Viruses Still Exist and They May Be Living Inside Your Computer

Despite appearances that viruses aren’t as common as they once were, these threats are moving in the internet more dangerously than at any time. From ransomware to phishing attacks, everyone can be a target.

The question is, are your protected?

Viruses have significantly advanced. While malware was once limited to annoying pop-ups or slow systems, it has now become much more sophisticated. Various types include ransomware, which restricts access to data; Trojan horses, which disguise harmful files as legitimate ones; adware, which inundates users with incessant advertisements; and spyware, which covertly steals sensitive business information during work. Additionally, phishing scams deceive individuals into providing login credentials, thereby facilitating more severe attacks.

Ransomware attacks often demand hefty payments in exchange for releasing seized data, crippling businesses and individuals alike. One infamous example is the WannaCry ransomware attack in 2017, which impacted hundreds of thousands of computers across numerous countries, causing widespread disruption.

Trojan horses can be particularly deceptive, as they masquerade as useful software while executing malicious activities in the background. A notable instance is the Zeus Trojan, which has been used to steal millions of dollars from online banking accounts over the years.

Adware, though often considered less harmful, can still severely impact user experience by overwhelming systems with intrusive ads that can also serve as gateways for more dangerous malware.

Spyware, like the notorious Pegasus spyware, has been used to infiltrate devices of high-profile targets, leading to significant breaches of privacy and security.

Phishing scams continue to evolve in their sophistication, targeting not only individuals but also large organisations. These scams often employ social engineering tactics to trick people into revealing confidential information, such as passwords or credit card numbers. The devastating 2016 spear-phishing attack on the Democratic National Committee is a prime example, leading to significant political fallout.

The evolution of these cyber threats underscores the importance of robust cybersecurity measures and constant vigilance in protecting sensitive information.

With the increasing dependence on the cloud, work from home, and digital transactions, your data can be at risk if it is not protected in the right way. The good news is you don’t need to be a cybersecurity expert to protect your business.

Here’s how to protect yourself from the most common viruses:

• Ransomware: Backup your files to keep them safe. If, say, you’re attacked by ransomware, you can recover your files without paying the ransom.

• Trojan Horses: Be wary of what you download. Use trustworthy antivirus software that will spot and prevent these clever attacks from entering your system.

• Adware & Spyware: Frequent updates in antivirus software can help to catch these viruses immediately and stay away from clicking on suspicious ads or clicking on unknown links, since they can lead to malware.

• Similar to phishing: Train yourself in recognising phishing emails and avoid downloading attachments or clicking links from unfamiliar sources.

Cyber threats are continuously evolving. As viruses and malware continue to grow, taking simple steps to keep yourself safe can leave a long-term protection. Keeping yourself safe doesn't have to be difficult. Make sure to take necessary precautions to protect your business and your personal information from online attacks.

Stay proactive, stay secure.
