To reduce the risk of infection by file-encrypting malware and avoid false virus detections when you install applications and games, Kaspersky Lab specialists recommend to configure Kaspersky Total Security 2018 as follows:
Configure the rules for the Protected file types category on access of applications with high and low restrictions:
Enable System Watcher and adjust its settings so that Kaspersky Total Security 2018 can detect the launch of file-encrypting malware. The System Watcher component of Kaspersky Internet Security 2018 collects data about actions performed by applications on your computer and shares this information with other components for improved protection. When System Watcher is enabled, Kaspersky Total Security 2018 can detect and finish the malicious process. The file from which the process was run is sent to Quarantine.
File-encrypting malware gets encryption keys from the Internet. Block Internet access for Low Restricted, High Restricted, and Untrusted groups of applications to avoid such cases.
