How Does Antivirus Work?
Antivirus is a computer program that protects you against viruses, spyware and other malicious software. It can also monitor your activities online and detect any cyber threats you might be experiencing. This is one of the most important parts of your online security strategy.
While there are different types of antivirus, all of them work by scanning and detecting the presence of a virus on your computer. They then quarantine the infected file or application. Some antivirus programs may also block access to harmful websites.
When a device becomes infected, it can cause major damage to the system. This can include erasing data or damaging a server. These viruses can also lead to follow-on attacks on your identity and finances.
Viruses are created and updated regularly. In addition, hackers have more sophisticated ways to gain access to your device. Usually, they disguise themselves as trusted sources to get personal information. The stolen information can then be used for phishing scams or identity theft.
Antivirus programs use deep learning and artificial intelligence to detect threats and remove them. These technologies can keep up with the constant changes and evolution of malware.
Modern antivirus solutions also incorporate cloud-based detection. This method relies on a database of file signatures to determine if a virus is present on a device. If the signature matches a known virus, the software will quarantine it.
Signature-based detection is a popular method for detecting malware. However, this method is not very effective when new viruses emerge.
