5 Best Free Online Virus Scanners & Removers for 2021

I hate to break it to you, but there are virtually no internet virus scanners. The majority of them are simply trial versions of paid software, many of them do nothing, and some of them are phishing sites attempting to steal your data or get you to download malware. Fortunately, there are a few online cybersecurity programs, as well as a few one-time downloads, that can truly assist you in cleaning out your computer.

  1. On the internet, there are two types of tools:
  2. Vulnerability scanners that can ensure the native protections in your program are up to date.
  3. Free virus scanners that can scan your entire computer for infection can be downloaded for free.

Personally, I wouldn’t switch on my computer for a second without first installing high-quality antivirus software. Users on a tight budget might opt for the free version of Avira or one of the low-cost Norton 360 packages, which I suggest as the best antivirus software.

These tools, on the other hand, will assist you in determining whether or not you are infected.

In a hurry? Here are the top 5 online virus scanners:

  • The SafetyDetectives Known Vulnerabilities Scanner checks that your software is up to date with the latest updates by using the Common Vulnerabilities and Exposures (CVE) database.
  • Norton Power Eraser: Norton provides a free download of a useful tool that scans your computer, removes viruses, and searches for undesirable programs. It’s simple to set up and utilize.
  • VirusTotal: Use VirusTotal’s simple online interface to upload any suspicious file or investigate any questionable website. It has a 100% detection rate after cross-referencing 70 different malware and anti-phishing engines.
  • Bitdefender Free Mac Scanner: If you need to scan a Mac and remove any malware, PUPs, or unwanted programs, download this free utility. It’s simple to operate and doesn’t take up a lot of room.
  • ScanMyServer: This free internet service checks your website or server for security flaws and hacking proof. Paid users can scan several sites and receive daily findings, while free users get a weekly vulnerability report with recommended patches.

How I Rated the Top 5 Free Online Virus Scanners?

  • Ease of Use is a term used to describe how simple something is to use. All of these cybersecurity solutions have been thoroughly vetted to ensure that they are easy to use and will not infect your computer with bloatware or unwanted notifications.
  • True, the majority of free online virus scanners are useless. Every item on this list detects malware and eliminates it, or gives you important information to help you secure your computer.
  • Effectiveness.
    One of the reasons I was seeking good online antivirus scanners was because my machine couldn’t handle another CPU-intensive app. All of these cybersecurity tools are really light and won’t slow down your PC.
  • The cost.
    All of these items are completely free. They don’t hide their features behind a paywall like many ostensibly “free antivirus” programs do.

1. SafetyDetectives Known Vulnerabilities Scanner

The SafetyDetectives Known Vulnerabilities Scanner is one of the best totally online cybersecurity solutions available. It’s a quick and secure way to see if your computer is running any dangerous apps or if any of your programs require a security update.

The CVE database (Common Flaws and Exposures) was used to create the tool, which is the world’s largest collection of known cybersecurity vulnerabilities.

When a programmer or a cybersecurity researcher identifies a flaw in a program, they initially try to fix it. After this possible threat has been mitigated, it is reported to CVE so that any user can be aware of the vulnerabilities in their software and download the necessary updates to improve their security.

The SafetyDetectives vulnerability program compares the parameters of your browser and operating system to the CVE database and suggests patches based on these flaws.

There’s no need to download anything because this program is totally hosted by the SafetyDetectives website, and the scan takes only seconds. The Known Vulnerabilities Scanner will ensure you are as secure as possible without downloading any software (but you should absolutely have an antivirus installed).

Bottom Line:

The SafetyDetectives Known Vulnerabilities Scanner is a quick and easy way to check for known defects and vulnerabilities in system software. It provides step-by-step directions for patching certain vulnerabilities, based on the international CVE criteria. It’s fully free and entirely online, so there’s no need to download anything.

2. Norton Power Eraser 

Norton’s full-suite antivirus software is among the most effective available. Norton’s Power Eraser is a condensed version of their antivirus scanner that can be downloaded for free. It’s a thorough and effective antivirus scanner; during my testing, it discovered multiple PUPs and malware files, which it safely deleted from my PC.

Because the software is so basic, it’s really simple to use. Following the download, you may choose between a comprehensive rootkit scan or one of four advanced scanning options:

Scan for Unwanted Applications.

  • PUPs are detected in every software file and offered to be removed from the system.
  • Examine your online reputation.
  • Based on Norton’s malware database, scans a designated folder for known malicious files.
  • Scan the entire system.
  • Only looks for vulnerabilities in the operating system.
  • Multi-Boot Scan is a feature that allows you to scan many bootable media at the same time
  • For PCs with several operating systems, a more advanced version of the System Scan is available.

The rootkit scan took about 90 minutes and discovered 100% of the malware that had been cached on my machine. The Reputation Scan identified and deleted malware in the particular files I picked in a matter of seconds.

Although the Power Eraser is an effective scanning tool, it lacks some of the capabilities that make antivirus software so valuable.

Because there is no active scanning, a virus could be downloaded and executed without Power Eraser knowing.

There’s also no firewall, VPN, real-time protection, or scheduled scans – if you really want to be protected from cyber threats, consider one of Norton’s low-cost 360 plans, which all come with a 30-day money-back guarantee.

Bottom Line:

The most thorough free antivirus scanner tool available is Norton Power Eraser. It’s simple to download and install, and during testing, it found and eradicated all of the malware on my PC. Advanced scans can delete obnoxious programs and bloatware, analyze specific directories, and even analyze my operating system for malware.

3. VirusTotal 

VirusTotal is the greatest online-only virus scanner because it requires no download and is completely free. Even better, VirusTotal shares every piece of malware and every predatory website it finds with the global cybersecurity community, so by using it, you’re actually helping users all across the world.

The VirusTotal scanner isn’t like traditional antivirus software in that it doesn’t go through all of your files and directories looking for PUPs and malware. That’s simply not something a website can accomplish; if you want a comprehensive antivirus scan of your machine, you’ll need to download one.

The scanner from VirusTotal is much more straightforward: it examines any file or webpage that you enter into its internet portal.

Over 70 malware and anti-phishing engines from around the world are used in the scan – Microsoft, McAfee, Panda, Norton, and Comodo are just a few of the firms that have donated their engines to VirusTotal’s scanner.

It’s simple to use: simply upload a file or input a URL into VirusTotal, and the scanner will notify you if any of the 70 cybersecurity engines detects a problem.

I ran VirusTotal’s scanner against a variety of malware files, both fresh and old, and it accurately identified all of them.

It won’t remove anything from your computer; if you want to get rid of malware, you’ll need to install antivirus or anti-malware software.

Bottom Line:

The finest online-only virus scanner is VirusTotal. This is an excellent tool to use if you suspect you’ve downloaded malware or if you’re suspicious about a website. They collaborate with cybersecurity teams all around the world to construct a holistic picture of the threats that face computer users everywhere, ensuring that you don’t only get one antivirus scanner’s view on your suspicious data, but 70 distinct malware detection engines at the same time.

4. Bitdefender Virus Scanner for Mac

Believe me when I say that a growing number of hackers are dedicated to developing new malware to infiltrate macOS. Check out Bitdefender’s free Virus Scanner for Mac if your Mac is suffering delay, intrusive pop-ups, or security notifications.

Virus Scanner for Mac is a simple yet powerful virus detection and removal program. I infected my test Macbook with malware and PUPs, and the scanner recognized them all. It even found a couple of of.dmg files that Avast had overlooked!

There are three different scans available in Virus Scanner for Mac:

Scan for Critical Locations.

  • This is a quick scan that looks for viruses in the places where they usually try to hide.
  • On my device, the full system scan took about 30 minutes.
    Scan made to order.
  • Specific files or folders are scanned. I asked it to scan through my downloads folder as well as my recently downloaded torrents.

Bottom Line:

Bitdefender’s scanner is free and quite light, and it successfully identified and eradicated all malware from my test computer. However, numerous critical functions are lacking from this program, and I would never trust it to protect my Mac products. When premium Mac antiviruses like Intego are affordable and provide far greater protection, it’s simply not worth the trouble.

5. ScanMyServer 

ScanMyServer is a security solution that checks your website or server for vulnerabilities or security invasions every week, unlike the other items on this list. There are many excellent vulnerability scanning tools available, but ScanMyServer is free and completely online — no download is required.

ScanMyServer can scan your code for common vulnerabilities and offer you a detailed report, usually within a few hours of testing, if you’re concerned about the security of your website. There is a subscription service for people with numerous sites, but you can obtain a weekly report for free if you only have one.

You won’t receive the same user interface, personalized settings, or thorough data as leading vulnerability scanners like Mozilla Observatory or Qualys because it’s only available online.


ScanMyServer is a powerful web-based website and server vulnerability scanner. ScanMyServer is a vulnerability scanner that will keep you up to speed on the latest hacking risks if you have a website or a public server. It provides free weekly site health reports, and you may pay for a subscription to receive daily information on numerous sites.
