Farooq Alvi, from Pakistan, who were only 17 and 24 years old at the time. They named it “Brain”.
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.
