In our previous article we read about Email Phishing. Here we will brief about What is Malware and how it affects your computer/host system.

What is Malware?

Malware is software or code written specifically to harm and infect the computer systems. Often people term it as a computer virus but a virus is just one type of malware. As per Kaspersky, Malware, short for “malicious software,” refers to a type of computer program designed to infect a legitimate user’s computer and inflict harm on it in multiple ways. Malware can infect computers and devices in several ways and comes in a number of forms, just a few of which include viruses, worms, Trojans, spyware, adware and more.

How does it affect?

Malware cannot damage the physical hardware of systems and network equipment. But it can damage the data and software residing on the equipment. We should not be confused here with defective software as malware, which is intended for legitimate purposes but has errors or bugs.

How does it infect your computer?

Hackers, malware writers use a variety of methods, sophisticated techniques and malware vectors to spread their malicious programs. They rely heavily on social engineering in order to infect computers. Email Phishing is used by attackers in an attempt to trick the user into opening the email and clicking on links within it or opening a malicious email attachment. Attackers use exploit packs in order to craft Web pages to exploit vulnerabilities in system and application software and spread the threat in drive-by downloads.

Rogue security programs are one of the most common way of malware infection. They infect machines by using social engineering and scams to trick a user into spending money to buy a an application. This application claims to remove malware but actually they trap you. They typically use bogus warning messages and alerts to indicate that your computer is infected with spyware. Alerts may say critical errors as a scare tactic to scare or annoy you into downloading a malicious security application to fix it. These alerts can mimic system messages so they appear   Operating System alerts. Malware writers use the names of well known security tools and legitimate anti-virus programs as part of the name for bogus and fake software in order to trick people into using them.


The longer malware remains on a computer, the more opportunity it has to download additional malicious files. It may install malicious extensions for Internet browsers which can worsen the infection. We should try to get rid of these as soon as possible. We will cover this in upcoming articles.
