Does Antivirus Software Still Work?

Posted August 13, 2019

Antivirus software protects your computer, laptop, or mobile phone from installing malware that can be used by hackers to steal confidential information. Viruses are a type of malware that takes advantage of a program’s vulnerabilities and runs whenever you open the application. Worms are another kind that replicates and attach to other programs. Trojans, on the other hand, appear to be harmless and trick users into running them.

It’s become widely known that visiting unsecured websites, clicking on unknown links, and feeling bad for the plight of a Nigerian Prince can increase your chances of being infected by a computer virus. Most Internet users nowadays are more aware of the dangers of careless web browsing, and a growing number of people think that they don’t need antivirus software anymore. However, you still need this program and the protection it brings.

Here are the reasons why antivirus software is still necessary in this day and age:

1. Additional Layer of Protection

Antivirus software like Scanguard gives you an extra wall of defense against cyberattacks. It continually monitors your system and alerts you when it detects suspicious programs or apps.

Previous versions of antivirus software have received negative feedback because they are worse than viruses in slowing computers down. However, new technology has enabled these programs to run in the background without compromising your experience, thus protecting your PC from automatically installing infected programs in real-time.

These are some instances where you need double protection against malware attacks:

  • Connecting to public Wi-Fi
  • Doing online banking, trading, or shopping
  • Sharing files with others
  • Clicking on web ads and giveaway links
  • Browsing social media
  • Exploring the web
  • Watching adult content
  • Downloading media and documents from the Internet

2. Regular Updates and Upgrades

Hackers are cunning people who continuously create more sophisticated viruses and malware to trick even the most cautious Internet user into clicking and downloading their infected app. They have lots of ways to contaminate your computer with a malicious program. There’s even malware that steals data through power lines.

Developers of antivirus software make it their responsibility to update the vulnerabilities or deficiency in their programs so that they can protect their clients’ computers and information. They are always in the loop with the recent technological advancements, especially concerning data security, and find ways to incorporate these upgrades into their apps.

3. Holistic Approach to Security

While the primary function of antivirus software is to monitor your PC for viruses and malware, most of the programs today offer more features that cover almost all aspects of online security. These apps can also protect you from phishing attacks, spyware, and ransomware, among others.

Some additional features that most antivirus programs offer include:

  • Browser Exploits Defense – Browser exploits pertain to a web code that spots a browser’s vulnerability and abuses it. One example is clickjacking, where a hacker embeds a snippet on a page and uses your mouse to click on a button that you didn’t intend to press.
  • Anti-Rootkit – A rootkit is an infection that goes into your operating system and automatically replaces crucial files with their infected versions. This functionality of antivirus software can hamper the installation of rootkit contamination.
  • Phishing Protection – Phishing is when a cybercriminal contacts you through email, pretending to be a legitimate organization. The objective is to deceive you into sharing personal information, such as your social security number. This feature identifies and alerts you of possible phishing content from your messages or the web pages you visited.
  • Email Guard – Your antivirus software’s email protection function scans inbound and outbound messages for infected attachments and links. Some apps even allow you to quarantine or block malicious programs.

4. Common Sense Can Only Do So Much

It’s tempting to think that you don’t need antivirus software because you have the common sense to be careful about the websites you visit and the files you download from the web. However, cybercriminals are always looking for ways to trick you into sharing your data with them, whether voluntarily or unwillingly. It’s crucial that you are on your guard all the time and add an extra layer of defense against cyberattacks by installing antivirus software.


Some people think that antivirus software are no longer necessary nowadays. While the security of web browsers has definitely improved, antivirus programs still offer additional protection from malware that’s prevalent on the Internet. The codes of these apps are regularly updated to keep up with the sophisticated technology used by hackers and shield your computer from cyberattacks.
