What is antivirus? How it protects your PC?

What is antivirus software?

 Antivirus software, or as it is most commonly known today, anti-malware software, is a tool that searches for applications that run on your PC or smartphone that should not be there. (A virus) this includes threats like ransmware, Trojan, worm, malware, spyware, root kit infections, spyware, keyloggers, adware, etc.

 It uses a number of methods to differentiate between the Word document you are editing and unpleasant software that will throw annoying pop-up ads or steal your bank details.

 How antivirus software works?

 

Any system that is without an antivirus vulnerable to malware infection when connected to the Internet. Also, when a user clicks on suspicious links or attachments that are sent through emails, the system is vulnerable to malicious attacks.

 The antivirus analyzes suspicious files and compares the code of the files with the code of the database. If the code pattern is identical to the malicious code known in the database, the suspicious file is considered malware and the antivirus deletes it.

All program files are scanned as they enter the system with the help of the antivirus scanning system. Executable codes that match signatures are considered viruses and are blacklisted. The other files are passed through Defense + and Host Intrusion Prevention Systems / This allows known files and unknown files to be quarantined with the Defense + Sandbox System. Files that are quarantined are restricted to run in a particular environment. Good files are added to the White List, while isolates are passed to the laboratory analysis.


The beauty of malware for hackers is their ability to access or damage a computer without our knowledge. It is important to know the different types of malicious codes, or "malware", against which antivirus software is designed to protect:
Spyware: theft of confidential information
Ransomware: extorting money Virus Worms: dissemination of copies among Trojan computers: they promise one thing but deliver another
Adware: Spam advertising
