What is malware?
The word malware is short for “malicious software.” It’s a general term used to describe programs such as a virus, worms, Trojans, that are designed to wreak havoc on your system or get private information like your credit card information.
Virus
Computer viruses wreak havoc on your files. Like a biological virus, a computer virus infects a file and copies itself, spreading from one file to another, and then infecting one PC to another when the files are copied or shared.
Spyware
Spywares steal your information such as bank details, passwords, and any other information the creator wants to extract from your computer.
Trojan horse
Trojan horses are programs that may seem normal but secretly have malicious code that does something else. Trojans are used to create backdoors that allow your PC to be remotely controlled. The main difference between a Trojan horse and virus is that Trojan horses can’t replicate themselves, they must be installed by an unwitting user.
