Hello! Today I will discuss malware and spyware.
Malware is short for: Malicious software. The word "malicious" should itself be a warning to you. And should be taken very serious.
Malware has several formats: worms, Trojan horses, root-kits, key-loggers, back-doors.
Worms are basically out to do as much damage to your system as possible. To try and destroy your operating system.
Trojan horses lay dormant: to gather Information from your computer. Like: passwords.
Root-kits embed themselves really deep in your system and are very difficult to remove. In a lot of cases you have to reinstall your operating system.
Key-loggers. A very nasty piece of spyware. They basically remember what you type on your keyboard. For instance: passwords to your accounts.
Backdoors: Another nasty piece of spyware. This is what hackers use, once they get access to your computer. They use this to install other nasty pieces of malware on your system; like the things I've discussed above.
One thing to remember: If you ever get any of these threats; this includes virus threats, which I will discuss in the future. Never reboot your system. This will make the problem worse.
I hope this helps you.
