Ikarus is an Austrian antivirus program, geared more toward professionals.
It’s relatively unknown to the general public but very well known in Austria.
The product is very easy to use—just a database, and that’s it!
Despite that, let’s see what it can do.



Interface :

As I mentioned in the introduction, IKARUS is a fairly simple antivirus program.
No HIPS, no defenses against attacks, no machine learning AI—nothing at all!
This can be a drawback because a database quickly becomes completely obsolete with the billions of pieces of malware that emerge every day. It just has an AMSI system to analyze network attacks.
Ikarus doesn’t even offer any settings!
Nevertheless, it’s very lightweight.

Malware URL : 7/9
Two URLs got through the protection, and one URL didn't work.
Other than that, Ikarus blocked the rest.

Malware Pack : 21 out of 69 threats remain
Even though Ikarus doesn't offer very advanced defenses, it managed to defend itself!
And thank goodness!
With AMSI, it managed to block several payloads that were being downloaded and even a DotNet attack!
Although this is a pleasant surprise, the machine is infected with malware that patches the CasPol.exe process.

Final scan :
Ikarus : 0
Symantec : 4
Emsisoft : 7
KVRT : There were some issues with the file; I couldn't use it, so I skipped it.

Final opinion:

The product holds its own. It has a relatively robust database, and its detection rates are high.
Although Ikarus has held its own, it lacks key defenses to counter certain unknown malware.
And that's really a shame...
However, it can provide excellent protection when paired with a good firewall or antimalware program.

I love how rapid ikarus is to update its database based on verdicts from other AV vendors on VT. Thank You for the test.
 
"However, it can provide excellent protection when paired with a good firewall or antimalware program."
Shadowra,What good firewall or antimalware program(s) would you recommend?

Firewall: The one that comes with Windows is already good. You can install management software like Malwarebytes if you want alerts :)

Anti-Malware: SiriusLLM ( @danb ) or Malwarebytes
 
Great test again! I remember the days Emsisoft used Ikarus, the good old days before it became a huge polished :poop:

WFC Windows Firewall Control by malwarebytes is a excellent firewall and regularly updated. Dev is active on Wilders and responds to issues/bug fixes quickly.

Before was also TinyWall but abandoned, Spyshelter, and other niece firewall apps like Minimal Firewall..

Minimal Firewall indeed seems abandoned Serious Discussion - Minimal Firewall
Currently I'm using MalwareBytes / Binisoft Windows Firewall Control as Windows Firewall front-end coupled, as additional protection, with the 3rd party firewall Windows 11 Firewall Control v. 9 Plus Edition (formerly Sphinx Software Windows 10 Firewall Control v. 8).
About the latter I wrote a post on its dedicated thread just over a year ago Advice Request - Windows 10 Firewall Control - Sphinx Software - opinions ?
The official Sphinx Software website is now closed and Windows 11 Firewall Control v. 9 is only available from GitHub at GitHub - Windows11FirewallControl/Windows11FirewallControl: Simple and exhaustive solution for applications network activity controlling and monitoring.
The downloads webpage is at Windows11FirewallControl/precompiled at main · Windows11FirewallControl/Windows11FirewallControl
Windows 11 Firewall Control v. 9 hasn't been updated since its official release ( June 30, 2025) but it's working well and the developer is quick in responding to users' questions or in fixing possible bugs.
Compared to the Windows Firewall, Windows 11 Firewall Control v. 9 has some additional features like telemetry blocking, a list of predefined, ready-to-use, applications permissions Security zones and it can Allow / Block domains per-app or globally.
Both MalwareBytes / Binisoft Windows Firewall Control and Windows 11 Firewall Control v. 9 are free of charge.

Apart from the predefined Security zones you can manually customize Windows 11 Firewall Control v. 9 rules. Just as example the attached screenshot shows a rule which I customized when Folder Monitor asked to connect to its domain to a unsecured port (port 80) . W11FC v. 9 paused the connection, effectively preventing it, and allowing the user to make a choice. I preferred to disable the connection under "Result" drop-down menu, then I clicked on OK to save the rule.
