The different types of malware

Malware exists in different forms, each of which has its specificity, but which have in common that they are malicious, here are some kinds of malicious applications that you may encounter on the net:


There is a wide variety of malware that can harm your system, such as the trojan. Trojans are designed to discreetly take control of a device from a distance. In order to deceive the user, it is in the form of a reliable program (to avoid its detection), but it actually contains a hidden spy or virus, which can be included in this list.


Spyware is another well-known malware. The spyware is developed to monitor users’ internet browsing. Once the program is discreetly installed on the device, it collects data from the device and transfers it to other people who use it for questionable or lucrative purposes. Websites consulted, purchases made, written or read emails, known internet contacts… it sees everything that is going on in your browser and monitors your activity on the internet!


Adware is a malicious advertising program that is often installed while surfing on the web . Its goal ? Display advertisements without your knowledge. They are particularly tough to avoid (even when using an ad blocker program) and uninstall, and can slow down your PC considerably. But anti-adware like the highly efficient free software ZHPCleaner or AdwCleaner can help you get rid of it.

Similarly, the keylogger copies and steals your passwords, whether it’s your email or your PayPal account …


The computer virus is a very common and famous malware. It is a standalone, “contagious” program that spreads itself from computer to computer and causes serious damage to your files and even your computer system. The virus can blocks functions, destroys programs, clogs the internet connection and can send itself to your entire mail contact list!


The worms is very close to the virus. It spreads over the computer network through technical flaws, without needing to be downloaded or a hacker to run it.


The ransomware ransoms you: this program blocks files or a part of your system and refuses to give you access to them. The hacker asks you for money (a ransom often paid in cryptocurrency like bitcoin or ethereum) to unlock access … not sure that he will finally give it back to you, even if you pay!
