MALWARE
Malware is a type of malicious program designed to damage or carryout other unwanted
actions on a computer system. In Spanish, 'mal' is a prefix meaning 'bad,' making the term
'badware,' which is a good way to remember it.
There are different types of malware programs that can affect the computer.
VIRUS
Virus stands for Vital Information Resources Under Seize. It is the kind of malware that
is created deliberately to damage critical information and data. It interferes with the
normal operation of a computer and attaches itself to any type of file. Due to this, when
we copy a file which has a virus, our computer gets infected. Before we know about it,
our computer starts malfunctioning, and our files and operating systems tend to get
damaged.
