Busting 7 of the most common myths about malware

Malicious software, more popularly known as malware, has been a threat for almost as long as personal computers have existed. As malware has become more varied and sophisticated over the years, public understanding of it also evolved, albeit not always for the better. Even today, a lot of myths continue to circulate about malware and lead people to underestimate its dangers.

Here are some of the most common misconceptions about malware:

Myth 1: Malware and viruses are synonymous terms

A computer virus is a self-replicating malicious program that damages the IT systems it infects. Malware, on the other hand, is a broad term that refers to any type of malicious code or software. So while all viruses are malware, not all malware are viruses. Here are some other types of malware:

  • Ransomware encrypts the victim's data until a ransom is paid.
  • Trojan horses look like harmless programs, but are designed to steal data, disrupt IT systems, or spread other malware.
  • Spyware gathers data about the victim to be forwarded to a third party without the user's consent.
  • Fileless malware uses legitimate programs and processes to infect and damage computers.

Myth 2: Malware can physically damage your device

Despite what some popular media might tell you, a malware infection won’t cause your device to explode. Malware can either steal information or disrupt IT systems, not physically damage devices. However, it can indirectly cause physical damage by, for example, causing a power outage that may lead to equipment failure, or by corrupting firmware that requires manual intervention to fix.

Myth 3: Malware is always made by professionals

Anyone with the right skills and motivation can create malware. In fact, the ILOVEYOU virus, dubbed as one of the most destructive malware in history, was made by a nonprofessional. In the past few years, it has also become easier for neophytes to create their own malware using development kits sold online.

Myth 4: Malware is found only on suspicious websites and emails

Malware can be found everywhere, even on legitimate websites and emails. Hackers can exploit vulnerabilities on popular websites to insert malware onto the site, which can then infect visitors' devices.

Malware can be found everywhere, even on legitimate websites and emails.

Although you can minimize your risk of malware infection by not opening emails from unknown sources, this isn't a foolproof method. Hackers are now using sophisticated social engineering techniques to make malware-laden messages look like harmless emails from people the victims know.

Myth 5: Malware cannot infect mobile phones and Macs

All types of devices are vulnerable to malware infection, regardless of the operating system. In the past, malware infections on Macs and mobile phones were less common because these devices had fewer users. But as the number of mobile devices and Macs increased, so did malware targeting these devices.

Myth 6: Malware infections are always apparent

Most malware infections can go undetected for days, weeks, or even months. In fact, many malware infections are only discovered after they've wrought damage to the IT system. While remaining hidden, some malware can spread throughout the victim's network, causing greater destruction and becoming more difficult to remove over time.

Myth 7: You just need either an antivirus program or a firewall

Anti-malware software and firewalls are best used together to maximize your defenses against malware. An anti-malware solution detects and removes malware, while a firewall blocks malicious codes from entering your device or network.
