Let’s quickly refresh our memory. This 60-second video offers a concise overview of the virus, worm and adware Now, let’s dive into these concepts to better understand how they pose risks to our digital security.

Virus

  •  A malware program that spreads by first infecting files or the system areas of a computer or network router’s hard drive and then making copies of itself. Some viruses are harmless, others may damage data files, and may destroy files entirely.

 

  • CK Explanation: Imagine a computer virus like the flu, but for your PC. It spreads through files, corrupting data and systems. These virus sneaks in through executable files, causing chaos to your system!

Worm

  •  Worm: It can spread without human interaction. Worms often spread from computer to computer and take up valuable memory and network bandwidth, which can cause a computer to stop responding. Worms can also allow attackers to gain access to your computer remotely.

 

  • CK Explanation: Worm uses weak spots in networks to spread by themselves. They don’t need to attach to files like viruses do (self-replicated), and they can slow down or mess up systems by using up resources and attacker might access to your computer

Adware

Adware

  •  Worm: It can spread without human interaction. Worms often spread from computer to computer and take up valuable memory and network bandwidth, which can cause a computer to stop responding. Worms can also allow attackers to gain access to your computer remotely.

 

  • CK Explanation: Worm uses weak spots in networks to spread by themselves. They don’t need to attach to files like viruses do (self-replicated), and they can slow down or mess up systems by using up resources and attacker might access to your computer

What are some tips to avoid Malware and lessen their impact?

 

    • Install anti-virus software from a reputable vendor (at your home, probably Windows Defender can be a great choice for a free version). Update it and use it regularly.
    • In addition to scanning for viruses on a regular basis, install an “on access” scanner (included in most anti-virus software packages) and configure it to start each time you start up your computer. This will protect your system by checking for viruses each time you run an executable file.
    • Use a virus scan before opening any new programs or files containing executable code. This includes packaged software that you buy from the store as well as any program you might download from the Internet.
    • If you are a member of an online community or chat room, be very careful about accepting files or clicking links that you find or that people send you within the community.
    • Make sure you back up your data (documents, bookmark files, important email messages, etc.) on disc so that you do not lose valuable work in the event of a virus infection.
