ANTIVIRUS
A security program designed to prevent, detect, search and remove malware from computers is
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
anti-virus 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.

McAfee, Symantec, Kaspersky, etc.
