Malware vs Virus: Key Differences You Need to Know

In our interconnected digital landscape, Malware vs Viruses are often tossed around, but they’re not quite identical. Here’s the scoop: malware is the umbrella term encompassing various types of malicious software. Viruses, on the other hand, are a specific subset of malware. Imagine malware as a vast ocean, with viruses just one type of fish swimming in those murky waters. Like biological viruses, computer viruses seek to spread and replicate themselves, infecting everything from laptops to servers.

What is Malware? 

Malware refers to any software intentionally created to harm or compromise computer systems, servers, or networks. It comes in various forms, each with its specific purpose and method of attack.  

Different Types of Malware

There are several Types Of Malware, which has evolved with the advent of newer technologies. Here are some of its common types:  

a) Ransomware: This malicious software encrypts files or locks users out of their systems until a ransom is paid. Victims must pay to regain access to their data. 

b) Spyware: Spyware operates covertly, monitoring user activity and collecting sensitive information without the user’s knowledge. It can track browsing habits, keystrokes, and more. 

c) Adware: Adware bombards users with unwanted advertisements. It often redirects browser searches and can be quite annoying. 

d) Trojans: These deceptive programs masquerade as legitimate software but contain hidden malicious code. Once installed, they can compromise system security. 

e) Worms: Worms self-replicate and spread across networks without user intervention. They exploit vulnerabilities to infect other devices. 

f Rootkits: Rootkits embed themselves deeply within an operating system, making them hard to detect. They hide malicious activities and provide unauthorised access to attackers.

What is a Virus? 

A virus is a specific type of malware that attaches itself to clean files, replicates, and spreads across systems. Unlike other malware, viruses require user action to spread, such as opening an infected file or email attachment. Once activated, viruses can corrupt files, steal data, or render systems unusable. 

Different Types of Viruses 

Similar to Malware, Viruses have constantly reshaped itself into newer versions and types. Below mentioned are some of the common types of Viruses:  

a) File Infector Virus: This type of virus attaches itself to executable files (such as .exe files) and spreads when the infected program is run. It modifies the clean file by inserting its own code, which allows it to replicate and infect other files. 

b) Macro Virus: Macro viruses specifically target documents created in applications like Microsoft Word or Excel. They exploit macros (small scripts) within these files to execute malicious actions. Opening an infected document triggers the virus. 

c) Boot Sector Virus: These viruses infect the master boot record (MBR) of a computer’s hard drive. The MBR is essential for booting the operating system. By corrupting it, boot sector viruses can make it challenging to remove them. 

d) Polymorphic Virus: Polymorphic viruses are particularly sneaky. They change their code each time they infect a new file, making detection difficult. Their ability to mutate helps them evade antivirus software. 

e) Multipartite Virus: This type of virus combines features of both file infector and boot sector viruses. It attacks both the boot sector and executable files, causing widespread damage across the system. 

Malware Vs Virus: Key Differences 

While all viruses are malware, not all malware is viruses. The key difference lies in their behaviour: malware is a broad category of malicious software, while a virus specifically refers to malware that self-replicates by modifying other programs. Malware can be designed to carry out various harmful activities, while viruses focus on spreading through infected files and causing damage to systems.

How to Protect Against Malware and Viruses? 

Protecting against malware and viruses goes beyond smarter approaches. It requires a combination of the latest anti-viruses and safe practices. Below we described those methods:  

Use Antivirus and Anti-Malware Programs 

Invest in reputable antivirus and anti-malware software to detect, quarantine, and remove malicious software before it can cause harm. Regularly update these programs to protect against new threats. 

Adopt Safe Online Practices 

Be cautious of unsolicited emails, downloads, and websites. Avoid clicking on suspicious links or attachments. Always verify the source before downloading files or software to minimise the risk of infection. 

Protect Your Network 

Secure your home and office networks with strong passwords and encryption. Use a firewall to monitor and control incoming and outgoing network traffic, reducing the risk of malware or virus attacks. 

Regularly Backup Your Data 

Regular backups ensure that your data is safe even if your system is compromised. Use external drives or cloud services to create copies of important files, allowing for quick recovery in case of a malware or virus attack.
