Can antivirus stop hackers? What you need to know

The short answer is yes, an antivirus is a robust hacking protection software. While free antiviruses typically block fewer hacks, paid services stop 95-99% of malicious attempts. Which one you choose matters most, as antiviruses have significantly different anti-malware and scam protection capabilities.

In 2024, the US residents lost over $16 billion to cybercrime, including malware, ransomware, and phishing, alongside investment and identity theft scams. An antivirus is widely considered a must-have for malware protection.

Because most modern devices have built-in protection, like Microsoft Defender, some consider another antivirus redundant. In reality, top antivirus apps help prevent cyber attacks, and often pack additional benefits, like a password manager and a VPN.

A good antivirus catches malware like trojans, keyloggers, and ransomware, one of the biggest cyber threats against businesses. As of now, it is an irreplaceable cybersecurity tool. In this article, I will outline its capabilities and limits to help you remain safe online.

Understanding the difference between malware and hacking

Although malware and hacking often go hand-in-hand, they should not be used synonymously. Hacking does not necessarily involve malware, as hackers can simply trick people into giving out personal information, like passwords or credit card details.

However, malicious software is still extremely dangerous, as it provides hackers with tools to cause enormous damage. The Colonial Pipeline hack in 2021 is a perfect example, where hackers used a stolen password to cause a $4.4 million ransom attack.

Hacking always involves a human actor or a group and exploits various vulnerabilities, including simple human error. Meanwhile, malware is an automated software that can execute without human intervention. Malware can be a straightforward spyware, like keyloggers, or an extremely complex chunk of code, like the Stuxnet worm.

For casual internet users, most will encounter both human hackers and computer viruses. An example being: a hacker can send a phishing email pretending to be a bank official or a technical support agent. It has a PDF file attached, infected with infostealer malware. It then automatically collects sensitive data and sends it to criminals for further scams, like credit fraud.

How antivirus actually blocks hacking attempts

Antivirus programs are constantly evolving to protect against evolving threats. They integrate AI-powered tools to detect and neutralize more online threats faster, like behavioral analysis. Simultaneously, they release new antivirus features for security against AI-driven attacks, particularly common in evolving phishing scams.

AI-powered behavioral analysis strengthens real-time protection. It lets antivirus software neutralize unknown threats on the spot. Even if hackers use brand-new malware to infect the device with what looks like legitimate software, behavioral analysis identifies malware by analyzing its actions.

For example, if you download a simple PDF reader that suddenly starts encrypting files, an antivirus software marks it as ransomware, stops its execution, and rolls back all malicious changes. If a person receives a phishing email, an antivirus checks for scam patterns, like a fraudulent sender's address and links pointing to scammy websites.

Fully-developed antivirus software often includes a firewall in its cybersecurity benefits. A firewall works at a network level, checking incoming and outgoing traffic for malicious elements. Imagine it as a concert security guard who controls who can get in and go out.

Traditionally, antivirus software excels at locating malware that already infects the device, and a firewall secures the outside perimeter. In 2026, you will often encounter both in the same subscription to ensure a defense-in-depth strategy.

This way, users can install a single antivirus, but protect multiple device vulnerabilities. It is especially important nowadays, when even low-experience backers can use AI to optimize scams. Malware is being sold online on black markets for low prices, so antiviruses ensure protection against an increasing variety of threats.

Why Webroot is the smart choice for hacking prevention

Firstly, Webroot relies on cloud-based scanning. Instead of simply comparing suspicious elements to known malware blacklists, Webroot quarantines in the cloud. It analyzes new files in real-time and compares their behavior on a global computer network. If Webroot detects a new file that was marked as malicious elsewhere, it prevents its execution on your device immediately. It also journals its behavior from the start and rolls back any changes if the file proves to be malicious.

Additionally, Webroot incorporates Privacy Shield into all plans, which was before a stand-alone service. If a hacker infects your device with a keylogger, Privacy Shield encrypts your button clicks so that passwords you type are indecipherable. If malware is designed to take screenshots, this tool blocks them and prevents secured apps from sending data online.

It is different from typical antivirus apps that aim to locate and remove the threat first. Webroot Privacy Shield focuses on the malicious software goals, rendering it useless even if malware manages to slip through antivirus and firewall detection.

Lastly, the cloud-based approach makes this antivirus very lightweight. It doesn't consume limited device resources to analyze thousands of data points, but delegates it to powerful cloud servers. It makes Webroot 6 times faster than the average competitor at scanning your device. Hence, I’d argue it’s a good option for older device safety.

Protecting yourself in the evolving digital world

Cybercrime is evolving, with criminals finding new ways to scam people and exploit unprotected devices every day. According to AV-Test cybersecurity experts, they register 450,000 new malware samples daily. That’s why it’s as important as ever to stay informed and be mindful of the scenarios below in addition to protecting yourself online with antivirus software.

An antivirus does not, directly, protect against social engineering scams. If you share your private information online with a malicious actor willingly, then there's no need to hack your device in the first place. According to the Federal Trade Commission, imposter scams, a part of social engineering, cost consumers $3.5 billion in 2025.

Weak and reused passwords also evade antivirus detection. If you use 'password123' on multiple accounts, a simple brute-force attack can snatch them in under a minute. Instead, you should use a password manager that stores complex passwords in an encrypted vault. Webroot takes care of that by including a password manager in all its plans.

Lastly, make sure all software is updated to the latest version. Although most software updates now happen automatically, you may postpone one while on mobile data or an older operating system. Cybercriminals use tools like Shodan search engine to find unpatched apps and devices that connect to the internet, which puts users at risk if they don't do it on time.

For those who want comprehensive coverage, Webroot Total Protection bundles everything into one package. Beyond antivirus, it includes identity protection, dark web monitoring, cloud backup, and a VPN, covering every touchpoint where modern threats can reach you. As cybercrime grows more sophisticated, relying on a single layer of defense is no longer enough. An all-in-one solution like Webroot Total Protection keeps you protected without having to piece together multiple tools yourself.

Checklist for a hacker-proof setup

Here's how to block hackers in a few steps you can take right now:

1. Install Webroot as your trusted antivirus software.
2. Set up multi-factor authentication to protect your account from brute force attacks.
3. Make sure all of your software is updated to the latest versions.
4. Apply the previous steps to all internet-connected devices.
5. Do not use the same simple password for multiple accounts.
6. Use a VPN while on public Wi-Fi networks (Webroot Secure VPN is a great option!).
7. Be aware of the most popular phishing and social engineering scams.

Conclusion: the evolution of hacking defense

In 2026, cybersecurity is about combining different cybersecurity tools with healthy browsing habits. Education is still your first line of defense, as most online scams still rely on human error.

But without an antivirus, your doors are wide open for a wide range of hacks and scams. Webroot will protect your device from info stealers by encrypting your keyboard clicks. Even if one infects your device, it will be rendered useless.

Its advanced approach of using cloud for malware scanning ensures that threats are detected before they can even reach your device. It also makes Webroot lightweight and resource-friendly. And remember, scammers always look for the easiest profit.

Try to look at it from the hacker’s perspective. If they notice an active firewall or public Wi-Fi protection, it's usually not worth the effort. The cost of entry becomes too high compared to possible profits, and cybercriminals will look for other, less protected devices.
