Modern day antivirus software fulfils a variety of different functions across several platforms, including desktops and laptops, smartphones, tablets and any other Internet-connected devices. Robust, well-managed anti-malware software represents the first line of defense in the global fight against cybercrime and the proliferation of malicious software designed to extract money and sensitive data from unsuspecting users.
How Anti-Malware Software Works
Anti-malware software engages with multiple techniques to differentiate malicious files from legitimate data within a computer system.
Signature detection
Signature detection is the primary method cybersecurity companies use to identify malicious code. Once discovered and analyzed, a virus’s ‘signature’ (unique code relating specifically to that virus) is added to a huge database of similar viruses. Signature databases are updated daily, as and when new viruses appear all over the world.
Rootkit detection
A ‘rootkit’ is the method used by a virus to control the underlying operating system of the computer that it has infected. Anti-malware platforms contain rootkit detectors to eliminated the problem at its source and prevent a virus from gaining administrative control over the host device.
Consequences of Not Using Anti-Malware Software
For businesses and individuals alike, the consequences of failing to operate with a modern, feature-rich anti-malware platform are a loss of business continuity, theft of personal information and in extreme cases, monetary loss.
You may think that it will never happen to you, but history has shown us that virus attacks pay no heed to organizational size, revenue, employee number or geographical location. Ultimately, business-disrupting attacks are on the rise.
Insurance companies often require a comprehensive analysis of cybersecurity measures before paying out on business interruption plans. If your organization is found to be lacking in this regard, you could face a cancellation of your policy and significant financial damage in the event of an attack.
Key Features
Real-time protection
Most modern antivirus platforms feature real-time protection tools that scan incoming file attachments, opened files and executable programs for instances of malicious code. They alert the user accordingly.
Scheduled scanning
Antivirus scans can be scheduled at daily, weekly or monthly intervals to cater to the unique requirements of each organization and user type.
Automatic updates
Virus definitions are downloaded from a global definitions database as and when they are released, populated by the collective research of prominent cybersecurity professionals all over the world.
‘Sandboxing’
Sandboxing involves an anti-malware platform running a virtualized instance of an operating system (e.g. Windows) to ascertain the threat level of a suspicious object or program. The virtual environment is separate from the host OS and totally isolated from a company’s business network.
Managed vs. Unmanaged Anti-Malware Platforms
Antivirus software can broadly be classified into two main formats – managed and unmanaged.
Managed antivirus platforms
Managed antivirus platforms are integral to any PCI or HIPAA compliance strategies. Managed anti-malware solutions offer a centralized hub for administrative staff to perform automatic updates, install and uninstall virus software, produce reports on a per-user basis and populate a visual dashboard of anti-malware adherence across multiple sites and platforms. These days, it’s pretty much inexcusable for organizations to operate with anything other than a managed anti-malware platform, even for small organizations of 5-10 users.
Unmanaged antivirus platforms
Unmanaged platforms eschew the need for centralized management and incorporate individual installs of software that require standalone updates and user management. Unmanaged antivirus solutions are ideal for single users, easier to install and don’t require the same ongoing levels of expertise to manage them on a day to day basis. However, they are inherently less secure than their managed counterparts and are usually the choice for companies who are looking to cut corners, rather than to pay adequate attention to their cybersecurity obligations.
The Top Anti-Malware Platforms
Sophos
Best for: SMEs
Sophos are a prominent cybersecurity solutions provider who offer an extensive range of anti-malware and virus detection tools across an exclusively cloud-based and cloud-managed platform. Their ‘Intercept X’ anti-malware tool is specifically tailored to meet the antivirus requirements of US and European SMEs. Intercept X integrates with many of Sophos’ other endpoint security products and email management tools, offering a powerful one stop shop for all your cybersecurity needs.
Malwarebytes
Best for: Basic option
Malwarebytes grew from humble beginnings in a computer repair shop in Chicago to become the go-to anti-malware option for hundreds of thousands of users worldwide. The platform is renowned for its feature-rich option that provides personal users with most (but not all) of the functionality they need in a modern antivirus platform. The software also contains Adwcleaner – a browser based anti-malware tool that prevents programs from amending your default search engine or adding unwanted toolbars and menu items.
Webroot SecureAnywhere
Best for: Blocking malicious programs
Webroot consistently scores top of the tree on malware blocking tests and system resource usage. Webroot’s SecureAnywhere uses sandbox-based technology to virtualize the operating system and open a suspicious file within a bubble environment, mitigating the real-time risk of executing malicious code.
Norton Antivirus
Best for: Features
Norton Antivirus is highly popular anti-malware platform distributed by the cybersecurity multinational NortonLifeLock (formerly the Symantec Corporation). Norton AV has a reputation for its enormous array of features, industry-leading technical support, fast and efficient real-time protection techniques and cross-compatibility with other cybersecurity platforms.
How to Choose the Right Platform
Anti-malware services have become a catch-all term for any antivirus program that seeks to identify and eliminate malicious software at source, but in reality, the main distinction to be made is between a business-oriented, commercial platform, and an unmanaged instance of domestic antivirus software.
