Potentially unwanted software detected kaspersky

Unlike the in-depth articles in the Knowledge Base, every definition in the Glossary is succinct, while remaining highly informative. This section is currently under construction. In the Knowledge Base, you will find various articles about common threats, a general classification of malware and unwanted messages, and a brief historical overview of the evolution of these and many other threats.

The Knowledge Base now has three main sections: — The Detectable Objects section gives detailed information about malicious and potentially dangerous programs that we protect users against every single day all around the world, as well as advice on what to do in case of infection. However, this might be tacit consent. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

Potentially unwanted applications PUA are a category of software that can cause your machine to run slowly, display unexpected ads, or at worst, install other software that might be unexpected or unwanted.

PUA is not considered a virus, malware, or other type of threat, but it might perform actions on endpoints that adversely affect endpoint performance or use. The term PUA can also refer to an application that has a poor reputation, as assessed by Microsoft Defender for Endpoint, due to certain kinds of undesirable behavior. For more examples and a discussion of the criteria we use to label applications for special attention from security features, see How Microsoft identifies malware and potentially unwanted applications.

Potentially unwanted applications can increase the risk of your network being infected with actual malware, make malware infections harder to identify, or waste IT resources in cleaning them up.

The new Microsoft Edge , which is Chromium-based, blocks potentially unwanted application downloads and associated resource URLs. This feature is provided via Microsoft Defender SmartScreen.

Although potentially unwanted application protection in Microsoft Edge Chromium-based, version Under the Security section, turn on Block potentially unwanted apps. In addition, admins can configure Microsoft Defender SmartScreen as a whole, using group policy settings to turn Microsoft Defender SmartScreen on or off. Although Microsoft Defender for Endpoint has its own blocklist based upon a data set managed by Microsoft, you can customize this list based on your own threat intelligence.

If you create and manage indicators in the Microsoft Defender for Endpoint portal, Microsoft Defender SmartScreen respects the new settings. Microsoft Defender Antivirus blocks detected PUA files and any attempts to download, move, run, or install them. Blocked PUA files are then moved to quarantine. Malware, also known as "malicious software," can be classified several ways in order to distinguish the unique types of malware from each other. Distinguishing and classifying different types of malware from each other is important to better understanding how they can infect computers and devices, the threat level they pose and how to protect against them.

The classification system used by Kaspersky is also used by a number of other antivirus vendors as the basis for their classifications. Individual malware programs often include several malicious functions and propagation routines — and, without some additional classification rules, this could lead to confusion.

For example, a specific malicious program may be capable of being spread via an email attachment and also as files via P2P networks. The program may also have the ability to harvest email addresses from an infected computer, without the consent of the user.
