Occasionally, you might come across an article where the author suggests that antivirus (AV) software is no longer necessary either because it is simply ineffective or because operating systems have built-in antivirus capabilities that are sufficient to ward off cyber attacks.
Is it mandatory to use antivirus software? No, of course not. You can put your computers and data at risk any time you want. Just be prepared to suffer the consequences. A better question would be are antivirus programs worth it? Or is antivirus necessary? The answer? Absolutely. An antivirus is both necessary and worth it. Here are six important reasons why:
-
Virus databases
While having built-in AV software is patently better than having no AV software at all, built-in antivirus software does have its weaknesses. One of them is its virus signature database. The virus signature database is a database of known virus signatures, and signature-based detection, one of the earliest and still one of the most widely used methods of virus detection rely on this database to detect viruses.
The AV software compares the virus signatures in the database to the signatures of files on a computer. If a match is found, it means a virus has been detected, so the antivirus software will proceed to quarantine and remove the infected file. However, some built-in antivirus software doesn’t update their signature database frequently enough to include the most recently discovered virus signatures.
When that happens, the AV is not able to detect newly discovered viruses, which means those viruses will be able to pass through the AV defense undetected. In contrast, third-party antivirus solutions use virus signature databases that are continuously updated so they always have access to the most recently detected virus signatures for comparison.

Zero-day threats
There are approximately 350,000 new malware variants released onto the threatscape every day. When you don’t use antivirus software you expose your computers and your data to all those variants. Even built-in solutions, while better than they used to be, are not effective at defending against zero-day or unknown and emerging threats.
To successfully defend your computers and your data against zero-day threats, you need third-party antivirus software. In addition to signature-based detection, third-party software also has sophisticated detection capabilities such as behavior-based and heuristics-based detection that are needed for detecting and protecting you from new and emerging malware, not just known malware.
-
A wider range
With a third-party antivirus, you can also expect a wider range of cybersecurity features as compared to a built-in antivirus. For example, the more powerful antivirus solutions also offer anti-tracking, safe browsing, unwanted software, anti-ransomware, and camera and microphone protection. Moreover, third-party antivirus solutions are far more effective than built-in solutions against dangerous attack avenues such as phishing, adware, spyware, malicious URLs, etc.
-
Excellent customer support
Third-party antivirus software is unquestionably your ally; without it, you won’t have protection against viruses, phishing, malicious downloads, ransomware, and other dangerous malware. Neither will you have the technical support you need if any cybersecurity questions or issues arise. With a third-party antivirus, on the other hand, you get qualified technical support to help you when cybersecurity concerns do arise – a friendly anchor on a very dangerous threat surface. Most third-party antivirus solutions offer email, phone, and chat support channels, with better solutions even offering 24/7, live support.
-
Endpoint protection
Endpoint protection is especially critical to businesses because it provides antivirus and anti-malware protection for all endpoints. It also allows businesses to monitor and control the level of protection of all their devices from a single, easy-to-use interface and ensures that software on all systems is regularly and uniformly updated. Updates, by the way, are critical to cybersecurity. They are what patch those pesky security holes in your software that if left unpatched leave your computers and your data vulnerable to attack. These security holes are a favorite attack vector for hackers because they require a minimum of end-user involvement to be successful. If you don’t have an endpoint antivirus solution, you have to manually update your computer software every time a new patch is released. The best way to secure a business’ privacy posture, therefore, is with an endpoint solution that delivers comprehensive threat protection to all endpoints and has a security control dashboard for total transparency of endpoint security statuses.
-
Simply not worth the risk
It all boils down to risk. Not having dedicated antivirus protection leaves your computers and your data vulnerable and exposed to cyber-attacks. Successful cyber-attacks can be monumentally destructive and damaging, and the cost of treating your computer in terms of money, time, system performance and data, is far more than you’ll ever spend on protecting your system with an antivirus solution. It’s simply not worth the risk to not have antivirus software.
