Keep cybercriminals at bay with antivirus software

The word virus appears to be frightening these days, particularly in light of the COVID-19 pandemic. Viruses, of course, don't just affect humans; they severely impact any internet-connected device, including computers, phones, and tablets. Every day, the AV-Test Institute registers more than 350,000 new viruses and potentially unwanted programs (PUA).

While mischievous youngsters hack computers for fun, seasoned hackers do so with the intent of exploiting multibillion-dollar organizations, committing fraud, causing widespread harm, or simply enjoying the adrenaline of breaking into a computer. Not having an AV program installed on your computer is like keeping the door of your home open for criminals. Once the criminal is inside your system, he can steal your data or do permanent damage.

Antivirus software is your first and most effective line of defense against cybercrime. An advanced antivirus program will protect your computer from viruses and malware of all types, including ransomware, Trojan horses, spyware, adware, identity theft, and more.

Unlike traditional signature-based antivirus software, the modern programs combine many trustworthy tools to create a multi-faceted defense against malware and other potential cybersecurity threats.

Why are viruses harmful?

When a device catches viruses and is connected to other devices, the viruses get transferred to those devices as well, spreading harmful programs and instructions that infiltrate and destroy operating systems. Attackers also create computer viruses intending to get illegal access to the devices they prey on to monitor and control activity on the computers of their unsuspecting victims. The hackers can simply get access to or destroy their electronics without the permission of the user.

There are several types of dangerous software such as trojans, spyware, worms, adware, ransomware, resident virus, overwrite, multipartite and more. Each virus harms the system differently. The first step to safeguarding your precious data against these threats is installing a good laptop or mobile antivirus software.

How does computer antivirus work?

Originally designed for desktop computers, antivirus software has been developed to accommodate the changing technical demands of devices. Today, there is antivirus for laptops, mobiles, and other portable devices. Antivirus is nothing but a software program designed to protect your devices from any harm.

All kinds of mobile antivirus and computer antivirus protect the devices by deleting problem-makers and suspicious files. An antivirus scans a huge quantity of data such as web pages, local files, and other apps or software that move through various types of networks. Scanning is typically done using two methods:

  • Reactive scanning:

When you try to execute a program or file that has never been run before, the software runs reactive scanning. The scan looks for any similarities to malware that has previously been identified. If any red flags are detected, the application is paused, and the user is notified of a potential threat, along with options for quarantining and dealing with the threat.

If the scan goes without a hitch, the application will open normally. Reactive scanning runs in the background; therefore the user cannot see the process unless the software detects a problem with the application or file.

  • Active scanning:

The software examines new files as well as browsers and web-based activity (usually inbound). This activity helps the software to detect and stop dangerous ActiveX scripts and Java scripts that the system could come across online.

Scanning the entire system is another type of active scanning. These scans check for possible dangers in every file, corner, and shadow of the system. Most antivirus software has the option to schedule full system scans at regular intervals, as well as the ability to manually initiate a full system scan with a single click.

Types of antivirus for PC:

Some of the troublesome entities include apps that slow down a system, unnecessary windows/websites appearing on the screen, and apps that can completely crash an operating system. As technology advances, the severity of these problems has grown, as have the varieties of antivirus. The following three categories can be used to classify this software:

  • Standalone antivirus:

A standalone antivirus is a specialized tool that detects and removes a few kinds of viruses. Users and administrators can also load this virus on a USB stick to conduct an emergency scan of an infected machine. Due to this portable feature, this software is also referred to as portable antivirus. Most portable antivirus, however, cannot offer real-time protection or cannot download new virus definitions every day. Due to this very reason, this software cannot replace internet security suites, which have a range of extra features.

  • Security software suites:

These are more than just antivirus applications and are capable of detecting and removing viruses. Security software suites also fight all other forms of harmful software and offer 24x7 security to complete systems and files. The majority of these software suites have a firewall, anti-spyware, and parental controls. Some suites also incorporate extra features like VPNs, password managers, and even independent antivirus programs.

  • Cloud-based antivirus:

This is a relatively new form of antiviral technology that analyses the users' data on the cloud rather than on your computer, freeing up computational resources and allowing quicker response times. Cloud-based antivirus has two sections:

  • The client, which is installed on the computer and conducts periodic malware and virus scans without taking up too much RAM
  • The web service, which processes the data collected by the client, then inspects if there are any matches in its database of virus and malware

Key features to consider in antivirus software:

When it comes to virus protection, there are several solutions to choose from. Here is a list of key features to consider in an antivirus:

  • Browsing protection against the dangers while surfing the web
  • Social media protection against malicious and phishing links
  • Dependable firewall to prevent attacks from infiltrating the system
  • Parental controls, allowing you to monitor and limit children's access
  • Ensure efficient virus detection and eradication capabilities
  • Should use minimum memory, allowing the machine to run at excellent speed
  • Protection against newly identified threats and update regularly
  • Should have a virus cleaning mode that transfers infections to a secure location before deleting them from the computer
  • Backup options, allowing you to recover data when lost from the local device


Installing good antivirus software is extremely important to save your valuable data from getting hacked or destroyed. Choosing the best antivirus for PCs is critical for ensuring the security and integrity of our systems are not jeopardized. Always go with a subscription-based package from a trustworthy provider since they offer real-time updates that scan the internet for the most recent threats.
