Every gamer knows what Steam is and more than likely uses it. Steam accounts are also bought and sold for real money, which makes them very attractive to cyber-criminals. We’ve already discussed this and made a simple recommendation: If you like computer games, don’t neglect your cyber-security. That means you should never turn off your antivirus while gaming or chatting. Never!
From time to time, however, people complain that antivirus software slows down their computers, affecting their gaming. That’s why we want to explain how to set up Kaspersky Internet Security 2017 to work effectively and without slowing down Steam or other game libraries.
Our developers have marked Steam as a trusted group in all our solutions by default. That’s why Kaspersky Internet Security 2017 doesn’t affect games and Steam performance if you haven’t changed these settings manually.
But sometimes Kaspersky Internet Security 2017 blocks some software from launching. This might happen if, for example, you downloaded a program from an unknown source. If you think that Kaspersky Internet Security 2017 is blocking Steam or Steam games, check the Application Restriction rules.
