Malware is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the user's computer security and privacy. Researchers tend to classify malware into one or more sub-types.
A key generator (key-gen) is a computer program that generates a product licensing key, such as a serial number, necessary to activate for use of a software application. Keygens may be legitimately distributed by software manufacturers for licensing software in commercial environments where software has been licensed in bulk for an entire site or enterprise, or they may be developed and distributed illegitimately in circumstances of copyright infringement or software piracy.
A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed and often masks its existence or the existence of other software. The term rootkit is a compound of "root" and the word "kit". The term "rootkit" has negative connotations through its association with malware.
Antivirus software, also known as anti-malware, is a computer program used to prevent, detect, and remove malware.
Linux malware includes viruses, Trojans, worms and other types of malware that affect the Linux family of operating systems. Linux, Unix and other Unix-like computer operating systems are generally regarded as very well-protected against, but not immune to, computer viruses.
ESET, s.r.o., is a Slovak software company specializing in cybersecurity. ESET's security products are made in Europe and provide security software in over 200 countries and territories worldwide, and its software is localized into more than 30 languages.
Scareware is a form of malware which uses social engineering to cause shock, anxiety, or the perception of a threat in order to manipulate users into buying unwanted software. Scareware is part of a class of malicious software that includes rogue security software, ransomware and other scam software that tricks users into believing their computer is infected with a virus, then suggests that they download and pay for fake antivirus software to remove it. Usually the virus is fictional and the software is non-functional or malware itself. According to the Anti-Phishing Working Group, the number of scareware packages in circulation rose from 2,850 to 9,287 in the second half of 2008. In the first half of 2009, the APWG identified a 585% increase in scareware programs.
Rogue security software is a form of malicious software and internet fraud that misleads users into believing there is a virus on their computer and aims to convince them to pay for a fake malware removal tool that actually installs malware on their computer. It is a form of scareware that manipulates users through fear, and a form of ransomware. Rogue security software has been a serious security threat in desktop computing since 2008. An early example that gained infamy was SpySheriff and its clones, such as Nava Shield.
Kaspersky Anti-Virus is a proprietary antivirus program developed by Kaspersky Lab. It is designed to protect users from malware and is primarily designed for computers running Microsoft Windows and macOS, although a version for Linux is available for business consumers.
Kaspersky Internet Security was an internet security suite developed by Kaspersky Lab compatible with Microsoft Windows and Mac OS X. Kaspersky Internet Security offers protection from malware, as well as email spam, phishing and hacking attempts, and data leaks. Kaspersky Lab Diagnostics results are distributed to relevant developers through the MIT License.
VirusTotal is a website created by the Spanish security company Hispasec Sistemas. Launched in June 2004, it was acquired by Google in September 2012. The company's ownership switched in January 2018 to Chronicle, a subsidiary of Google.
A computer virus is a type of malware that, when executed, replicates itself by modifying other computer programs and inserting its own code into those programs. If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses.
Kaspersky Lab is a Russian multinational cybersecurity and anti-virus provider headquartered in Moscow, Russia, and operated by a holding company in the United Kingdom.

They are best known for Genieo, an application of this type. They also own and operate InstallMac which distributes additional 'optional' search modifying software with other applications. In 2014, Genieo Innovation was acquired for $34 million by Somoto, another company which "bundles legitimate applications with offers for additional third party applications that may be unwanted by the user". This sector of the Israeli software industry is frequently referred to as Download Valley.
Multiscanning is running multiple anti-malware or antivirus engines concurrently. Traditionally, only a single engine can actively scan a system at a given time. Using multiple engines simultaneously can result in conflicts that lead to system freezes and application failures. However, a number of security applications and application suites have optimized multiple engines to work together.
Sality is the classification for a family of malicious software (malware), which infects Microsoft Windows systems files. Sality was first discovered in 2003 and has advanced to become a dynamic, enduring and full-featured form of malicious code. Systems infected with Sality may communicate over a peer-to-peer (P2P) network to form a botnet to relay spam, proxying of communications, exfiltrating sensitive data, compromising web servers and/or coordinating distributed computing tasks to process intensive tasks. Since 2010, certain variants of Sality have also incorporated rootkit functions as part of an ongoing evolution of the malware family. Because of its continued development and capabilities, Sality is considered one of the most complex and formidable forms of malware to date.
Fileless malware is a variant of computer related malicious software that exists exclusively as a computer memory-based artifact i.e. in RAM. It does not write any part of its activity to the computer's hard drive, thus increasing its ability to evade antivirus software that incorporate file-based whitelisting, signature detection, hardware verification, pattern-analysis, time-stamping, etc., and leaving very little evidence that could be used by digital forensic investigators to identify illegitimate activity. Malware of this type is designed to work in memory, so its existence on the system lasts only until the system is rebooted.
Trojan.Win32.DNSChanger is a backdoor trojan that redirects users to various malicious websites through the means of altering the DNS settings of a victim's computer. The malware strain was first discovered by Microsoft Malware Protection Center on December 7, 2006 and later detected by McAfee Labs on April 19, 2009.
Kaspersky Lab has faced controversy over allegations that it has engaged with the Russian Federal Security Service (FSB) to use its software to scan computers worldwide for material of interest—ties which the company has actively denied. The U.S. Department of Homeland Security banned Kaspersky products from all government departments on 13 September 2017, alleging that Kaspersky Lab had worked on secret projects with Russia's Federal Security Service (FSB). In October 2017, subsequent reports alleged that hackers working for the Russian government stole confidential data from the home computer of a National Security Agency (NSA) contractor in 2015 via Kaspersky antivirus software. Kaspersky denied the allegations, stating that the software had detected Equation Group malware samples which it uploaded to its servers for analysis in its normal course of operation.
