Top 3 Tools to Defend Your Network against Computer Worms. – TechGenix
Like biological systems, computer systems are also plagued by various maladies known as malware. Malware is an all-encompassing term that refers to malicious, hostile, and invasive programs aiming to harm computer systems or networks. You have several malware types, each with unique characteristics and a different purpose. Some common types include adware, ransomware, viruses, spyware, and computer worms.
Worms are a destructive form of malware that can infect multiple systems and networks. In this article, I’ll explain what worms are, their types, and how you can prevent them from attacking your system. Let’s begin with a simple definition.
A computer worm is a type of malware that replicates itself. It typically infiltrates systems by exploiting security vulnerabilities, spreading easily without human interference.
Computer worms can slow down your systems by taking up significant bandwidth and other system resources. They’re also dangerous because they can delete or modify your files, inject other malicious software, or steal data. They can even create new vulnerabilities for other attacks. For example, they can install software that allows a cybercriminal to control your computer and its system settings.
On that note, let’s look at the different types of computer worms.
You can classify computer worms based on the method they use spread to other systems. You have 5 types.
Cybercriminals can spread email worms by hijacking your email and sending malicious messages to all contacts. Initially, the attacker sends the worm as an attachment masked as a media file (.mp4 or .avi extensions) or as a text file (.txt extension). Once the file executes, the worm spreads by automatically mailing copies of itself to contacts found on the newly infected system.
Instant messaging worms are similar to email worms, spreading through disguised attachments to deceive you into downloading them. However, these worms utilize an instant messaging service, such as WhatsApp, rather than email contacts.
File-sharing worms propagate via USB and other forms of file transfer. Like email and instant messaging worms, file-sharing worms disguise themselves as media files. In this case, you’d unknowingly download these disguised worm files to your system, resulting in infection when the file executes.
Internet (or network) worms infect unsecured websites and remain active on that website. When you access the website, the worm exploits security vulnerabilities on your computer and immediately copies itself to your device. From there, the worm can spread to other devices on the same LAN connection.
Peer-to-peer (P2P) worms prey on common vulnerabilities among network members. A P2P connection is when multiple computers share files and have common access to devices such as printers. These worms immediately copy themselves to a file-sharing directory on a local machine. When another user on the P2P network searches a file, the worm will direct that user to download a deceptively named copy of itself. This helps it spread to the new machine.
Now that you know all about computer worms and their different types, I’ll talk about how to identify whether a worm has infected your device.
You can identify worms when you monitor these 4 things in your computer.
Worms feed on your system’s processing power, leading to slower speed and general performance issues. Your system bandwidth may become low, programs may initiate or crash unexpectedly, or your computer may often freeze, etc. This indicates a worm is lurking in your computer.
Worms may overwrite, encrypt, or corrupt files. They can also delete files or create new ones. When you continually monitor your file directories, you’d detect these problems.
Worms spread and create new files, and may take up free space on your hard disk. Observe changes in hard drive usage to tell if your system is infected.
Though this isn’t a computer feature, but worms try to spread by sending copies to your email contacts. You most likely have an active worm on your system if you’ve sent emails to multiple contacts you don’t remember initiating.
If you discover a worm infection, the first thing you should do is disconnect your device from the internet. Isolating the device stops the worm from spreading further. This also prevents it from sending critical information back to the attacker. After that, you can use anti-malware software to identify and properly eliminate the computer worm.
Worms can inflict serious damage if you don’t take the necessary precautions. You may lose crucial data in the process, possibly resulting in financial loss. It’s always best to prevent worm attacks to begin with. Let me explain how!
You can take multiple measures to prevent computer worm attacks.
Aside from those ongoing measures, you’ll benefit from investing in top security software to protect your device from worm attacks. In the next section, I’ll go over the top 3 security software solutions in the market.

Worms and viruses are similar, as they both self-replicate rapidly to exploit system weaknesses and cause damage. However, their main difference is in how they self-replicate. Viruses require human interference to spread, propagating when a user inadvertently activates a host file. Meanwhile, once in a system, worms spread independently of the host file and without any human interference.
Worms can exploit vulnerabilities in host security to steal sensitive information or install a back door for remote access to the system. Worms also use large amounts of memory and bandwidth, causing an overload on affected servers, networks, and individual systems. In addition, worms can also overwrite or delete files on a system, causing valuable data loss.
Worms commonly exploit security vulnerabilities to rapidly infect multiple systems on a network. Worms may also spread via emails or instant messages, posing as genuine files and deceiving users into downloading them. When you open the worm file, it automatically installs malicious software and spreads itself to other machines.
You can remove computer worms manually if you find the initial file and other newer files downloaded by the worm. You can also remove them by using anti-malware tools such as KerioControl or McAfee. These solutions will immediately identify the host file and all other processes the worm runs and quarantine or delete them.
The ILOVEYOU worm created by Onel de Guzman, a Filipino college student at the time, is one of the most notorious worms ever created. This worm spread via email across multiple devices in 2000. The worm attack worked by sending a bogus love letter titled “ILOVEYOU,” infecting over 10 million PCs worldwide and resulting in over USD15 million in damages.
