Cyber threats are extremely frequent nowadays. According to a study by the University of Maryland, an average of one cyber attack occurs every 39 seconds all over the world. Hackers act in various ways: install malware on your personal computer, perform DDoS (Distributed Denial of Service) attacks on websites, steal personal information from protected servers. Hackers are able to infect sites, plugins, and emails with malicious logic. Frauds are able to set up “back doors” and use your system in their machinations. Back doors are hard to detect and overcome. Another great threat is a “botnet”. It’s a large collection of infected machines (up to thousands of computers) that are controlled remotely. Hackers often use them for DDoS attacks and to create security breaches for further malicious intrusions. It’s impossible to protect against all digital threats at once.

Gladly, antivirus software can protect your personal devices from most malicious actions. This software must be chosen properly – it’s the “shield” of your system. Let’s take a look at 5 key criteria you need to consider while choosing antivirus software.

Performance Impact

Some antiviruses are really “heavy” regarding the device resources. When they scan a computer or smartphone for malware, they can seriously impact the performance and slow down the entire device. Usually, all major comprehensive software act this way. Complex scanning has its price. If performance is critical to you, consider using a more lightweight option with less functionality.


Check if the antivirus solution has all the must-have features. Excellent software implements protection from malware, viruses, keyloggers, infected attachments or archives, etc. Some products could secure personal information and banking credentials, scan visited websites for malicious logic, and check your network for suspicious traffic.

The best antivirus software follows the idea “The More, The Better”. Digital protection is the area where security breaches could be deadly.

The Cost of The Product

It’s a common myth that good antivirus software needs to be paid. This statement is only partially true. That myth was born because paid antiviruses usually provide all-in-one security. For example, they can simultaneously defend your personal computer, provide the safety of transactions, and scan websites your visit for malicious plugins and logic. Paid antiviruses are also able to check the sites’ certificates and monitor all incoming and upcoming traffic on your machine.

Free antiviruses protect your system as good as their paid analogs. The difference is that those solutions are usually aimed at certain purposes, like virus protection or internet security. For example, Comodo Antivirus Software is totally free and grants protection from malware and viruses. On the other hand, Comodo Internet Security protects your actions on the Web. The latter product has both free and paid versions.

Reliability And Reputation

An excellent solution protects the system without causing any internal conflicts with other software. It’s a must for antivirus to continuously update its virus signatures. Another huge advantage is the background scanning. It can be a great idea to choose between proven brands like ESETKaspersky, Avast, etc. These companies develop reliable and comprehensive multi-purpose antivirus software for years.


This criterion covers user-friendliness. Great software must be easy-to-use, implement advanced user support, be convenient to configure and access requested functionality. The GUI (Graphical User Interface) must be easy to navigate through features and understand their roles.

Antivirus software provides a comprehensive protection against the majority of digital threats. These defense systems can protect you from malicious actions, malware, keylogging, traffic interception, etc. Choose between famous brands and pick up free or paid software that meets all your requirements for security measures.
