ANTIVIRUS
A set of programs that identify and remove malware are
known as antivirus software. You must have an antivirus
software installed on your computer. It detects the virus in
the computer and does not let the virus copy itself on your
computer system.
Hundreds of new viruses are developed every hour. Antivirus
software developers regularly release updates on the
Internet that allow their programs to detect the latest known
viruses. You can update your copy of antivirus only through
the Internet. So, it is essential to have an Internet connection
to update antivirus software.
Some well-known antivirus programs are Norton, Quick Heal, AVG, McAfee, Symantec, Kaspersky,
etc.
