Malicious software — or malware — is talked about when a dangerous software is used to access and infect a computer or network without being detected. A lot of people hear terms like viruses, adware, spyware, ransomware, worms or Trojan horses; these are all different types of malware that can severely damage computers. Cybersecurity companies are constantly on the lookout to find these treacherous codes and put a stop to them before they cause significant damage.

All forms of malware are extremely dangerous once they infiltrate a device, but the way malware functions differ depending on the type of malware. Below is a list of several types of malware and short definitions of how they work.

The above descriptions only summarize some of the key components of what these malicious software programs can do, but they all carry an equal amount of concern if your computer is affected. In addition, there are a few other types of malware that we haven’t discussed — Botnet, Rootkit, Spam, etc.

When malware was first created, it was used as pranks and experiments, but now it is always destructive. Cybersecurity companies use programs to combat these dangerous attacks. If your network or computer is infected by some kind of malware, you should contact a cybersecurity company immediately.

Malware is not the only form of dangerous online attack, there is also spoofing, phishing and other security hackers that might be able to penetrate your computer’s basic line of defense. To detect any threats before they become a problem, contact ICS today.
