Imagine – the year is 1992, the Soviet Union has just collapsed and Igor Danilov has a vision – to create the best antivirus software in the world. Igor and his team spend the next 10 years developing and refining his software until it finally exceeds his incredibly high standards – Dr. Web is born! Fast forward to today and you will find that this passion for excellence and innovation still drives the Dr. Web team. We continue creating dynamic and effective applications that protect YOU from cyberattack!

Igor Danilov knew that computer viruses were going to get worse, and become a major threat to the public – and this worried him greatly! He wanted, and still wants, to help people protect their computers, and safeguard the important things in their lives.

However, a fort can only be successful if it maintains and updates itself, and is easy to use. The average user, like you and me, doesn’t necessarily know – or even want to know how their automobile operates. We only want to get where we are going, easily, efficiently, and safely! The same applies to our computers! We want to turn them on, use them, enjoy them, and know that we are safe from a devastating virus attack.

Our philosophy is simple: to prevent, detect, and respond. And our technology is both complex and simple; complex on the inside, simple on the outside. Totally effective - yet easy to use!

We always follow the motto of Doctor Web's founder in everything we do: SECURITY WITHOUT COMPROMISES!

  1. Igor Danilov creates the first resident anti-virus monitor Tadpole.
