Know How To Protect Agains Different Types of Malware

What Is Malware Or Malicious Software?

Malware is normally delivered in the form of a link or file over email and requires the recipient to click on the link or open the file to execute the malware. In the technical sense, malware is the collective name for a number of malicious software variants, including viruses, worms, ransomware, and spyware. Shorthand for malicious software, malware typically consists of code developed by cyberattackers, designed to cause extensive damage to data and systems or to gain unauthorized access to a network.

Actually, Malware has been a threat to individuals and organizations since the early 1970s when the Creeper virus first appeared. Since then, the world has been under attack from millions of different types of malware, all with the intent of causing the most disruption and damage as possible.

How Malware Works?

There are many different types of malware that can enter your computer via malicious file downloads, visiting infected websites, or through an email containing seemingly benign link or attachment. A network or device can be attacked and infected by the malware spreaders use a bunch of physical and virtual means to spread malware. For example, A USB drive can spread malicious programs to a system and can be distributed over the internet through drive-by downloads, which automatically download malicious programs to systems without the user’s approval or knowledge.

Phishing attacks are another common type of malware delivery where emails impersonate as legitimate messages include malicious links or contain attachments that can deliver the malware executable to unsuspecting users. Sophisticated malware attacks often feature the use of a command-and-control server that allows threat actors to communicate with the infected systems, exfiltrate sensitive data, and even remotely control the compromised device or server.

How Do You Know That You Are Infected With Malware?

While these types of malware differ greatly in how they spread and infect computers, they all can produce similar symptoms. Computers that are infected with malware can exhibit any of the following symptoms:

  • Increased CPU usage
  • Slow computer or web browser speeds
  • Problems connecting to networks
  • Freezing or crashing
  • Modified or deleted files
  • The appearance of strange files, programs, or desktop icons
  • Programs running, turning off, or reconfiguring themselves (malware will often reconfigure or turn off antivirus and firewall programs)
  • Strange computer behavior
  • Emails/messages being sent automatically and without the user’s knowledge (a friend receives a strange email from you that you did not send)
