How Does A PC Get Viruses?

There are various ways that your computer gets viruses. One of the most common gateways for malware entering your system is downloading and installing infected software or files from unknown or unofficial resources. Visiting scam websites, pirated media, free games and connecting to the infected external drives infects your device with the malware. Here are some common mistakes that you make that provide safe passage for malicious programs to get on your PC:

  • Downloading infected files from unknown internet resources. It can include files, email attachments and files shared on peer-to-peer networks.
  • Opening malware-attached emails on your PC that you receive from unknown and suspicious resources. These are phishing emails sent by cybercriminals.
  • Getting infected software or apps from unofficial websites and open-source platforms sends malicious codes to your computer that spread to the entire operating system.
  • Using out-of-date web browsers paves the way for malware to automatically down malware and viruses on your system without your knowledge or consent.
  • Falling prey to fake antivirus alerts, updates and misleading pop-up messages. These are part of social engineering techniques that criminals use to deceive you.
  • Using outdated operating programs with security vulnerabilities makes it possible for the virus to break into your system through small vents.
  • Clicking on malicious advertisements or adware linked to legitimate websites leads you to malware that infects your PC with malicious software.
  • Clicking on the links you receive through social media and messaging enables viruses to enter your computer through illegitimate downloads from the attached links.
  • Sharing files over a peer-to-peer network without using a properly integrated network firewall enables the virus to sneak into your computer.
