In the digital world, a virus is malicious software designed to infect computers, smartphones, and other online devices. Like a biological virus, it can spread from one device to another, causing harm and disrupting normal operations.
Hackers can use viruses to gain unauthorized access to computer systems and networks. In fact, every 39 seconds, there is a hacking accident somewhere in the world. Moreover, in the first quarter of 2023, a 7% increase in cyber-attacks happened worldwide.
This rampant cyberhacking strongly suggests the importance of effectively removing computer viruses. This malicious software can wreak havoc on your system and compromise sensitive data.
This article covers how to get rid of a virus on your computer, detect viruses, and use reliable anti-virus software.
Let’s dive in.
A computer virus is a type of malware designed to infect and spread from one computer to another. Viruses can steal personal data, hack social media or online banking accounts, wipe data, or make your computer unusable.
The first known virus was the “Creeper” virus, developed in 1971, which simply displayed a message on infected computers. Since then, viruses have evolved significantly in complexity and severity.
Virus statistics reveal a consistent and concerning trend. Daily, 560,000 new malware pieces are discovered, adding up to over 1 billion.
One of the current trends in viruses is the rise of phishing attacks. Statistics show that in 2022, over 500 million phishing incidents were reported. Cybercriminals have become more skilled at creating deceptive emails, websites, or messages to trick users into disclosing sensitive information.
Here are a few computer viruses that are currently circulating on the internet:
