusion prevention systems to automatically create 'allow' rules for new components of applications you have decided to trust, so you won't receive pointless alerts for those programs you trust. The firewall learns how they work and only warn you when it detects truly suspicious behavior.

Application Recognition Database (Extensive and proprietary application safe list)

The Firewall includes an extensive white-list of safe executables called the 'Comodo Safe-List Database'. This database checks the integrity of every executable and the Firewall alerts you of potentially damaging applications before they are installed. This level of protection is new because traditionally firewalls only detect harmful applications from a blacklist of known malware - often-missing new forms of malware as might be launched in day zero attacks.

The Firewall is continually updated and currently over 1,000,000 applications are in Comodo Safe list, representing virtually one of the largest safe lists within the security industry.

Self Protection against Critical Process Termination

Viruses and Trojans often try to disable your computer's security applications so that they can operate without detection. CIS protects its own registry entries, system files and processes so malware can never shut it down or sabotage the installation.

Sandboxing as a security feature

Comodo Internet Security's new sandbox is an isolated operating environment for unknown and untrusted applications. Running an application in the sandbox means that it cannot make permanent changes to other processes, programs or data on your 'real' system. Comodo have integrated sandboxing technology directly into the security architecture of CIS to complement and strengthen the Firewall, Defense+ and Antivirus modules.

Submit Suspicious Files to Comodo

Are you the first victim of a brand new type of spyware? Users can help combat zero-hour threats by using the built in submit feature to send files to Comodo for analysis. Comodo then analyzes the files for any potential threats and update our database for all users.

1.2 System Requirements

To ensure optimal performance of Comodo Internet Security, please ensure that your PC complies with the minimum system requirements as stated below:

• Windows 7 (Both 32-bit and 64-bit versions), Windows Vista (Both 32-bit and 64-bit versions) or Windows

XP (Both 32-bit and 64-bit versions)

• Internet Explorer Version 5.1 or above

• 128 MB available RAM

• 210 MB hard disk space for both 32-bit and 64-bit versions

www.comodo.com

1.3 Installation

Before you install Comodo Internet Security, read the installation instructions carefully and also review the system requirements. Additional services and features such as activation of your LivePCSupport account and/or Comodo Guarantee are carried out after the base installation has been completed.

Please note - the CIS software itself is identical for all customers regardless of the package type. All versions (including free) include all security features, technologies and updates. The difference between the package types lies in the availability of additional services such as LivePCSupport, TrustConnect, Online Storage and the Comodo Guarantee. Activation of additional services is carried out after the base installation has been completed.

1.3.1 Installation Process

To install, download the Comodo Internet Security setup files to your local hard drive. (setup.exe can be downloaded from http://www.personalfirewall.comodo.com)

Next, double click on the setup file to start the installation wizard and follow the process as shown below.

STEP 1: Select your installation language

Firstly, choose the installation language.

The language you choose here will determine the language you see during the rest of the installation process and in all areas of the CIS 4 interface. Use the drop down to make your selection.

STEP 2: License Agreement

To continue with the installation, you must read then accept the End User License Agreement (EULA).

www.comodo.com

Click 'I Accept' to agree to the terms and continue.

STEP 3: Product Registration

Next, the wizard will activate your free lifetime license. If you wish to sign up for news about Comodo products, updates and offers then enter your email address in the space provided. This is optional. Click 'Next'.

www.comodo.com

STEP 4: Select which components you wish to install

The next step is to choose which elements you would like to download and install. Details on each product can be viewed in the right hand pane.

www.comodo.com

In order to obtain maximum protection, Comodo recommends that you uninstall any third party personal Firewall and Antivirus in your system and select both the Comodo Antivirus and Comodo Firewall options (installation of both is mandatory for Plus, Pro and Complete customers). CIS Plus, Pro and Complete customers will also need to install Comodo TrustConnect to take advantage of the service (this is optional for users of the free product). Comodo HopSurf and Comodo Time Machine are optional installations for all users.

• Install COMODO Firewall - Selecting this option installs Comodo Firewall and Defense+ components. De-

select this option, if you already have third party Firewall protection activated in your computer system. Installing Comodo Firewall is a mandatory requirement if you are a Plus, Pro or Complete customer. If you choose to install the firewall BUT NOT the antivirus then you will be asked to configure the firewall security settings in Step 5

• Install COMODO Antivirus - Selecting this option installs Comodo Antivirus and Defense+ components.

De-select this option, if you already have a third party virus protection activated in your computer system. Installing Comodo Antivirus is a mandatory requirement if you are a Plus, Pro or Complete customer.

• Install COMODO HopSurf - Selecting this option installs the Comodo HopSurf browser toolbar to provide

fingertip access to the world's most exciting social network. This is optional for all users.

• Install COMODO TrustConnect - Selecting this option installs the client for Comodo's secure proxying

service - ensuring all wireless connections from public hotspots are encrypted and secure. This is optional for free users and necessary for Pro, Plus and Complete users that wish to use the service.

The lower part of the dialog indicates the location on your hard drive that the files will be download to; the current size of the download based on the choices you have made and the amount of space you have available on the drive to which you have decided to download. The installation process will vary slightly depending on the choices you make here. Once you have made your choices, select 'Next to begin downloading the required components:

www.comodo.com

Once downloaded, the installation process will automatically begin and you will be asked to choose which folder to install to. If you do not wish installation to begin immediately after downloading is complete, then check the box 'Do not install the packages after downloading.'

The default installation folder is C:\Program Files\COMODO\COMODO Internet Security.

If you do not wish to install Comodo Internet Security in the default location, click Change and select a different folder for installation. Click 'Next' to install to the desired folder.

Step 5: Firewall Configuration

If you chose not to install the antivirus component then you are provided with the opportunity to set the security level of the Firewall. This option should only be chosen when you have a third party Antivirus protection activated in your system. If this step does not apply to you then click here to skip to step 6.

www.comodo.com

The options available are;

Firewall only - This option is only recommended for experienced firewall users that have alternative Host Intrusion Prevention software installed on their systems. Selecting this option will install ONLY the packet filtering network firewall and not Defense+ (Defense+ is essential for blocking malicious software like worms and Trojans from making outgoing connection attempts). This isn't to say this option is an unwise choice (the network firewall is one of the strongest available - offering highly effective and configurable inbound and outbound protection) but it is important to realize that, on it's own, it does not offer the host intrusion protection as afforded by Defense+.

Firewall with Optimum Proactive Defense - Selecting this option will install the packet filtering Comodo Firewall with Defense+. Defense+ is installed with optimum protection settings. This also sets the default configuration for security settings to optimum level. Click here for more details on default protection level.

Firewall with Maximum Proactive Defense - This is the most complete option and offers the greatest level of security. Selecting this will install Comodo Firewall with Defense+. Defense+ settings are set to the highest protection levels. This also sets the default configuration for security settings to maximum level. Click here for more details on default protection level.

Select the option of your choice and click Next. The installation moves to Step 6.

STEP 6: Configure Comodo Threatcast

The Threatcast feature in Comodo Internet Security allows you to share your responses to CIS alerts - the decisions made on whether allowing or blocking requests or activities, among the community of millions of CIS users worldwide. The responses of every Threatcast user to this specific alert are collated - enabling you to see how others have reacted as a percentage bar chart in the alert pop-up itself. This will provide an additional guidance to you to make a decision on responding to the alert. Comodo Internet Security has an experienced and technically knowledgeable user base and the responses of our intelligent user base can help guide novice users

www.comodo.com

who may be unsure of how to react.

To join the Threatcast Community, select I would like to join Threatcast community and click Next. Otherwise, select I do NOT want to join the Threatcast community and click Next. You can change this setting even at a later time by accessing Miscellaneous > Settings > Threatcast

STEP 7: Configuring your DNS Settings

Comodo Secure DNS service replaces your existing Recursive DNS Servers and resolves all your DNS requests exclusively through Comodo's proprietary Directory Services Platform. Comodo's worldwide network of redundant DNS servers provide fast and secure Internet browsing experience without any hardware or software installation. In this step of installation of Comodo Internet Security, the DNS settings of your computer can be changed automatically to direct to our DNS servers. You can disable the service at anytime and revert to your previous settings.

www.comodo.com

To enable the Comodo Secure DNS Service, select I Would like to use Comodo Secure DNS Servers and click Next.

For more details on Comodo Secure DNS Service and to know how to enable or disable the service, refer to

Appendix 1 Comodo Secure DNS Service.

Step 8: Configuring your browser

The next step allows you to configure your browser settings, to have www.hopsurf.com as the homepage for your default browser and Ask.com as your default search provider.

www.comodo.com

Step 9: Installation and restarting your computer

After completing the configuration options to your satisfaction the setup wizard will ask for confirmation before commencing the installation procedure. Click the 'Back' button to review and/or modify any of settings you have previously specified. To confirm your choices and begin the installation of Comodo Internet Security, click 'Install'.

www.comodo.com

After installation is complete, you must restart your computer for CIS to become active.

Please save any unsaved data and click 'Yes' to restart the system. If you want to restart the system at a later time, click 'No'.

Note: The installation will take effect only on the next restart of the computer.

Step 10: After restarting Your System

After restarting, if your computer is connected to a home or work network, then you are prompted to configure it at the 'New Private Network Detected!' dialog:

www.comodo.com

Step 1: Even home users with a single computer have to configure a home network in order to connect to Internet. (this is usually displayed in the Step 1 text field as you network card). Most users should accept this name.

Step 2: If you wish your computer to accept connections from other PC's in this network or for printer sharing, then also check this option (e.g. a work or home network).

check mark to the right of the license key fields (shown above). If your key is not accepted then please double check that you copied and pasted the entire key correctly.
