Best Anti-Virus Software

Although surfing the web or watching a video can seem harmless, there are dangers to your computer lurking all over the internet. Various types of malicious software, otherwise known as malware, can be used to monitor what you do online and perhaps steal your personal information. The specific types of malware that hackers use change frequently but can include:

  • Viruses, which alter your computer’s software in harmful ways
  • Adware, which causes intrusive ads to appear on your screen
  • Spyware, through which someone can monitor your computing activities
  • Ransomware, which can lock up your computer and render it unusable until you pay a fee, or “ransom”
  • Worms, which are bits of software code that can spread from one computer to another
