About Us

SpyWarrior is an anti-malware program developed by UAB „Kibernetinio saugumo sistemos”. It is a Lithuanian company that, together with partners in Vilnius University of Applied Sciences (VIKO), developed an anti-virus program for Windows computers. The developed product has received investments from the EU.

Our goal is to revolutionize the malware detection industry by fundamentally changing computer security. We have developed SpyWarrior, an anti-virus program based on a model that is yet to be used in the industry.

The program improves computer performance and is quick to detect and remove all potential threats. The developed AI algorithms automate malware detection and malware action categorization/inclusion in the malware database. All of this makes it possible to quickly detect and remove new malware from users’ computers.


The program is currently only available for Microsoft Windows users. All popular browsers, such as Google Chrome, Mozilla Firefox, Internet Explorer and Opera are supported.
