Antivirus & Malware Protection Software

Antivirus or anti-virus software, also known as anti-malware software, is computer software used to prevent, detect and remove malicious software.

As the name suggests, antivirus software was initially developed to detect and remove computer viruses. However, with the increase of other kinds of malware, antivirus software started proving advanced protection from other computer threats. In particular, modern antivirus software can protect from: malicious Browser Helper Objects (BHOs), browser hijackers, ransomware, key loggers, backdoors, rootkits, Trojan horses, worms, malicious LSPs, dialers, fraud tools, adware and other spyware. Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, social engineering techniques, Advanced Persistent Threat (APT), online identity theft (privacy), online banking attacks, botnets DDoS attacks

Virus & Malware Detection Methods
There are several techniques which antivirus engines use to identify viruses & malware:

Signature-based identification
Out-of-date antivirus software relies heavily upon signatures to identify malware. Substantially, when a malware reaches an antivirus firm, it is analyzed by malware scientists or by dynamic analysis systems. Then, once it is confirmed to be a malware, a proper signature of the file is extracted and added to the signatures database of the antivirus software, which in turn is updated with the antivirus software users, at the time of their periodic update. When a particular file has to be scanned, the antivirus engine compares the contents of the file with all the available malware signatures in the it’s database. If the file matches one signature, then the engine knows which malware it is and performs predefined procedure in order to cleanse the infection.

Signature-based detection method can be very effective but, clearly, cannot defend against malware unless some of its samples have already been obtained, a proper signature generated and the antivirus product updated with the related malware information and its counter defense actions. Signature-based detection systems rely on the idea that, the more infective a malware is, the faster arrives in the hands of security researchers. Thus, even if it does not guarantee perfect defense, it protects from the most widespread threats. However, this approach is not really effective against next-generation malware, i.e. malware that has not been yet encountered or analyzed by the antivirus provider.

Heuristics Analysis Method
Advanced antivirus software uses heuristic analysis to identify new malware or variants of known malware, unlike signature based identification methods. Many viruses start as a single infection and through either mutation or improvements by other attackers, can grow into dozens of slightly different strains, called variants. Generic detection refers to the detection and removal of multiple threats using a single virus definition.

While it may be advantageous to identify a specific virus, it can be faster to detect a virus family through a generic signature or through an inaccurate match to an existing signature. Virus researchers find common areas that all viruses in a family share distinctively and can thus create a single generic signature. These signatures often contain non-contiguous code, using wildcard characters where differences exist. These wildcards allow the scanner to detect viruses even if they are padded with extra, meaningless codes. A detection that uses this method is said to be "heuristic detection or heuristics analysis method."

Rootkit Detection Method
Latest anti-virus software attempts to scan for rootkits. A rootkit is a type of malware planned to gain administrative level or privilege user control over a computer system without being spotted. Rootkits can change how the operating system functions and in some cases can tamper with the installed anti-virus program and render it useless. Rootkits are also more difficult to remove, in some cases requiring a complete format and re-installation of the operating system.

Real-time protection
Live shield, Real-time protection, on-access scanning, background guard, resident shield, auto-protect, and other synonyms refer to the automatic protection provided by most antivirus, anti-spyware, and other anti-malware programs. This monitors computer systems for suspicious activity such as computer viruses, spyware, adware, and other malicious objects in 'real-time', example, when inserting a CD, browsing the web, opening an email, or when a file already saved on the computer is opened or executed.

Alternative solutions
Alternative solutions to standard Antivirus Products Apart from the installed antivirus solutions, running on individual computers, alternative solutions are also used, including: Cloud-based antivirus and on-line scanners, Unified Threat Management (UTM), hardware and network firewalls.

Hardware and network firewall
Network firewalls thwart unfamiliar programs and processes from accessing the protected system or network. However, they are not antivirus systems and make no attempt to identify or eliminate any suspicious processes. They may protect against infection from outside the protected computer or network, and limit the activity of any malicious software which is found by blocking incoming or outgoing requests on predefined TCP/IP ports. A firewall is designed to deal with broader system threats that come from network connections into the system and is not an alternative to a virus protection system.

Cloud antivirus protection solutions
Cloud antivirus is a method which deploys lightweight agent software on the protected computer, while offloading the majority of data analysis to the antivirus provider's infrastructure. One approach to realizing cloud antivirus involves scanning suspicious files using multiple antivirus engines. Parallel scanning of files using potentially incompatible antivirus scanners is achieved by laying a virtual machine per detection engine and therefore eradicating any possible issues. Cloud antivirus can also perform "retrospective detection," whereby the cloud detection engine rescans all files in its file access history whenever a new threat is identified thus improving new threat detection speed. Cloud antivirus is a solution for effective virus scanning on devices that lack the computing power to perform the scans by themselves.

Online Virus scanning
Some antivirus vendors maintain websites with free online scanning options for the entire computer, or only critical areas, or local disks, folders or files. Regular online scanning is an additional scanning or backup assurance for those that run antivirus applications on their computers because those applications are often slow to catch threats. One of the first things that malicious software does in an attack is disable any existing antivirus software and sometimes the only way to know of an attack is by turning to an online resource that is not installed on the infected computer.

Specialist Virus removal tools
Virus removal tools are offered to help remove obstinate infections or certain types of infection. A rescue disk that is bootable, such as a CD or USB storage device, can be used to run antivirus software outside of the installed operating system, in order to remove infections while they are inactive. A bootable antivirus disk can be useful when, for example, the installed operating system is no longer bootable or has malware that is repelling all attempts to be removed by the installed antivirus software.
