In this diagram, we see that most computers in our selection run home versions of Windows 7 圆4. Information about the operating systems and browsers installed on users’ computers We looked at which browsers are installed by users according to operating system. In 50-60% of cases, the latest versions of browsers are installed on computers.Only about 10% of users simultaneously use two or more browsers on the same computer.This result is in line with the findings of several other studies ( ). Google Chrome has the highest number of users. The popularity rating for browsers installed on users’ computers The most popular browserįor starters, here are the figures showing the popularity of different browsers installed on our sample computers: Browser

By analyzing the KSN data, we can obtain statistics about the browsers installed on our client’s computers. by a web browser that is trying to access them, KSN receives information about the name of the browser and its MD5. When web-based threats such as malicious scripts, exploits and infected files are detected on a server, etc. These computers regularly supply KSN ( ) with information about malicious code detected on the Internet.

This information is subsequently used to block unknown malicious programs, which is again done via the cloud.įor research purposes, we singled out 10.5 million computers in various locations around the globe. KSN, Kaspersky Lab’s cloud service, collects anonymous statistics about any threat detected on the computers of those who agree to have their data collected and transferred.

We assumed that the threats posed to users were unaffected by their choice of browser and undertook a little research to test this assumption. There is a simple reason for this popularity: exploits of vulnerabilities found in these products can infect computers regardless of which operating systems and browsers are used on the attacked machines. Today, cybercriminals are quick to exploit vulnerabilities in Adobe Reader, Flash and Java to infect users’ computers.
