Computer security has been a very big challenge for a while now. As the world is going digital so as the security threat increasing.

Jeff is a 15-year-old teen who has unintentionally trashed his father’s personal computer five times .

Firstly as a game lover he downloaded a free video game.

This game came with embedded adware that overwhelmed him with pop up ads and slowed down almost everything, the game also contained a Trojan program that let spammers from a remote area to take over his computer and used it to forward junk emails.

Two months later, Jeff responded to what looked like a legitimate email asking him to update his Twitter login information. That phisher then used Jeff’s login to post links to adware to Jeff’s Twitter followers.

Not quite long after that, Jeff clicked yes to install a security software when a pop-up announced that his computer was infected with adware.

As you have probably guessed, that software installed more adware.

Jeff’s father has spent time, and money fixing his personal computer that he is beginning to wonder if the internet is really worth the aggravation.

What he is sure of is that computer security has become a lot more complicated than it used to be.

As the number of netizens is swiftly developing so is the security threat.

“netizen is a citizen of cyberspace (ie. The internet ). A person using the internet to participate in online social communities. When you confirm a new friend on Facebook you are expanding your online social group. You are being a good netizen! “

In this article we are going to discuss in details computer security focusing on virus as one of the main categories of Malware.

Sometimes people use these two words interchangeably, malware and virus. However, we will start by discussing malware first to enable us understand the differences.

Malware is a generic term for a piece of malicious code. This is programming code specifically developed to harm a computer or its data.

In Spanish “mal” means bad eg. Malcontents. Nothing good ever starts with “mal” malware is literally bad software.

 

In the world of malware, there are nine main categories.

  • Viruses
  • Worms
  • Trojans
  • Bot armies
  • Keystroke loggers
  • Spyware
  • Scareware
  • Adware
  • Ransomware

Our main focus is going to be on viruses, like we mentioned earlier in this article.

Virus

A Computer virus is a set of computer instructions that self replicate. A virus can be a complete program (a file to itself) or a piece of code (just part of a computer program file).

Some viruses are designed to spread only in a certain circumstances, like on a certain date.

While some viruses carry a payload that tells the virus to do damages like deleting files or attack other systems.

What makes your computer to be vulnerable?

Are you aware that when you buy a new computer that there are certain things to be done before using the system?,

a new computer is not secure, you should never think of removing a new system from the box to connect to the internet without taking some necessary steps to protect it.

In fact, your new computer is characterized with numerous security holes, which are flaws in the way your computer’s program have been written, that would make your computer vulnerable to attack.

The level of flaws in the code determines how much access an attacker or attacker’s malware can gain.

Security hole is any flaw in the way a computer program is written or used that makes your computer vulnerable to attack. It is also referred to as Security vulnerability by security experts

Are you wondering why computer has holes before you use it?

The reason is because computer run on programs that is made up of tens of millions of lines of codes that tells the computer what to do and this code is written by human programmers.

Those programmers can make mistakes that can be leveraged by hackers to gain unauthorized access to your computer.

This may sound strange but the truth is that programmers don’t think like criminals, no body taught them how to write secure code, that is because no programmer is interested in breaking into any system or anyone’s computer.

Since all the computer systems have security holes, you must protect yourself and patch those holes before you start surfing the internet, downloading softwares or gaming.

Warning! 
Once you are connected to the internet, an unprotected PC can fall victim to an attack in as little as 14 seconds! Protect your PC before you surf.

Before buying a computer, make sure you have plans for your virus protection softwares (anti-virus ),

you also need to install any security patches that have been issued by the operating system and software you plan to use.

Security patch is a fix to a program to close a known security holes.

Patches are routinely issued for operating system (like windows 7) and internet browsers (like internet explorer, Firefox etc) as well as other applications.

How does virus replicates?

Most of the viruses out there requires a human intervention to start replicating.

You may inadvertently trigger a virus by clicking on an email attachment and once activated it will start creating and distributing copies of itself through email or other programs.

  • Make sure you install patches to all the software you use, this includes browser and other utility programs.
  • Download software only from the first-party website, never you click links on pop-up windows.
  • Be very careful about any free downloads. Remember that malware often masquerades as freeware.
  • Be wary of emails from people you don’t know. Never you open attachment to email of unknown origin.
  • Also be wary of emails from people you know. Some attacks appear to come from someone you know, think twice before opening attachments you are not expecting from your friends try to verify first.

In conclusion, one should always be concious of the cyber security threats available on the internet.

Once you hear about computer and internet, think of security.

Some of the malware writers, write for the challenge or to be famous.

while others write to steal intellectual properties, destroy corporate data, promote fraudulent activity, spy on other countries, creates networks of compromised systems, and so on. This is why you shouldn’t joke with cyber security.

Surf safely always..
