Does Antivirus Detect and Remove All Malware?

While antivirus software significantly contributes to digital security, it’s essential to recognize that they don’t guarantee complete protection or eliminate every single instance of malware and viruses.

How Does Antivirus Software Work?

Always remember that no antivirus software, whether online or offline, can offer you 100% protection. All antivirus software works based on virus definitions. What are virus definitions? Basically, it’s a type of database that contains information on all dangerous codes, files, and other data, enabling antivirus programs to recognize harmful viruses and malware.

Cybercrime has become a huge industry, constantly attempting to steal users’ data, money, or sometimes both. So, having antivirus software is essential.

Antivirus programs regularly scan your system – files, applications – and if they detect anything malicious, whether it’s malware or a virus, they immediately block it or quarantine it to isolate it from harming your computer. However, it’s not always guaranteed that antivirus software will detect every virus or malware.

Even the most popular and excellent antivirus software like Norton or McAfee doesn’t have a 100% success rate.

Can Antivirus Detect all the Malware?

Now, as I mentioned earlier, antivirus software works based on a database. If a particular virus or malware isn’t listed in that database, it can easily cause harm to your computer, infecting your system. Antivirus companies always strive to update their databases regularly.

However, there are many instances where a new virus emerges, but the database isn’t updated in time. If antivirus companies fail to update their databases, that new virus can easily infect many users.

Moreover, some viruses or malware are designed specifically to evade detection by antivirus programs. These are generally called stealth viruses. They use code modification and encryption techniques to trick standard antivirus scans.

If you genuinely want proper protection, you must always keep your antivirus software updated. Regular updates bring fixes to different flaws, remove bugs, and overall enhance the quality of the product. Certainly, updating the virus definitions is also a crucial part of this process. So, if you don’t update your antivirus software, it’s basically ineffective.


If you prefer third-party antivirus software, always opt for a paid one. You can choose a monthly or yearly subscription. But never rely too much on free antivirus software. If you’re unwilling to spend money on antivirus software, you can use the built-in antivirus programs like Windows Defender or Windows Security. However, note that installing a third-party antivirus might disable these built-in tools.

If you’re willing to spend money, go for a paid antivirus program. But if you’re not keen on spending, there’s no need to install any antivirus program as Windows Defender is more than enough. In my opinion, when it comes to which antivirus is better, Norton and McAfee are still highly rated.

Speaking of security, many antivirus software programs offer additional services beyond basic antivirus protection, such as VPNs, password managers, anti-spam, file shredders, and firewalls. If you require these features, you can look into those antivirus options.

Keep Yourself Safe Online

Now, if I share some tips and tricks you can follow for maximum security, first, consider purchasing a VPN service if you want maximum security. A VPN routes your internet traffic through remote servers, encrypting your data, making it nearly impossible for your ISP, government, or malicious actors to track your online activities, adding another layer of security.

Also, whenever downloading something online, avoid the flashy download buttons. Look for the actual download link or a small, authentic button. Avoid visiting suspicious websites and try avoiding pirated software or apps.


Regarding emails or various chats on platforms like WhatsApp, refrain from clicking on malicious or suspicious links. Don’t fall for scams like “iPhone for 1 Rupee” or “Win 1 Crore in Lottery.”

If your email provider, like Gmail for example, offers a spam filter, it’s better to keep it enabled for added protection.

You can employ link-checking services to scrutinize website URLs and verify their safety. Malicious links are often utilized by cybercriminals to propagate malware or conduct social engineering scams. Therefore, before clicking on any link received, ensure its authenticity by running it through a checker.

It’s crucial to safeguard all your devices with passwords or biometric scanning. Although many malware instances occur remotely, there are cases of manual infection requiring direct access to the target device. To minimize this risk, ensure your devices are locked, allowing only authorized access, thus enhancing your security.

Antivirus Software is Crucial for Maximum Safety

While antivirus programs aren’t flawless in providing complete protection, they remain vital for maintaining digital security. If you’re relying on a reputable and trusted antivirus provider, continue using it as it actively safeguards your device against malware and viruses. It’s not flawless tech, but it’s definitely a valuable tool worth keeping.
