Antivirus is a kind of software used to prevent, scan, detect and delete viruses from a computer. Once installed, most antivirus software runs automatically in the background to provide real-time protection against virus attacks.
Comprehensive virus protection programs help protect your files and hardware from malware such as worms, Trojan horses and spyware, and may also offer additional protection such as customizable firewalls and website blocking.
Antivirus software is a type of program designed and developed to protect computers from malware like viruses, computer worms, spyware, botnets, rootkits, keyloggers and such. Antivirus programs function to scan, detect and remove viruses from your computer. There are many versions and types of anti-virus programs that are on the market. However, the prime objective of any antivirus program is to protect computers and remove viruses once detected.
Most antivirus programs incorporate both automated and manual filtering abilities. The instant scanning option may check files – downloaded from the Internet, discs that are embedded into the PC, and files that are made by software installers. The programmed scanning process may likewise check the entire hard drive on a day-to-day basis. The manual scanning system enables you to check single documents or even to scan the complete network at whatever point you feel it is necessary.
How Antivirus work?
Antivirus software begins operating by checking your computer programs and files against a database of known types of malware. Since new viruses are constantly created and distributed by hackers, it will also scan computers for the possibility of new or unknown type of malware threats.
Typically, most programs will use three different detection devices: specific detection, which identifies known malware; generic detection, which looks for known parts or types of malware or patterns that are related by a common codebase; and heuristic detection, which scans for unknown viruses by identifying known suspicious file structures. When the program finds a file that contains a virus, it will usually quarantine it and/or mark it for deletion, making it inaccessible and removing the risk to your device
Features of an Effective Antivirus
The following features of any antivirus are to be looked for when you decide on installing one
Proactive scanning for malwares, and deleting once detected
Default-Deny Protection – Default-Deny protection that is implemented to prevent the entry of suspicious files by default.
Auto Sandbox Technology – A virtual environment where suspicious and unknown files are secluded and run to check for any malicious activity without interfering with the normal operations.
Containment Technology – Validates and authorizes the programs that are executable and ensures that the processes are run without effecting the regular operations of the system.
Host Intrusion Protection System (HIPS) – This feature works on a protocol-based intrusion prevention system, that oversees all the application and program activities that aare processed in the system. The HIPS terminates any malicious activities once found. This prevents the malware from infecting the operating system, registry keys or personal data or system memory.
Antiviruses are also of different types based on the OS compatibility
- Antivirus for Windows OS
- Antivirus for Linux OS
- Antivirus for Android OS
- Antivirus for MAC OS
What Does Antivirus Software Do?
Several different companies build antivirus software and what each offer can vary but all perform some essential functions:
- Scan specific files or directories for any malware or known malicious patterns
- Allow you to schedule scans to automatically run for you
- Allow you to initiate a scan of a particular file or your entire computer, or of a CD or flash drive at any time.
- Remove any malicious code detected –sometimes you will be notified of an infection and asked if you want to clean the file, other programs will automatically do this behind the scenes.
- Show you the ‘health’ of your computer
Always be sure you have the best, up-to-date security software installed to protect your computers, laptops, tablets, and smartphones.
Benefits of Antivirus Software
Antivirus solutions protect more than just laptops, office computers, smartphones and tablets. They protect precious memories, music and photo libraries, and important documents from destruction by malware. Make sure your protection is up to the challenge of defending against the latest threats.
Modern antivirus solutions are capable of:
- Detecting, blocking, and removing viruses, malware, and ransomware
- Preventing identity theft and block phishing and fraud
- Warning about dangerous websites and links before you click
- Scanning the Dark Web to find if an email address has been compromised
- Keeping online accounts protected with secure password encryption
- Providing simple training to teach you and your family how to be even safer online
- Tuning up your computer to keep it running smoothly, just like new
How Does Antivirus Software Work?
Many antivirus software programs still download malware definitions straight to your device and scan your files in search of matches. But since, as we mentioned, most malware regularly morphs in appearance to avoid detection, Webroot works differently. Instead of storing examples of recognized malware on your device, it stores malware definitions in the cloud. This allows us to take up less space, scan faster, and maintain a more robust threat library.
Free vs Paid Antivirus Software
From banking to baby photos, so much of our business and personal data live on our devices. If it were stored physically, paying for a security solution would be a no-brainer. Unfortunately, we often expect our online data to remain secure without lifting a finger or spending a cent. Companies claiming to do it for free are partly responsible for the confusion, to be sure. But consumers should insist on features like identity theft protection, mobile security, and support options when it comes to their data security, too—features usually lacking with free solutions. Free is not always better.
