What Is Antimalware?

Antimalware means a software designed to keep your PC safe from malware. It prevents harmful software from infiltrating your computer and compromising data by identifying and removing potential threats.

Regarding PC security, antimalware is the primary defense against malicious software.

Types of Antimalware

After knowing the definition of antimalware, let's dive into its different types. As many types of malware exist in all kinds of shapes and sizes, many antimalware tools are constantly developing to guard your PC from unwanted intruders. Here are some of them.

Antivirus Software

Even though many use the two terms interchangeably, malware and viruses differ.

What viruses mainly do, as opposed to other types of malware, is that they multiply. A virus activates through user interaction with infected files and begins to replicate in other documents and partitions.

Antivirus software aims to identify and remove viruses, often using signature-based malware detection.

Anti-Trojan Software

As the name suggests, Trojans are programs that differ from how they appear. They disguise themselves as something else when they are malicious programs.

Anti-trojan software is specifically designed to target this threat.

Anti-Spyware

Another type of antimalware with a distinct and intuitive name is anti-spyware. Spyware is harmful software that, so to say, "spies" on you. It collects data and information about your digital activity without your awareness or consent.

Anti-spyware aims to identify and remove spyware.

Anti-Ransomware

Unlike the previous antimalware, anti-ransomware tools protect you from a slightly different threat. What does ransomware do exactly?

Ransomware is malicious software that encrypts your files, leaving your data inaccessible. It does so by changing the original file format from readable to inaccessible to anyone but the one performing the encryption.

Anti-ransomware detects these programs and blocks them to the best of its ability.

Firewalls

Although firewalls wouldn't necessarily fall into the category of antimalware, they also perform a critical function.

As the name implies, firewalls are walls or barriers between your PC and programs with unauthorized access trying to invade your digital space. They are network security devices in charge of incoming and outgoing traffic.

How Antimalware Software Works

To better understand antimalware software, it is crucial to know how it works.

Antimalware software must use different techniques to detect and prevent potential threats to your PC. It does so in the following ways.

Heuristics

The word heuristics might sound confusing, but it's simple. Malware heuristics help recognize suspicious behavior of files and programs within your PC.Using its knowledge of malicious programs' and files' behavioral patterns, it detects when something's wrong and alerts you.

Signature-Based Malware Detection

Signature-based malware detection works differently from Heuristics. Every strain of malware is defined through its unique signature. These signatures are collected in databases to which signature-based malware detection software has access.

The software compares programs and files with the database to determine whether or not you are dealing with malicious threats. Although helpful, the downside of this malware detection is that it only deals with known malware and may be unable to recognize new, recently developed harmful software.

Behavior-Based Malware Detection

Contrary to the previous method, behavior-based malware detection follows the behavior of programs and does not scan and compare malware signatures.

It's excellent at identifying new and unknown threats. For instance, if a program tries to modify your system files, this malware detection will find that behavior unusual and label it as a threat to your PC.

Malware Isolation and Sandboxing

Compared to previous detection approaches, isolating and sandboxing is a unique way of protecting your PC.

Sandboxing refers to placing suspicious files in an isolated digital environment, a.k.a. a sandbox. It's like a separate operating system within your system. Isolated from the rest of your files and data, the antimalware can observe the behavior of the program in question within the sandbox. If the program exhibits malicious behavior, it does so in an area where it can't harm your PC, enabling your malware detection software to recognize it as a threat.

Malware Removal

Once it identifies malicious files, your antimalware software takes the necessary steps to prevent the malware from damaging your PC.

It may isolate the infected files from the rest of the system to prevent them from spreading or harming your system further.

It often performs a cleanup, trying to repair the files that malicious software affected. If fixing the infected files isn't possible, the antimalware will likely delete them.

Benefits of Using Antimalware Programs

By now, you probably realize how crucial it is to use adequate antimalware programs. There is no downside to having them, and the benefits are infinite.

Antimalware programs protect your PC from numerous threats, meaning all kinds of malware. Whether it's a typical virus or a Trojan, your antimalware program works hard to protect you from malice attempting to invade your PC.

In addition, it prevents data loss or theft. While you hold some files dear due to personal use and sentiment, other data you possess is crucial for your business or finances. When malware attacks these files, you risk losing so much. That's why having antimalware software to protect your data is paramount.

However, the benefits don't stop there. Antimalware software enables a safe browsing experience, blocking malicious websites and online threats. By isolating malware, antimalware software ensures your PC is up to speed and performing efficiently.

Maybe the most notable benefit of antimalware, at least on a personal level, is the peace of mind it offers. Not having to constantly worry or fear for your digital safety is an undeniable relief, which you can obtain by installing reliable antimalware software.

The Main Features to Look for in Antimalware Software

The primary feature to look for when choosing antimalware software should be its effectiveness in detecting and removing threats.

These are the two critical actions antimalware should perform, and they depend on whether the software has the following:

  • Comprehensive malware protection to defend your system against various kinds of malware;
  • Real-time protection to actively look for malicious files on your PC;
  • Behavioral analysis or heuristics to detect malware focusing on behavioral patterns;
  • Regular updates to keep up to speed with the latest threats;
  • Low false positive rate, meaning it does not falsely flag files as infected or unnecessarily delete them;
  • Automatic isolation and removal, taking action automatically and responding quickly.
