Even if they don’t know it, everyone’s computer is actually exposed to attack. This is because most of the computers today are connected to the internet. The main reason why malwares thrive is because people don’t know that they exist while others underestimate the effect of these malwares. If you don’t want to deal with problems later on, you need to know the different types of malwares.
The first type of malware is a worm. It is actually a virus that duplicates inside a network. Usually worms are sent to the address book and send one to your contacts that are in the address book. Worse, it disguises itself as a valid message coming from you so your contact will open it. Worms are mediums to send download viruses to your contact’s computer.
Trojan horse is another type of malware. It is actually a program that presents itself as a valid program. There are some cases that the program will have an actual function but it has other evil function. Trojan can delete files including system files, disables security features and infect your computer. Trojans could be the culprit of porn pop-ups every time you open a browser.
Of course everyone knows the virus. Just like the actual human virus, it infects the computer and tries to take control of some of the computer functions. They can be programmed to destroy vital date, retrieve passwords and credit card data and send it to the source. Those who created the virus can use the data for personal abuse.
