Top 10 Free Anti Virus Software in 2022 | #itsecurity | #infosec | #hacking | #aihp

Antivirus protects against various cyber attacks, from malware to online threats. While advanced antivirus can cost a company several hundred dollars annually, some free options are available for office or home use. This article discusses the top 10 free antivirus software in 2022. 

Key Must-Have Features for Antivirus Software

A computer virus refers to malicious code capable of replicating itself, possibly evolving and causing unwanted effects on the computer. It attacks the computer much in the same way that a biological virus will attack the human body. Computer viruses are now grouped under a family called malware which encompasses every other form of malicious programs such as spyware, worms, Trojans, etc. 

Key Must-Have Features for Antivirus Software

Malware typically comprises code created by programmers for criminal reasons like holding organizational data for ransom, stealing financial information, etc. The good news is that there is also computer antivirus software to combat these viruses, and many of these applications are available for free. 

Computer antivirus software is software programs designed to protect a computer system or any other electronic device from the effects of malware. Antivirus can also be seen as a class of computer programs used to scan, prevent, find and eliminate viruses from a machine. Every individual or organization owning computer devices also needs antivirus software. The following key features enable the antivirus software product to protect your systems: 

1. Real-time scanning

Real-time scanning is an essential feature of antivirus software. When scanning, antitrust software searches for any unusual activity or signature. Scans can be automatic and continuous – they occur in real-time. They can also be scheduled or manual. However, real-time scanning is more proactive and protects your computer from perceived threats when surfing the net, downloading files, etc. This makes real-time scanning a huge plus for any antivirus software. 

2. Performance friendliness

The performance friendliness of antivirus software denotes how easy it is for any user to leverage daily. This includes both the simplicity of the user interface (UI) design and, even more important, the ability of the program to run in the background without negatively impacting the system’s performance. Good antivirus software should not take up too much RAM space or slow down the computer during scanning.

3. Automatic updates

Automatic updates are a feature every antivirus software should possess. For an antivirus to be very effective, it must be aware of all the existing viruses and malware making rounds across the internet through regularly updated threat intelligence. This means that it still has to be updated with new information after delivery and installation. When these updates are manual, the user might update the software too late after being exposed to the virus. Automatic updates help to avoid this.

4. Operating system compatibility 

Good antivirus software should be able to run effectively on multiple operating systems. Users often want to leverage one antivirus program across all of their devices. Be it a PC, Macbook, iPhone, or Android device. The best antivirus are those capable of working across the board and remain a preferred option. This feature also reduces the learning curve and effort duplication.
