Why antivirus software is essential

With cyber threats growing in sophistication and frequency, antivirus software is not just an optional extra; it’s a crucial line of defence for computers, phones, tablets, and even smart home devices.

Antivirus software plays a key role in detecting and removing malicious software such as viruses, ransomware, spyware, and trojans. 

These types of malware can steal personal information, corrupt files, slow down device performance, or even render a device unusable. By running real-time scans and monitoring for suspicious behaviour, antivirus programs help prevent these threats from infiltrating your system. 

While most people associate antivirus software with desktop and laptop computers, smartphones and tablets are also being increasingly targeted by cybercriminals. Mobile devices store sensitive data such as banking information, personal photos, and emails, making them attractive targets. 

With the growing number of malicious apps and phishing attacks on mobile platforms, installing reputable antivirus software can provide essential protection against these risks. 

Another key reason to use antivirus protection is the rise of ransomware: a type of malware that locks you out of your device or files until you pay a ransom. These attacks are not limited to businesses; individuals are frequently targeted as well. 

Good antivirus programs can detect and block ransomware before it causes harm, potentially saving users from data loss or financial damage. 

Antivirus software often includes additional features such as firewalls, safe browsing tools, password managers, and anti-phishing protection. These added layers of security enhance your overall digital safety and provide peace of mind while browsing, shopping, or banking online.

It's also important to keep antivirus software up to date. Cyber threats evolve constantly, and updates ensure your device is protected against the latest vulnerabilities. Many antivirus solutions offer automatic updates and scans, making it easy to maintain protection without regular user intervention. In short, antivirus software is not just a luxury; it's a necessity.  

The question arises: which one to choose? 

There are several reputable brands on the market, with competition between them ensuring they are all fit for purpose and up to date. 

Australian PC Magazine has tested a range of software and recently named Bitdefender Antivirus Plus as best overall, with it achieving 4.5 stars out of 5.

It also recommends: 

• McAfee Antivirus, which had the best scores in its lab tests 

• Norton Antivirus Plus, as best for extra security features 

• Malware Bytes, as best for speedy scans 

• Webroot Essentials, for its small footprint (it takes up less memory space on your device than similar software) 

• GData Antivirus, for the “best breadth of features” 

• Avast One Basic, as the best free antivirus software.
