Why is cyber security important?

Since the advent of the Internet, cybersecurity has always been a debacle. As technology continues to advance, computer viruses are also spreading in different forms.

Bob Thomas developed the first virus known as the ‘creeper’ in 1971. It was not a malicious threat; it only replicated itself from one drive to the next.

After successful installation, it can now reveal its true nature while working in the background. 

How Trojans Work

When you open it, you will find a link that prompts you to click to read more. But, what you don’t know is that cybercriminals are targeting you, and the link is a Trojan malware that has infected your system. 

Once you click and open the file, the malware will automatically download and install itself on your machine. It will then damage files and take over your computer. Since the malware has different functions, it might also compromise bank account information and relay it to hackers or use your data to commit fraud.
