Many computer users believe antivirus software necessary, particularly when accessing online content and downloading files or programs. Not all antivirus utilities are created equal: some provide more features than just virus detection.

Virus Detection
The principal role of antivirus software is to detect and remove computer viruses. This is typically achieved by scanning files on your computer and comparing data in the documents to a database of known virus signatures. This database is updated frequently, often several times every day, to make certain that your antivirus program has the most up-to-date virus definitions to detect all known virus threats.

System Analysis
Most antivirus software has the capability to detect viruses both during a scan and in real time at the stage of disease. Many antivirus programs also track your computer for signs that system components aren’t functioning correctly. Upon recognizing system conditions that are probably caused by a virus, the antivirus software can initiate a scan to detect the cause of the issue. If the scan detects a virus, the infected file will be quarantined, deleted, or otherwise handled.

Malware Removal
Some antivirus software also detects and removes malware and other dangerous programs that may be installed in your computer. Independent malware scanners were needed in the past because of coding differences between virus malware and programs, leading to computer users who just set up an antivirus becoming infected. A growing number of antivirus programs now include malware detection and removal to provide more complete protection to your computer.

File Quarantine
The ability to quarantine files without deleting them is a significant characteristic of several antivirus programs because quarantines help safeguard your computer against false positives during virus scans. A false positive occurs when a program or document that’s not infected is identified by your antivirus as a virus file and action is taken against it. If your antivirus is installed to quarantine files for later inspection, the detected file is cut away from program resources but isn’t deleted until you manually decide to delete it. If the file is secure you have the option of removing it from quarantine and protecting it from potential detection.

Threat Identification
As new viruses and malware threats are published, antivirus programs can assist in their identification. If your antivirus has the ability to recognize potential dangers that are not in its virus definition database it may send a duplicate of the possible threat. This speeds up the process of new viruses being formally identified and added to virus definition files, ensuring more complete coverage not only for you but for others also.

Online Security
As a few antivirus software helps protect against malware and other dangers, some applications also feature elements that help in different ways to keep you safe online. Built-in intrusion detection, fraud monitoring, and phishing recognition alert you if someone tries to access your computer from a remote location or if a site attempts to divert your untrustworthy websites or pages with potentially harmful downloads might be blocked, protecting your computer by preventing the harmful actions before the website can load.

Data Protection
Because there’s still a possibility of file corruption or other damage if a virus is not detected immediately, some antivirus software provides online copies of crucial files which can later be restored.
