Cyber threats on the Internet
The most common threats on the Internet include the following:
- Malware: malicious software that is designed to disrupt or damage computer systems. This includes viruses, worms, Trojan horses, ransomware and spyware.
- Phishing: a tactic used by cybercriminals to steal personal information such as usernames, passwords and credit card numbers. This is often done by sending emails or messages that appear to be from a legitimate source, but are in fact designed to deceive the recipient into giving their personal details.
- Hacking: involves gaining unauthorised access to a computer system or network. This can be done by exploiting vulnerabilities in the software or using social engineering tactics to trick users into providing their login credentials.
- Denial of Service (DoS) attacks: are aimed at overwhelming a computer system or network with excessive load, preventing it from functioning properly. This can be achieved by sending a large number of requests to the server or by overwhelming the network with traffic.
- Social engineering: represents the use of psychological manipulation to trick users into giving up their personal information. It can include tactics such as phishing, pretexting and baiting.
- Botnets: is a network of compromised computers that can be used to carry out a variety of malicious activities such as DDoS attacks, sending spam and stealing personal data.
- Insider threats: involve individuals within an organization using their access to confidential information for malicious purposes, such as stealing data or damaging the network.
What is an antivirus definition?
In order to effectively defend against existing threats, we need to install a suitable antivirus software on our device. What is an antivirus meaning, you ask? Antivirus is a type of software that is used to prevent, scan, detect and remove viruses from a computer. Once installed, most antivirus software runs automatically in the background and provides real-time protection against virus attacks.
What is security software?
Security software is any computer program designed to affect information security. It is often used in the context of defending computer systems or data. Security software is designed to protect and secure servers, laptops, mobile devices and networks from unauthorized access, intrusion, viruses and other threats. It can help protect data, users, systems and companies from a wide range of risks.
Antivirus protection
Anti-virus protection helps protect files and hardware from malware such as worms, Trojans and spyware, and may offer additional protection such as customizable firewalls and website blocking.
How antivirus works
Anti-virus software works by regularly scanning your devices for and blocking known viruses, as well as new and emerging malware mutations. If your device becomes infected, antivirus software will help you remove it. These programs use several forms of detection to provide the best possible protection.
Antivirus benefits
The goal of antivirus software is not only to protect the system from security threats and vulnerabilities, but also to provide real-time protection through automatic vulnerability scanning. An antivirus program provides the following benefits:
- Virus and malware protection: the main advantage of antivirus software is protection against malicious viruses such as malware and spyware.
- Protection against spam and pop-ups: one of the most common ways viruses infect and infiltrate your system is through pop-ups and spam-based websites. Antivirus software secures the system by automatically blocking pop-ups and spam originating from malicious websites.
- Real-time protection: antivirus software acts as a real-time shield that scans every incoming file and program. Depending on the settings of the antivirus program, when an infected file or program is detected, it is automatically removed or moved to a quarantine folder for further analysis. The quarantined file is prevented from interacting with the rest of the computer and its programs to mitigate damage.
- Boot-scan command: sophisticated viruses can often duplicate themselves while the system is active. However, an antivirus program can prevent the virus from self-replicating by invoking the boot-scan command. This command shuts down the operating system (OS), restarts the computer, and checks the entire hard drive for viruses and malware. During the scan, the virus is detected and thanks to the deactivation of the operating system, it has no chance to self-replicate.
- Scanning the dark web: data from most data leaks, such as ransomware attacks, often ends up on the dark web. Many antivirus tools can help companies detect whether their sensitive data has been leaked to the dark web or not. For example, if antivirus find an associated email address or account number on the dark web, it can alert the user and update the password to a new and more complex one.
- External device protection: most people regularly connect external devices such as hard drives and USB adapters to their computers. The antivirus software scans all connected devices and peripherals to prevent potential viruses from entering the system through external sources.
- Spam protection: this is basically protection against unwanted messages or unsolicited advertisements.
- Identity theft protection: antivirus can protect your sensitive information from hackers.
- Parental controls: many antivirus providers also offer parents the ability to control their children’s online activity and prevent them from visiting inappropriate websites or downloading harmful content to their devices.
Why antivirus scan failed ?
The role of an antivirus is to protect our devices from malware attacks such as viruses, malware and ransomware. However, what happens when your antivirus program suddenly crashes and says “virus scan failed”? Here’s a look at a few possible causes of this problem and how to treat them.
- Software updates
One of the most common reasons why an antivirus scan can fail is because of out-of-date software versions. Antivirus programs regularly release updates that include new cyber threat definitions and bug fixes. If you don’t update your antivirus program, its ability to detect and remove threats may be limited. The solution is to regularly update the software and its definitions.
- Software conflicts
Another reason could be a conflict between the antivirus and other software installed on your device. Some applications may compete with an antivirus program for access to system resources or may contain elements that are interpreted as threats. In that case, you can try disabling or uninstalling other apps that might be causing the conflict.
- System errors
Some system errors or file corruption may prevent the antivirus program from working properly. In such cases, you may need to use system repair tools or reinstall an antivirus program to fix the problem.
- New threats
Sometimes a new, unknown threat can be the cause of an antivirus scan failure. Antivirus programs rely on their threat definitions to identify and remove threats. If a new threat appears before your antivirus database is updated, your scan may fail. In this case, it is important that you inform the antivirus provider of the problem and request a database update.
Antivirus – best options and criteria for choosing
All of us are looking for the best antivirus to protect our devices, but unfortunately, not all antivirus products provide a reliable and usable solution that provides an adequate level of protection against malware. When evaluated against the following criteria, even the top 10 antivirus solutions on the market can score very differently, so think carefully about your choice.
- Reliability
Even the most thorough antivirus solution can prove completely useless if it conflicts with other software running on your computer. If these conflicts lead to malfunctions or temporary suspension of antivirus protection processes, it can make your device vulnerable to attacks.
- Usability
If the day-to-day use of an antivirus solution requires special skills, it may be impractical for many users. In some cases, if the antivirus software is too complex to run, the user can simply turn it off and remain unprotected.
- Speed and performance
Although you can’t avoid slowing down your system after installing an antivirus, you should at least check and compare how much your chosen antivirus programs will tax the performance of your computer or smartphone.
- Comprehensive protection
An antivirus solution should provide continuous protection for all computer domains, all file types and all network elements that could be subject to attack by a computer virus or other malware.
- Quality of protection
Regardless of whether you need security software for Apple or Windows , each must be able to operate in an aggressive environment that is constantly changing – with new computer viruses, worms, and Trojan horses that can be far more complex than previously known malware and may include new ways to evade the effects of antivirus programs. The quality of protection depends in part on the following:
- the effectiveness of malware detection processes
- frequency and regularity of updates
- the ability to remove infections from your computer
- the effectiveness of providing computer protection – without significantly impacting computer performance
- Affordability
The antivirus should be affordable and the price should match the quality of the service.
- Application intuitiveness
An antivirus program should be easy to use and intuitive – there is technical complexity and technical jargon associated with computer security, but these should not be a barrier for the user.
- How many devices can you use it on
Many households no longer have just one desktop computer and family members often have their own laptops and smartphones or tablets. That’s why antivirus manufacturers offer the option to use it on multiple devices – so you can protect the whole family for just one fee.
- OS compatibility
Today, it is no longer the exception that every device in the home runs a different operating system (e.g. Windows on a laptop, Android on a tablet and iOS on an iPhone). So check in advance which OS the selected antivirus supports. When choosing an antivirus, you can rely on user and discussion forums where users share their real experiences and knowledge, or you can check sites with independent antivirus tests and expert reviews, for example here.

iOS antivirus (antivirus for iPhone)
iPhones are generally considered more secure compared to other types of smartphones due to Apple’s strict security measures and the closed nature of the iOS operating system. However, it is said that every device should have an antivirus installed for its security – is iOS an exception? Partly. Although Apple has designed its iOS system to be relatively untouchable, it’s still possible to get a virus on your iPhone. The most likely way for this to happen is the so-called jailbreak, when you’ll go around operating system restrictions. You can do this to get more control over your device and download any apps or programmes from anywhere on the internet. Basically, it lets you do whatever you want with your iPhone. But when you also allow your device to download apps from unknown sources, you’ve opened up iOS to a wider range of apps, features, and themes, none of which are approved by Apple! This means that without antivirus protection, you’ve just exposed your device to all kinds of attacks. 1. Norton Mobile Security This antivirus was already mentioned above, but it’s not only the best for Android devices, but also for iOS devices, which is why it deserves the top spot on this list. 2. Avira Mobile Security Avira’s Avira Mobile Security Antivirus is a free, all-in-one antivirus that protects you from theft and scammers.
