Nowadays, every computer user strives to find excellent antivirus software to keep their devices and data safe. However, finding one in the sea of available apps is not easy. 

If you are looking for a free solution to protect your devices and data from viruses and malicious files, you’ve come to the right place. ClamWin antivirus software is one of the most widely used free antivirus apps.

This ClamWin review will give you an insight into how efficient this antivirus program is, describing all its advantages and disadvantages. So let’s jump in!

What Is ClamWin?

ClamWin is a free and open-source antivirus program that offers anti-malware and anti-spyware protection, boasting a powerful virus scanner.

One of the benefits of this free antivirus program is its ability to scan your device for viruses every hour, day, or even week. It also allows you to schedule when scans should take place and which files should be scanned.

Currently, over 600,000 people worldwide use the ClamWin antivirus, and this review may help you decide whether you should join them or not.

Compatibility and Integration

This antivirus software integrates seamlessly with Microsoft Outlook and Windows Explorer, making it convenient to scan individual files, folders, and email attachments.

It supports various Windows OS versions, including:

  • Windows 7
  • Windows 8
  • Windows 10
  • Windows XP
  • Windows Vista
  • Windows 2000
  • Windows Server 2003
  • Windows Server 2008
  • Windows Server 2012

Unfortunately, it doesn’t support Android, Mac, or iOS devices.

Reliability and Security

ClamWin doesn’t offer real-time protection. This means you’ll have to scan and remove viruses from a file manually.

ClamWin antivirus is an open-source, cross-platform antivirus engine. It acquires its antivirus definitions from the ClamAV database.

You can adjust filters to prevent ClamWin from scanning certain file types or locations and limit the size of files that can be scanned.

If you want to create a scheduled scan, you must take the following steps:

  1. Open the ClamWin antivirus.
  2. Select Preferences from the menu.
  3. Click on Scheduled Scan to schedule a scan 
  4. Click the Add button.
  5. Enter the scheduling information in the Schedule window 
  6. Click OK

Although some limitations exist (for example, the slow scanning speed), the definitions database is updated several times each day. The program contains enough scanning options to guard against most viruses and malware.

Plans and Pricing

Virus protection provided by ClamWin antivirus is free and differs from other free antivirus software because it is open-source.

Setup and Ease of Use

This antivirus program is easy to use. It has a straightforward installation process, a simple menu bar, and a user-friendly interface

Users can schedule scanning, customise scanning filters, and decide whether they want to see updates each day, week, or month. They can also configure scanning rules for the Microsoft Outlook integration.

Customer Support

Even though this software is free, it has decent customer support — you’ll receive your answer within ten minutes. However, the only way to get support is through online forums. Unfortunately, there are no email, phone, or live chat options. 


In this section, we will compare ClamWin to its main competitors. So stick around if you want to find out which one of the following programs offers the best virus protection

ClamWin vs Avira

Avira offers free and paid versions, while ClamWin is completely free. Avira can protect you from a ransomware attack, while ClamWin provides anti-malware and anti-spyware protection.

ClamWin Antivirus is compatible with various Windows-based devices, while Avira is compatible with Windows, Android, iOS, and macOS.

Avira has a 100% malware detection rate, while ClamWin has only a 50% protection score. All this indicates that Avira is the winner.

ClamWin vs Malwarebytes

Both Malwarebytes and ClamWin don’t include a real-time protection feature. 

As for Malwarebytes scanning, it takes on average 90 seconds. ClamWin’s scanning speed, on the other hand, lasts one minute and two seconds. 

To access all Malwarebytes’s features, you’ll need to pay after your trial period. ClamWin, on the flip side, gives you access to all its features free of charge. 

ClamWin vs Bitdefender

The Bitdefender antivirus software comes with a full-featured virtual private network, while ClamWin free antivirus doesn’t.

The Bitdefender’s firewall blocks web-based port scans accurately and issues a port scan warning when needed. It also offers the Paranoid Mode to notify you when an unknown program tries to access your computer. Both of these features are not available in ClamWin. 

According to my research, ClamWin isn’t the best security software out there. So, if you’re looking for advanced security features, Bitdefender is the better choice. 

User Reviews

ClamWin is rated 4.6 out of 5 stars on SourceForge. Here is what users had to say about this antivirus program:

As you can see, customers seem to be rather satisfied with ClamWin. However, keep in mind that these reviews are not very recent. In my opinion, ClamWin is a decent but not the best antivirus software out there.

Wrap Up

While this free antivirus program is considered one of the most useful open-source programs, it offers only basic antivirus protection. This is the case with most free antivirus programs — they don’t offer advanced features. 

However, if you wish to avoid paying for an antivirus program, consider trying ClamWin first. Why? Because it is capable of protecting your computer from infected files and viruses. What’s more, most users are very satisfied with its performance. 

Hopefully, this ClamWin antivirus review provided you with enough info to determine whether this antivirus software is a good fit for you.
