How Did I Get Malware on My Computer?

Malware is one of the most common security threats facing internet users. While you have undoubtedly heard about the many types of malwares that may infect your devices, there is a chance you still do not understand how they can do this.

The first step to defend yourself and your belongings is to be aware of these threats. The second—and more important—step is understanding how hackers can slip harmful code into your computer systems, smartphones, and tablets.

Let’s go through four of the most popular techniques and approaches employed by hackers to trick internet users into downloading malware and compromising their data and security.

Scam Websites

Most commonly, malware is distributed through fraudulent websites. These websites often pose as legitimate ones and will steal your personal information (e.g., your login credentials, credit-card details, and even your identity). They may also install malware on your device when you visit them. Be aware of the warning signs that a website may be fraudulent. Some common indicators include sketchy web design, poor grammar and spelling, and requests for personal information that seem too good to be true. To be on the safe side, always check to ensure that a website's domain is official by typing it into an internet search engine or checking for the security certification on their URL bar. If you are still not sure whether they are legitimate, then be on the safe side and stay away!

Malicious Email Attachments:

Email is another common way to spread malware. Attackers will often send malicious attachments in email messages to trick their victims into opening them. These attachments may be disguised as important documents (e.g., invoices or purchase orders), and they may be hiding harmful code that will infect your computer as soon as you open them. Be aware of the warning signs that an email attachment may be malicious. Some common indicators include file extensions like .exe, .vbs, or .bat, and incorrect grammar and spelling.

Social-Media Links

Another way that malware can infect your computer is via social-media links sent by friends or family members. These links may direct you to websites that host malware, or they may install harmful code on your device when you click on them. Be aware of the warning signs that a social-media link may be malicious. Some common indicators include shortened URLs, offers for free downloads, and requests for personal information.

USB Flash Drives:

USB flash drives can also be used to spread malware. Attackers will often create fake USB drives that look real and put malware on them. When someone plugs the flash drive into their computer, the malware will automatically install and start running. Be aware of the warning signs that a USB flash drive may be malicious. Common indicators include unfamiliar or suspicious logos, misspelled words, and files with strange extensions.

Of course, the best way to protect yourself from all these attacks is by using an updating antivirus program and staying vigilant about what you click on. Stay safe!
