WHAT IS SPAM?
It is an unwanted, junk, unsolicited message sent in bulk, usually through email. It can also occur
through other communication channels such as instant messaging, social media, text messages
(SMS), and forums.
Some spam messages are designed to reach a large audience for commercial purposes, such
as advertising products or services, while others may contain malicious links or attachments. A
person who creates spam is called a spammer. Most email services automatically shift the spam
mail into a spam folder of a mailbox.
You can also avoid getting spam messages by following the given steps:

Many early infectious programs, including the first Internet Worm, were written as experiments
or pranks.
There are different types of malwares designed for different purposes. Some of the common
types of malwares are virus, worm, Trojan, etc.
Virus
VIRUS is an acronym for Vital Information Resource Under Siege. It is malicious software that
is generally attached to a file. When this file enters your system, the virus will start infecting
your computer. It has the ability to spread from one host to another and is dormant after being
downloaded unless it is opened and used. Viruses are responsible for disrupting the operations
of systems and can even cause data loss. For example, the Melissa virus, released in 1999, was
one of the first email-aware viruses. A virus gains access to your computer through various
means, such as:
By downloading infected files.
By using infected pen drives, CDs, or DVDs.
By opening an infected file attachment of emails.
Browsing on insecure websites.
