Kaspersky System Checker can check firewall and antivirus software settings, hardware components and drivers installed for them, critical system updates, user accounts, size of redundant temporary files, and so on.

In addition, Kaspersky System Checker is equipped with tools providing detailed information about the computer, displaying information about installed extensions for browsers or allowing to remove applications installed on the computer.
