Comodo Internet Security
Comodo Internet Security is the awarding winning and free security solution for Windows that uses a powerful combination of antivirus, firewall, auto-sandbox, host intrusion prevention and website filtering to immediately protect your computer from all known and unknown malware. Our real-time scanner constantly monitors your computer for threats, protecting you from the moment you start Windows. Our cloud-based scanner uses real-time virus blacklists, so you don't have to download updates before you receive protection against newly discovered threats. Did you know traditional antivirus software can only detect around 40% of the viruses in circulation? The other 60% of viruses are allowed to run because they are 'unknown' to antivirus software. Comodo Internet Security protects you against this other 60% by automatically isolating all unknown files in a secure container called the sandbox. Applications in the sandbox run with restricted privileges, write to a virtual file system and registry, and are not allowed to access other processes or your private data. This means any potential new malware is securely locked away instead of being allowed to run amok as it would in other antiviruses. Our Secure Shopping feature provides the next-generation of security for online banking and shopping. Under Secure Shopping, websites will open inside a virtual environment which is isolated from the rest of your system, so nothing you download can infect your computer. No other processes are allowed to interfere with your browser, and your online session also benefits from SSL certificate checking, key-logger protection, website filtering, screen-shot blocking and remote connection prevention. This creates a direct, threat-resistant tunnel between you and your target website which cannot be hacked by malware or online thieves. Whether you are an IT novice or an experienced user, Comodo Internet Security is the ultimate protection against today's dangerous online world.

FAQ for Comodo Internet Security
1. What makes Internet Security better than my current Antivirus and Firewall combo?
Internet Security is a security suite plus. More than just an antivirus program, it also includes an award-winning firewall, host intrusion prevention, a sandbox for untrusted software, anti-malware and buffer overflow protection to deliver comprehensive protection against today's diverse range of threats.
2. What makes Comodo's Internet Security product different from the others?
It's simple: prevention-based, Default Deny Protection. It works by only allowing trusted files to run on your system. Files that are not trusted are run inside the new sandbox
3. What is the sandbox and how does it protect me?
The sandbox is a virtual operating environment created within your computer for unknown and untrusted programs. Internet Security automatically runs untrusted programs in the sandbox where they cannot make changes to processes, programs or data on your 'real' system. This protection goes well beyond traditional Antivirus software by ensuring any brand new viruses are completely isolated and cannot cause damage.
4. Will programs run OK in the Sandbox?
Yes. Applications in the sandbox are run under a carefully selected set of privileges and will write to a virtual file system and registry instead of the real system. This means untrusted (but harmless) applications have the freedom to operate as usual while malicious programs are prevented from accessing or infecting your computer. This provides smoothest and most secure user experience possible.
5. Do programs stay in the Sandbox forever?
No the sandbox is the first part of a trust decision engine. After an unknown application has been placed in the sandbox, Internet Security will also automatically queue it for submission to Comodo labs where it will be analyzed by our technicians. If it is found to be harmless then it will be added to the global safe list that will be downloaded by all Internet Security users in the next round of updates. Once it is added to the safe list, the application will no longer be run in the sandbox by Internet Security. If it is found to be malicious then it will be added to Comodo's list of malware signatures and will be deleted after the next round of updates.
6. Can I install only the Firewall or only the Antivirus?
Yes you are given the option to install exactly the components you want during setup.

Viruscope
This is a self contained system that helps to alert the user if there is any suspicious activity that is going to intrude the normal computer operations. It has the ability to reverse any possible nefarious actions of software without blocking the software completely. It is more of a specific control that helps the legitimate software to function correctly.Viruscope allows the software to detect, block and undo many potentially unwanted actions.
Website Filtering
This is a provision that makes users more convenient to allow or obstruct access to certain websites. Each user can tailor the website access rules as per their requirements. This feature is best suitable for both home and work environments. For instance, at home, parents can block certain websites that are inappropriate for their kids and at work, the organization can restrict the employees from visiting social media websites during working hours.

What is an Antivirus
and Why do I Need One?
Antiviruses are powerful pieces of software designed to detect, stop, and remove malware from computers. With vulnerabilities constantly emerging in operating systems, browsers, add-ons, and other programs, an antivirus is an essential security component for home users.
How Does Antivirus Software Work?
Whenever you download or launch a file, an antivirus program scans the file for malware. Most modern antivirus programs feature multiple scanning detection processes. The most basic detection process is known as specific detection. This is what most people think of when they think about how an antivirus works. Specific detection works by scanning a file for a specific set of characteristics and checking these characteristics against a known list of malware. This process is executed quickly and is an essential feature of an antivirus software, but it is also easy for cybercriminals to evade. Like a wanted outlaw in the old west, a cybercriminal can disguise a piece of malware to avoid detection. Modify the code slightly, and the malware is rendered undetectable.
Comodo Antivirus also uses heuristic detection and containment to ensure that even unknown malware cannot compromise our users’ computers. Heuristic detection describes the method of analyzing the code of a file to determine if it contains code commonly found in malware. If suspicious code is detected then the antivirus deletes the file or recommends it for containment. Files run in Comodo containment are kept in a sandbox environment, separate from your operating system. Heuristics is about detecting virus-like behavior or attributes rather than looking for a precise virus signature that matches a signature on the virus blacklist.

Best Antivirus Software for Computer and Laptop
Laptops face all the same threats as desktops, from trojans, worms, ransomware, spyware, adware, etc. But in addition to these threats, laptops also face a unique vulnerability to plug-in attacks. Laptops running Windows, macOS, and Linux are all vulnerable to these attacks, which are executed by a cybercriminal compromising an unattended machine through a charger, docking station, or USB port.
To prevent falling victim to these types of attacks, users must install a laptop antivirus bundle that isolates unknown files entering the system. Comodo Antivirus’s containment technology keeps your laptop protected from all types of attacks by automatically isolating all unknown files in a secure virtual environment, where it cannot hard your computer.

Security Software for Android Mobile and Tablet?
Android viruses have been making headlines recently. In September 2019, it was reported that a trojan called “the Joker” had been detected in 24 apps in the Google Play Store and had been downloaded nearly half a million times. There have even been confirmed reports of viruses disguised as fake antivirus apps making their way onto the Google Play Store and receiving over 100,000 downloads. As Android becomes more popular and more versions of the OS appear, Android phones and tablets become more vulnerable to infection, and the importance of protecting your device becomes more essential.
Do I Need Antivirus for Android
The best way to protect your Android device from malware is by installing an antivirus from a trusted provider. Comodo offers a mobile security solution for Android-based mobile devices through Comodo Mobile Security (CMS). CMS protects your Android devices against viruses, unsafe apps, potentially risky settings and even from theft, and is available for free.

Benefits of Using Antivirus for Android Devices
Because Android’s operating system relies on an open source code that allows end users and manufacturers to modify the operating system, Androids phones and tablets are more susceptible to threats than iOS phones and tablets. Therefore, it is essential for android users to download a trusted antivirus app that scans and detects viruses, filters out spam texts and calls, optimizes your system, protects against physical theft of your device, monitors traffic, and advises you on your privacy. Comodo Mobile Security for Android does all this, and is available for free.

Virus Protection for iPhone
Do Apple iPhones Need Antivirus Software
iPhone security has become a hot topic recently, with Google Security researchers alleging that they discovered major iPhone security flaws that allow the devices to be compromised. Apple addressed these concerns in September 2019, stating that the vulnerabilities Google discovered had been exaggerated and were quickly patched once discovered.
Importance of Using Antivirus for iPhone Devices
As most iPhone users know, Apple takes a walled-garden approach to app publishing, allowing only approved apps into the App Store. Because of this, the chances of one of these apps containing malware is very slim. This is a major advantage Apple has over its competitors as far as security is concerned, as evidenced by the issues the Google Play Store has seen with fake, malware-containing apps.
Despite this fact, iPhone users would be wise to add additional security to their phones through a mobile security app. Mobile security apps can ensure greater protection than the iPhone affords on its own, through features like hacked account alerts, identity theft protection, password management, safe browsing, and backups. Comodo Mobile Security for iPhone has all these features and more, and is available for free.

Malware Protection for Mac Devices
Do I Need Antivirus for Mac?
Historically Macs have been considered safer than Windows PCs, and many Mac users have done without an antivirus software. But recent studies have suggested that Mac malware is seeing enormous growth, and although Apple has increased security features and introduced Gatekeeper, which blocks unapproved software from running on your Mac without your agreement, Mac security features have been bypassed. Because of this, it is prudent to install additional protection on your Mac in the form of antivirus software from a trusted provider.
Best Antivirus Software for Mac
Mac users should install an antivirus software that can keep them protected even if there is a vulnerability in their Mac’s built-in security software. The antivirus should provide both continuous protection and on-demand protection against malicious software.
Featuring an on-demand scanner, "always on" real-time protection, and a continuously updated database of known malware, Comodo Antivirus provides superior protection against zero-day malware and other threats that your Mac may face. This is not a stripped-down version of a paid product, it's the real deal. Scan any drive or file. Get in-depth reports on viral activity. Even scan compressed .zip files. Comodo Antivirus for Mac is available for free.

Antivirus for Windows Computer
Windows Defender is improving, but it’s still far from perfect. You should supplement your PC’s defense with a robust antivirus tool
to ensure optimal protection against malware.
Best Antivirus for Windows Devices
The best antivirus for Windows devices should have features that keep your Windows PC protected against holes that Windows Defender leaves. Features like anti-spam, adware prevention, and safe browsing are essential for Windows users.
Do You Need Antivirus for Windows 10?
Windows Defender is a good tool that provides more than baseline protection, but it has been shown by AV Comparatives and other tests to lag behind other antivirus programs when it comes to protecting your PC, and lacks some essential security features, including password managers. To ensure complete protection, relying on Windows Defender is not enough. An additional program, like Comodo Antivirus for Windows 10, is necessary to cover the gaps that Windows Defender leaves.
Antivirus Software for Windows 10
Windows Defender has been shown to lag slightly behind industry leading AV products. An effective antivirus for Windows 10 must be able to supplement Window’s built-in security features and cover any holes they leave. Essential features of an effective windows antivirus that Windows Defender does not provide, include anti-spam, safe browsing, email protection, VPN service, and live support. Comodo Antivirus provides all these features and more for only $29.99/year, making it an ideal antivirus to keep your PC protected.

Microsoft recently warned users that security updates for Windows 7 will come to an end as of January 14, 2020.

How Do Antivirus Programs Detect and Identify A Virus
Modern antiviruses have multiple ways of detecting and identifying a virus. The most basic way to scan every file entering your computer and compare those files against a list of known malware. If the file matches a known malware, it is blocked or deleted.
In addition to this, most antiviruses also use heuristic detection, scanning files and looking for bits of code that’s indicative of a malicious executable. Comodo Antivirus also features Defense + HIPS ( Host Intrusion Prevention System), which sandboxes any unknown files and allows them to run in a restricted environment, where they cannot gain access to the user’s computer if they turn out to be malicious.

It’s simple: prevention-based, Default Deny Protection. It works by only allowing trusted files to run on your system. Files that are not trusted are run inside the new sandbox
The sandbox is a virtual operating environment created within your computer for unknown and untrusted programs. Internet Security automatically runs untrusted programs in the sandbox where they cannot make changes to processes, programs or data on your 'real' system. This protection goes well beyond traditional Antivirus software by ensuring any brand new viruses are completely isolated and cannot cause damage.
Yes. Applications in the sandbox are run under a carefully selected set of privileges and will write to a virtual file system and registry instead of the real system. This means untrusted (but harmless) applications have the freedom to operate as usual while malicious programs are prevented from accessing or infecting your computer. This provides smoothest and most secure user experience possible.
No — the sandbox is the first part of a trust decision engine. After an unknown application has been placed in the sandbox, Internet Security will also automatically queue it for submission to Comodo labs where it will be analyzed by our technicians. If it is found to be harmless then it will be added to the global safe list that will be downloaded by all Internet Security users in the next round of updates. Once it is added to the safe list, the application will no longer be run in the sandbox by Internet Security. If it is found to be malicious then it will be added to Comodo's list of malware signatures and will be deleted after the next round of updates.
Yes. However, enterprises looking to implement Internet Security on large networks of workstations would benefit from the centralized management capabilities of Comodo Advanced Endpoint Security.
Yes — you are given the option to install exactly the components you want during setup.

Secure Shopping
Comodo Secure Shopping is a major new feature in CIS which provides unbeatable security for online banking and shopping sessions. When using Secure Shopping, websites will open inside a security-hardened virtual environment which is isolated from the rest of your computer. This creates a threat resistant tunnel between you and your target website which cannot be monitored or attacked by any other processes running on your computer.
- Hides sensitive online data from other processes on your PC
- Prevents keyloggers from recording your keystrokes
- Warns you if there is a remote connection to your computer
- Stops hackers and malware taking screenshots of your session
- Detects fake SSL certificates to stop man-in-the-middle attacks
But Secure Shopping isn't just for the internet! You can run any application which handles sensitive information inside the secure environment. Examples include:
- Email applications like Outlook and Thunderbird
- Accounting software like Sage
- Password managers
- Spreadsheet software like Excel
- FTP and VPN clients
- Instant messaging and chat applications
- File sharing clients like Drop Box
Applications inside the secure environment are totally sealed-off from other processes on your computer - meaning there is no way that malware can gain access to your data.
The technology behind Comodo Secure Shopping is already being used by major point-of-sale and money-wiring organizations to secure sensitive customer transactions. With CIS, Comodo brings this same level of security to your home. If you need a truly secure place to work and go online, then use Comodo Secure Shopping.

Unblock Applications
Have you ever tried to run a program only to find your security software is blocking it - then can't figure out what you need to do to get it running? Is it the firewall, the behavior blocker, the sandbox or the antivirus which is stopping it? Comodo's new unblock applications feature allows you to release applications with a single click from whichever security component has blocked them.
