Malware Detection – A Simple Guide In 3 Easy Points


You must have often heard of viruses attacking your computer or laptop through unknown files, public internet or unsafe websites. Computers need to be protected from viruses or malware as they can access your personal information by hacking into your systems.

1) What is malware detection?

Malware detection serves as an early warning signal for your pc and informs you if you are on a secure platform. Malware detection keeps hackers away from your computer and also prevent personal information from getting leaked. It is important to know what malware is before learning how to detect malware. Read on to explore what is malware detection, its techniques, and how malware detection works. 

Malware is a harmful and dangerous software that can cause harm to your computer pretending to be a legitimate program. There are many different ways by which malware attacks your computer. It can happen anytime and not on a particular day or season. However, it can be installed in different ways malware attacks a device mainly through the fake installer, emails, unsecured links and public internets.

Hackers make users install malware by making it presentable. The users are often unaware that a certain file has a virus attached to it and they download the file innocently. Once the malware is installed, it hides in different folders not being visible to the users. An advanced type of malware can directly access the operating system and hack your personal information. Hence to detect malware and remove it, the process of malware detection is followed. Now let us learn what malware detection is.

Malware detection is simply the process of scanning the files and documents in the computer to detect where the malware is hiding. It involves multiple malware detection tools and approaches. Malware detection takes very less time to detect malware. 

2) How does malware detection work?

There are various steps to how malware detection works. Let’s focus on each one closely:

  • Signature-based detection: This method uses several virus-codes to detect and identify malware. Every malware that hacks into the computer carries a unique code attached to it. When a malware infused file reaches the computer, the malware scanner has the job of collecting the code. The code is then sent to a cloud-based database. The cloud database contains numerous virus code collections. If the same malware code is found in the database, the database lays down a verdict. The antimalware or anti-virus then denies the file and removes it.
  • Heuristic analysis: Heuristic analysis works completely different from signature-based detection. It focuses on putting some restriction on the files being downloaded to prevent malware attack from the beginning. It has certain recognized rules which the files are not allowed to violate. Examples of such rules are that camera manipulation is prohibited, and direct access to hard drive is not allowed. One of the additional pros of this system is that a numerical value is assigned, determining if the file is a threat to the system. The file is flagged as a threat if the score matches the assigned point.
  • Sandbox: The computer has a protected within itself called a sandbox. This is created by the antimalware to keep a check on all files and documents. This helps prevent malware attack because the file cannot attack other files in the computer, allowing it to run smoothly. Sandbox examines and observes the file further to determine if it is induced with any malware. If the file is malicious, it is denied, but it is released if it proves to be clean. 
  • Removal tools: And finally, we come to this very common method of malware detection, which is using removal tools. Once the threat is identified, it must be removed from the system to avoid harm. The removal tools help to eliminate and delete the virus immediately. Once the malware is removed, the files and documents are perfectly secure. 

3) Anti-Malware Software

Anti-Malware or anti-virus software is used for detecting malware. The software is mainly designed for fighting malware on the computer. The software also ensures that the computer is malware-free by regular scans. A computer which does not have an antimalware software downloaded is more vulnerable to malware attacks. Hackers mainly target computers which are easy to get into and have a low-security system.

Once the malware gets pasts the security system on the computer, it proves to be very dangerous. Nowadays, the computer must possess a highly secure and efficient security system to avoid getting hacked into or attacked by malware. Malware is very easily transferred through the internet. When you start surfing the World Wide Web, you are putting your computer into the risk of getting attacked by malware. However, much anti-malware software’s have come up to keep your computer safe and secure. All you need to do is install one and run it.


After reading the above blog, we hope you have understood malware detection and its removal, malware detection methods and malware detection tools.
