Antivirus software is a type of software that is designed to prevent, detect, and remove malware from a computer system. It is an essential tool for protecting your computer against viruses, worms, Trojans, spyware, adware, and other malicious software programs that can compromise your system's security and steal your personal information.
What is Antivirus Software?
Antivirus software is a program that is designed to scan your computer for viruses and other malicious software programs. The software uses a database of known viruses to identify and remove any threats that it finds. Antivirus software is essential for protecting your computer against malware, which can cause serious damage to your system and compromise your personal information.
How Does Antivirus Software Work?
Antivirus software works by scanning your computer for viruses and other malicious software programs. The software uses a database of known viruses to identify and remove any threats that it finds. Antivirus software also uses heuristics to identify new and unknown threats that may not be in the database.
Once the software has identified a threat, it can either remove it or quarantine it. If the software removes the threat, it deletes it from your computer. If the software quarantines the threat, it isolates it in a secure location on your computer so that it cannot cause any harm.
Types of Antivirus Software
There are two main types of antivirus software: signature-based and behavior-based.
Signature-based antivirus software uses a database of known viruses to identify and remove threats. This type of software is effective against known viruses but may not be able to identify new and unknown threats.
Behavior-based antivirus software, on the other hand, uses heuristics to identify new and unknown threats. This type of software is more effective against new and unknown threats but may also generate more false positives.
