Is anti-malware software worth it? 
I

After an enlightening chat with Tim Rains earlier this week, a question jumped to mind – are anti-malware solutions doing their job? Tim, of course, was quick to make the positive case. But _secpro doesn’t thrive on positive cases – we want to know what happens if we abandon anti-malware software! 

The most obvious answer is: you’re going to get some virues. We’re aware of that. But we’ve diving in a bit deeper – should a competent security team rely on an anti-malware solution to save them from the adversary? The answer to that question is a little more complicated… 

Should I use anti-malware software? 

Yes, it is highly recommended to use anti-malware software to protect your devices and data from malicious attacks. Anti-malware software can help detect and prevent the installation of malware, such as viruses, Trojans, spyware, and ransomware, on your devices. It can also scan your system for any existing malware and remove it if found. By using anti-malware software, you can reduce the risk of your devices and data being compromised, and ensure that your online activities are safe and secure. 

Keep in mind, however, that no single solution can provide 100% protection, and it’s important to also practice safe computing habits, such as keeping your operating system and software up-to-date, avoiding suspicious email attachments or links, and using strong passwords. 

Why do some cybersecurity professionals say we shouldn’t use anti-malware solutions? 

While anti-malware software can be an important part of a comprehensive cybersecurity strategy, there are some professionals who believe that relying solely on anti-malware solutions is not enough to protect against today’s evolving threat landscape. Here are a few reasons why: 

  • False Positives: Anti-malware software can sometimes mistakenly identify a benign file as malware, which is known as a false positive. This can result in important files being deleted or quarantined, which can cause serious problems. 
  • Limitations: Anti-malware software is only able to detect malware that it has been specifically designed to detect. New and evolving malware can often bypass anti-malware software, leaving your devices and data vulnerable. 
  • User Error: Anti-malware software can only protect you if it is properly configured and updated. If a user does not regularly update their anti-malware software or engage in risky online behavior, such as downloading files from untrusted sources, their devices may still be vulnerable to attack. 

Therefore, some cybersecurity professionals believe that a multi-layered approach, which includes anti-malware software as one component, is a more effective approach to cybersecurity. This might include regular backups, firewalls, secure passwords, and user education, in addition to anti-malware software. 

To what extent are anti-malware solutions limited? 

As we’ve already covered, there are limitations to anti-malware. And, even more obviously, the anti-malware sales teams aren’t going to be sharing that information with you before you purchase them. But there are certain limitations to this type of software that you must be aware of before you implement it. Anti-malware solutions are limited in several ways: 

  • Detection rate: Anti-malware solutions can only detect malware that they have been specifically programmed to identify. This means that new, unknown, or sophisticated malware may not be detected. 
  • Evasion techniques: Malware authors are constantly developing new techniques to evade detection by anti-malware software. For example, malware may use encrypted or packed code, which makes it harder for anti-malware software to identify and neutralize it. 
  • False negatives: Anti-malware solutions can sometimes fail to detect malware that is present on a system. This is known as a false negative, and it can occur if the malware is new or has been specifically designed to evade detection. 
  • Resource utilization: Anti-malware software can consume a significant amount of system resources, such as memory and processing power, which can slow down your device and impact performance. 
  • User error: Anti-malware software can only protect you if it is properly configured and updated. If a user does not regularly update their anti-malware software or engage in risky online behavior, such as downloading files from untrusted sources, their devices may still be vulnerable to attack. 

Despite these limitations, anti-malware software can still provide an important layer of protection against malware and other threats, and it is generally recommended to have it as part of a comprehensive security strategy. 

What would happen if I stopped using anti-malware software? 

If you stop using anti-malware software, your devices and data will be more vulnerable to malware and other cyber threats. This can result in a variety of consequences, including: 

  • Infections: Without anti-malware software to protect your devices, you may be more likely to become infected with malware, such as viruses, Trojans, spyware, and ransomware. This can lead to data theft, data loss, and a range of other problems. 
  • Performance issues: Malware can cause slowdowns, crashes, and other performance issues on your devices, making it difficult to use them effectively. 
  • Data loss: Malware can delete or encrypt your data, making it unavailable to you. In some cases, you may need to pay a ransom to get your data back. 
  • Privacy concerns: Malware can steal sensitive information, such as login credentials, financial information, and personal information, and send it to attackers. This can result in identity theft, financial losses, and other privacy violations. 
  • Network compromise: If you have an infected device on your network, it can spread malware to other devices, compromising the entire network. This can result in a domino effect, where multiple devices are infected and data is lost. 

Therefore, it is important to continue using anti-malware software to help protect your devices and data from malicious attacks. Keep in mind, however, that anti-malware software is not a panacea, and it is important to also practice safe computing habits, such as keeping your operating system and software up-to-date, avoiding suspicious email attachments or links, and using strong passwords. 

Who are the most notable people saying we shouldn’t use anti-malware? 

While the majority of the cybersecurity community recommends using anti-malware software as part of a comprehensive security strategy, there are a few notable individuals who have argued against relying solely on anti-malware solutions. 

  • Dave Aitel: A former NSA researcher and the CEO of Immunity, Inc., Aitel has argued that anti-malware software can provide a false sense of security and that relying solely on such software can be dangerous. 
  • Marcus Ranum: A security engineer and the founder of Tenable Network Security, Ranum has criticized the anti-malware industry for its focus on detection rather than prevention and has argued that relying solely on anti-malware software is not enough to protect against cyber threats. 
  • Bruce Schneier: A security technologist and the CEO of Counterpane Internet Security, Schneier has argued that anti-malware software can be effective against certain types of malware, but that it is not a complete solution and that other security measures, such as firewalls, intrusion detection systems, and user education, are also important. 

It is important to note that these individuals are not necessarily advocating against using anti-malware software altogether, but rather against relying solely on such software to protect against cyber threats. They generally recommend using anti-malware software in combination with other security measures to provide comprehensive protection against cyber attacks.
