IS USING INTERNET SAFE?

Let’s get a brief of Trojan, whether it’s a virus or malware and how to protect it using an antivirus
Beware of Greeks who bring gifts
In Virgil's epic poem The Aeneid, a clever Greek military
strategist named Ulysses devises a plan for his men to enter the walled city of
Troy. Instead of destroying or scaling the city walls, Ulysses sees another way
to enter: with a deception. Trojan soldiers watch as the Greeks appear to
leave, leaving behind a giant wooden horse in surrender. Drunk after victory,
the Trojans drive the horse into the walled city, only to discover that
Odysseus and his men had been hiding inside the entire time.
Like their namesake, Trojan horse attacks, or simply
Trojans, use deception and social engineering to trick unsuspecting users into
running seemingly harmless programs that conceal a malicious payload.
How
to Distinguish a Trojan
People sometimes think of a Trojan as a virus or a worm,
but in reality it is neither. A virus infects files that can replicate itself
and spread by attaching itself to another program. Worms are a type of malware
similar to viruses, but they do not need to attach to another program to
spread. Most viruses are now seen as inherited threats from the past. Worms
have also become more rare, although they do appear from time to time.
Consider Trojans as a general term for various ways of
spreading malware, as there are several types of Trojans. Depending on the
intent of the criminal programmer, a Trojan can be like a hack knife, acting as
a standalone malware, or as a tool for other activities, such as spreading
future payloads, communicating with the hacker later, or opening the system to
attacks as the Greek soldiers did from within the fortified Troy.
In other words, a Trojan is a propagation strategy used by
hackers to deliver a series of threats, from ransomware that demands money
immediately, to spyware that hides while stealing confidential information such
as personal and financial data.
Remember that adware or potentially unwanted programs (PUPs
or potentially unwanted programs) can be confused with Trojans because their
propagation method is similar. For example, adware sometimes sneaks onto your
computer as part of a software package. You think you are downloading one piece
of software, but actually it is two or three. The program authors typically
include adware for partner marketing reasons, so that they can earn money from
its installer through generally clearly identified offers. Such adware packages
are generally less malicious than Trojans. Also, they are not hidden like
Trojans do. But since the adware delivery vector resembles that of a Trojan, it
can cause confusion.

Infection Methods
Trojans can present themselves in any form, from free
software and music, to seemingly legitimate applications and browser ads.
Various reckless behaviors of users can lead to the infection of a Trojan. These
are some examples:
Download
manipulated applications: The promise of a free illegal copy of
software can be tempting, but unprotected software or a faulty activation key
generator can hide a Trojan attack.
Download
unknown freeware: What looks like a free game or screensaver
may actually be a Trojan, especially if you find it on an unreliable site.
Open
infected attachments: You receive a strange email with what looks
like an important attachment such as an invoice or delivery confirmation, but
it launches a Trojan when you click on it.
Visiting
questionable websites: Some sites only take a moment to infect
your computer. Others use tricks like pretending to stream a popular movie, but
only if you download a certain video codec, which is actually a Trojan.
Any other social engineering that is hidden taking
advantage of the latest trends. For example, in December, a large installed
base of Intel processors was found to be vulnerable to attack due to certain
hardware errors. Hackers took advantage of the ensuing panic by forging a patch
called Smoke Loader, which installed a Trojan.
All these threats and unwanted files that are being
downloaded in our system can be stopped using an updated antivirus and keep you
secure from all the crimes and informational data leakage.
