🥇1. Norton — Best Antivirus Protection Against Ransomware

🥇1. Norton — Best Antivirus Protection Against Ransomware

Norton is my top choice for safeguarding your Dropbox account from ransomware. It provides excellent malware protection, intuitive apps, and a wide range of internet security tools.

I’m a fan of Norton’s anti-malware engine. It’s a powerful tool that uses machine learning, heuristic analysis, and a large malware directory to detect everything from simple viruses to advanced malware like ransomware. To test the anti-malware engine, I hid a database of nearly 1,000 malware files of my system, including viruses, exploits, worms, trojans, backdoors, zero-day attacks, spyware, and PUPs (potentially unwanted programs) — Norton found every single one of these files when I ran a full system scan.

Norton’s real-time protection is also very effective. Once I was done testing the full malware scan, I turned on the real-time protection and tried to download the same malware files, but Norton blocked all my attempts.

Norton 360 comes bundled with an array of impressive features, including:

  • A secure firewall.
  • Phishing protection.
  • Ransomware protection.
  • Dark web monitoring.
  • Cloud storage.
  • VPN with unlimited data.
  • And more…

Norton’s ransomware protection tool, Data Protector, is really impressive — it prevents ransomware from encrypting your files and folders. When I tried downloading a ransomware simulator containing 25 different ransomware attacks, it blocked the download immediately. Even when I whitelisted the ransomware simulator on my system, Norton’s Data Protector still blocked a good number of the ransomware attacks.

Another one of Norton’s tools that I really like is the password manager. Norton’s password manager provides all the basic password management features you need, such as 256-bit AES encryption, a password generator, auto-save and auto-fill, and password vault auditing. While it’s not as comprehensive as standalone password managers like 1Password, it’s still secure enough to generate and store strong passwords for accounts such as Dropbox.

Norton’s best value plan, 360 Deluxe, offers great features for $49.99 / year*, including excellent malware detection, real-time protection, a password manager, a firewall, 50 GB of secure cloud storage, unlimited VPN access, and dark web monitoring. Plus, it comes with a 60-day money-back guarantee, giving you plenty of time to try it out risk-free.

🥈2. Bitdefender — Excellent Antivirus With Advanced Malware Detection

🥈2. Bitdefender — Excellent Antivirus With Advanced Malware Detection

Bitdefender is one of the top antiviruses of 2023. It provides a lightweight and cloud-based antivirus engine that uses a huge malware directory and machine learning to detect all types of malware, including ransomware. Due to its cloud-based nature, Bitdefender’s anti-malware engine doesn’t take up much CPU or disk space when scanning your device.

The malware scanner is one of the best on the market and is comparable to competitors like Norton. I tested it with the same malware database I used in testing Norton, and Bitdender caught all the malware samples on my device.

Some key features that set Bitdefender apart include:

  • Real-time protection.
  • Web protection.
  • System optimization.
  • Identity theft protection.
  • VPN (200 MB/daily data on most plans).
  • Ransomware protection.
  • And more…

Like Norton, Bitdefender offers powerful ransomware protection. Bitdefender’s Ransomware Remediation tool prevents your files from getting encrypted and restores any files encrypted by ransomware. In my tests, Ransomware Remediation restored the majority of the files I infected with ransomware, which is pretty impressive.

Bitdefender also offers solid identity theft protections that can track as many as 100 pieces of personally identifying information (PII), including phone numbers, addresses, email addresses, social security numbers, and more. I also like that it provides up to $50K in ransomware insurance, so if you ever experience a ransomware attack, Bitdefender’s got you covered. My only issue with Bitdefender’s identity protection is that it’s only available to US users and only as a standalone purchase.

My favorite Bitdefender plan is Total Security ($49.99 / year)  — it provides multi-layer ransomware protection, real-time malware protection, web protection, a firewall, and system optimization tools for up to 5 Windows, Android, macOS, and iOS devices. However, if you want a plan that provides a VPN with unlimited data, I recommend Premium Security, which covers 10 devices and goes for $69.99 / year. All plans come with a 30-day money-back guarantee.

🥉3. TotalAV — Intuitive Antivirus With a Powerful Malware Engine

🥉3. TotalAV — Intuitive Antivirus With a Powerful Malware Engine

TotalAV offers a very simple and user-friendly interface, making it an ideal choice for less tech-savvy users. It also features a powerful antivirus scanner that uses a large malware directory and heuristic analysis to detect both known and emerging malware such as ransomware, worms, viruses, and more.

TotalAV didn’t perform quite as well as Norton and Bitdefender in my malware detection tests, but it still detected a good number of the test files on my system, scoring an impressive 99.6% malware detection rate.

I also like TotalAV’s ransomware protection. To test it out, I ran a ransomware simulator on my PC — impressively, TotalAV blocked the execution of the malware before it could lock up any of my system files.

Some of TotalAV’s other features include:

  • Anti-phishing protection.
  • VPN (virtual private network).
  • Password manager.
  • System optimization tools.
  • Data breach monitoring.
  • Identity theft monitoring (US only).
  • And more…

A standout feature is TotalAV’s performance optimizer, which proved to be more effective at freeing up computer space than many competitors. It provides a number of tools that can help speed up your system’s performance, including a startup manager, an application uninstaller, a browser cleanup tool, a duplicate file finder, and a junk cleaner that removes junk files — all of which worked as promised.

TotalAV’s password manager also works really well. It has a good password generator, and it keeps your password history, so you can check it if you forgot to save a password. Additionally, it has 2FA, data breach monitoring, a security report, and a cool feature called Secure Me which lets you remotely log out on all devices. The password manager is available as a standalone app or packaged with TotalAV’s most expensive plan — TotalAV Total Security. Norton’s password manager, on the other hand, is included with all of Norton’s plans.

If you already have a standalone password manager, you can opt for TotalAV Internet Security — it costs $39.00 / year and provides a malware scanner, real-time protection, web protection, system tune-up tools, and an unlimited VPN for up to 5 devices. All purchases come with a 30-day money-back guarantee.

4. McAfee — Good Option For Online Security

4. McAfee — Good Option For Online Security

McAfee stands out with its impressive range of internet security features. Like Norton and Bitdefender, it scored a perfect 100% detection rate against all of my malware samples (including ransomware) during my tests. However, I did experience a bit of slowdown during full system scans.

McAfee also provides:

  • Anti-phishing protection.
  • A firewall.
  • A password manager.
  • VPN.
  • Identity theft monitoring.
  • And more…

McAfee has an excellent anti-phishing tool, WebAdvisor, that protects you from dangerous sites that may unleash ransomware attacks upon visitation. I tested WebAdvisor against 100s of phishing websites, and it blocked every single one, including the ones built-in protections from Chrome and Firefox failed to detect.

I’m a fan of McAfee’s firewall, too — it’s powerful, intuitive, highly customizable, and more accurate and effective than the built-in firewalls provided by Windows and macOS. I tested it against a variety of threats, including exploit attacks, network intrusions, and malware programs attempting to communicate with remote servers — McAfee detected every single one of these threats.

McAfee’s Total Protection Premium plan offers the best value. For $49.99 / year, it provides coverage for an unlimited number of devices and includes an antivirus scanner, anti-phishing protection, a firewall, and identity monitoring.

5. Intego — Best Antivirus for Mac (With Great Optimization Tools)

5. Intego — Best Antivirus for Mac (With Great Optimization Tools)

Intego is the best antivirus solution for macOS in 2023. It’s equipped with an excellent malware scanner, an intuitive dashboard, and great optimization tools for Mac devices. Most competitors, including Norton and Bitdefender, provide more features for Windows than for MacOS, so I think it’s great that Intego is completely focused on macOS.

I’m a fan of Intego’s antivirus engine, VirusBarrier. During my tests, it detected all of the malware samples I hid on my MacBook. Its real-time protection is also very effective, as it blocked all the ransomware simulations I launched against my Mac. What’s more, VirusBarrier lets you scan any connected external drives or iOS devices, so you can always keep your iPhone and iPad safe from ransomware and other malware too.

Intego also includes:

  • Real-time malware protection.
  • Advanced backup options.
  • Mac optimization and cleaning tools.
  • Network security options.
  • And more…

The data backup tool provided by Intego is a step ahead of Mac’s built-in version. It offers a high degree of customization, allowing you to back up specific files or folders to an internal or external hard drive. So if your Dropbox account is ever encrypted by ransomware, you can easily access your data from your hard drive.

The scheduling feature is handy as well — I was able to schedule frequent backups for crucial documents and weekly backups for less important files. There’s also a Bootable Backup option that allows you to back up your entire system with your current Mac OS X version.

One criticism I have of Intego is its lack of a single interface. Unlike Norton and McAfee, which provide a unified user interface for accessing most features, Intego requires you to download an individual app for each feature, which can lead to a bit of confusion until you become accustomed to the system.

Intego offers multiple plans that cater to different needs, starting at $1.67 / month. However, I recommend the Mac Premium Bundle X9 plan, which costs $34.99 / year and provides a malware scanner, effective system optimizer, a firewall, and backup tools. This plan also comes with a 14-day free trial, but if you feel that’s not enough time for you to test it out, you can still try it out risk-free with Intego’s 30-day money-back guarantee.

What To Do if Your Dropbox Account Is Affected by Ransomware

1. Disconnect from the internet. As soon as you notice ransomware infection, disconnect your device from the Dropbox network. This helps prevent the ransomware from spreading to other connected devices or communicating with its control servers.

2. Quarantine infected files. Identify the files encrypted by ransomware. Segregate them to a separate folder or remove them from your synced Dropbox folder to prevent the compromised files from affecting your other devices.

3. Report the incident. Notify Dropbox support about the ransomware attack. They can provide guidance and assist in your recovery process.

4. Remove the ransomware. Employ a trusted antivirus or anti-malware software like Norton to scan and eliminate the ransomware from your device. Ensure your antivirus software is updated before you conduct the scan.

5. Restore unaffected files. If you’ve maintained a backup, restore the clean versions from your backup source, replacing the encrypted files. Use an antivirus to verify that the backup files are malware-free before restoring them.

6. Change your Dropbox password. After securing your device, change your Dropbox password. Opt for a unique, robust password, preferably generated by a reliable password manager like 1Password.

7. Enable two-factor authentication (2FA). 2FA is a significant enhancement to your Dropbox security, requiring a second form of verification during login. If it’s not already enabled, activate 2FA.

8. Restore files from Dropbox. Dropbox’s version history feature allows you to restore previous versions of the encrypted files. Navigate to the impacted files in your Dropbox account and use this feature.

9. Educate yourself and take all available security measures. Learn from this incident. Understand how the ransomware infiltrated your system and take steps to prevent future attacks. Follow all recommended security measures — keep your software updated, browse safely, and reinforce your overall cybersecurity approach.


How Can Ransomware & Other Malware Affect Cloud Storage?

Cloud storage, despite being convenient and widely-used, is not immune to cyber threats such as ransomware and other types of malware. Ransomware, in particular, is a type of malicious software designed to block access to a computer system or files until a ransom is paid. This form of malware can infiltrate cloud storage, encrypting your data and making it inaccessible.

Another harmful variant is spyware, which operates by infiltrating your device without your consent, collecting sensitive data and uploading it to the cloud without your knowledge. Remote Access Trojans (RATs) provide cybercriminals with full control over your device, allowing them to manipulate your data, including what you have stored in the cloud.

Keyloggers, another nefarious type of malware, record your keystrokes, thus potentially capturing your cloud storage login credentials. This information can then be exploited to access and manipulate your cloud data.

Furthermore, phishing attacks can lead to cloud storage compromise. These typically involve duplicitous emails or messages disguised as being from legitimate sources, which try to coax you into providing your login credentials or clicking on malicious links.

Overall, your cloud storage can be a target for multiple forms of malware — which reinforces how important it is to take robust cybersecurity measures.


Does Dropbox Protect Your Files From Ransomware?

Dropbox employs several measures to protect your files from ransomware and other forms of cyber threat. At its core, Dropbox uses 256-bit AES encryption for files at rest (data already on the server) and Secure Sockets Layer (SSL)/Transport Layer Security (TLS) for data in transit (data moving across the network, between Dropbox apps and servers). This provides a solid security foundation against ransomware attacks.

A particularly useful feature is Dropbox’s “version history”. This allows users to restore files to their previous versions before they were infected or encrypted by ransomware, effectively mitigating the potential damage.

Furthermore, Dropbox offers selective sync options. This feature lets you select which files and folders to sync, providing an additional layer of control and safety.

Finally, Dropbox provides security features such as ransomware detection and security alerts that alert you in the case of any suspicious activity.

However, it’s important to note that these protective measures don’t replace a robust antivirus. Despite Dropbox’s best efforts, it’s not specifically designed to combat malware. Therefore, it’s essential to use a powerful antivirus program in conjunction with Dropbox’s security features for comprehensive protection against ransomware.


Is It Possible to Restore Ransomware-Encrypted Files on Dropbox?

Yes, it is possible to restore files that have been encrypted by ransomware on Dropbox, thanks to a feature called “version history.” This powerful feature enables users to revert files back to a previous state, essentially undoing the encryption caused by ransomware.

Here’s how it works: Dropbox maintains a record of each change made to your files for a specific period (30 days for free accounts and 180 days for premium accounts). This means that if your files are encrypted by ransomware, you can access the version history and revert to an unaffected version of the file.

To do this, log into your Dropbox account, hover over the file or folder you’d like to view the version history of, click the three horizontal dots, hover over “activity”, and click on version history. You will see a list of all previous versions of the file with date and time stamps. Choose the version before the ransomware encryption occurred and click “Restore.” This action replaces the encrypted file with the chosen version.

However, this feature is most effective when you quickly identify a ransomware attack. If the attack goes unnoticed beyond the version history retention period, recovery becomes more complex.


Is Dropbox Secure Enough in 2023?

Dropbox has been continually improving its security measures to protect user data. The platform uses 256-bit AES encryption for files at rest and secures data in transit with SSL/TLS encryption. It also has two-factor authentication (2FA), providing an extra layer of security against unauthorized access.

In addition, Dropbox offers “version history” and “selective sync” features, which can help recover files encrypted by ransomware and control which files and folders to sync, respectively. However, these measures are more about recovery and control rather than proactive protection against malware.

Dropbox had a significant security breach in 2012, where email addresses and encrypted passwords were stolen. The cloud storage provider also experienced another breach in 2022, but this time around, no Dropbox account, passwords or payment information was accessed. Since then, the company has significantly ramped up its security measures and there have been no reported major breaches.

While Dropbox offers solid security features, it’s not entirely immune to cyber threats. It’s best to use it in conjunction with a robust antivirus program for comprehensive protection. Dropbox can safeguard your files to a large extent, but it cannot detect or remove malware like a dedicated antivirus can.


Frequently Asked Questions

How secure is Dropbox?

Dropbox is generally secure, employing a range of security measures to protect your files. It uses AES 256-bit encryption for files at rest, and Secure Sockets Layer (SSL)/Transport Layer Security (TLS) for data in transit. These encryption standards create a robust barrier against unauthorized access. Furthermore, Dropbox offers two-factor authentication (2FA), adding an extra layer of security to user accounts.

But while these measures enhance Dropbox’s security, they are not a replacement for a comprehensive antivirus program like Norton, which can detect and remove various threats like ransomware and other malware.

Is Dropbox safe from ransomware?

Dropbox provides a ransomware detection feature that helps to prevent malicious ransomware attacks from spreading. It also sends you security alerts whenever it notices any suspicious behavior or activity in your account. What’s more, it has some measures that can mitigate the effects of a ransomware attack, such as a “version history”, which allows you to revert your files to previous versions. This could be used to restore files if they were encrypted by ransomware.

Nonetheless, the first line of defense against ransomware should always be a quality antivirus solution with real-time ransomware protection.

Can Dropbox spread malware?

Dropbox, as a platform, does not spread malware. However, if a user unknowingly uploads a file infected with malware to Dropbox, other users who download that file could have their devices infected. Therefore, it’s crucial to maintain good cybersecurity practices, such as scanning files with a reliable antivirus program before uploading or downloading them from Dropbox, to prevent such occurrences.

Does Dropbox encrypt your files?

Yes, Dropbox employs strong encryption measures to protect your data. It uses 256-bit AES encryption for files at rest on its servers. This level of encryption is incredibly secure and unhackable. Furthermore, for data in transit, such as when you’re uploading or downloading files, Dropbox uses SSL/TLS encryption. This creates a secure channel between your device and Dropbox servers, making it very difficult for anyone to intercept and read your data.
