Antivirus software is a critical component in modern device security. Whether it is a PC, tablet or mobile phone, the risk of losing critical data such as banking credentials or other personal information to hackers is real. Malware on your device can corrupt data and render your system unusable.
Your first line of defense is an up-to-date, functional antivirus software that can detect and stop every kind of threat to protect the integrity of your device and secure your data.
An antivirus is a software program that is installed on a computer or any other device to detect, prevent and remove threats. The potent threats inherent on computer systems are known as malware. These could be in the form of viruses, trojans, worms or ransomware.
Generally, viruses are programs that execute malicious activities on your device including but not limited to damaging your system, stealing data and monitoring your activities.
Anti-virus software works by creating a buffer that prevents these threats from penetrating your device or neutralizing them if they are already present. This happens in two major ways:
First, the antivirus program contains a collection of profiles of known viruses. When it scans a file, a reference is made to this collection and if there is a match, the file is either repaired, deleted or quarantined.
Secondly, this utility program works by monitoring any suspicious activity within a device. A program can be flagged by an antivirus if, for example, it tries to change settings or attempts to install an executable file. The antivirus will therefore act immediately to disable the suspicious program.
Antivirus programs are equipped with an auto-update feature that enables them to download new virus profiles regularly to counter evolving threats.
An antivirus software is an important security component for staying safe while using your computer or any other device, whether it is connected to the internet or not – threats can find their way into your computer through the internet or when an external device such as a USB drive is plugged in.
The ever-present threat of cyber crime calls for vigilance to safeguard data on computer systems, smartphones and other devices. An antivirus is actually your first line of defence for emerging threats to your computer system because it will:
Hackers are people who look out for vulnerabilities in your computer system and use them to gain access. They can steal your personal information such as bank account and credit card details leading to identity theft and bank fraud.
They can also install ransomware on your computer, lock it down, denying you access until you pay the ransom. Hackers can also install spyware such as keyloggers (can be used to steal your passwords) or other programs that can use your webcam to monitor your activities.
The antivirus software is capable of detecting such tools used by hackers and block them from penetrating your computer system.
An antivirus program will disable the viruses by disinfecting the bits of data affected and restoring the original data which would otherwise be lost. Viruses can corrupt files and completely damage your computer. The antivirus software protects your system and the data from such an eventuality.
Hackers are finding new ways to infiltrate computer systems and other devices. An updated antivirus software will protect against viruses, phishing scams, ransomware and all other types of emerging threats.
A good antivirus will detect threats and neutralize them before they reach your system. If they do reach your system, the program will work to delete, quarantine or disinfect the offending file or program.
Some antivirus software may detect and destroy a particular malware while others may not. The capabilities of such programs vary and your choice should be guided by the ability to to thwart threats before they cause any damage.
Consider the following factors when choosing an antivirus program:
