When people get infected they always wanted to know how they got infected. Maybe they clicked on a unusual link or clicked an ad that says to clean your PC, well don't it will get you into a very sticky situation and it will take hours to get rid of unwanted malware or crummy software that decides to check your PC without asking permission. That's why I always have an up-to-date computer with Malwarebytes Anti-Malware (Premium) to keep my computer in top-notch condition, and you should too!
Using updates can keep your computer clean, make sure to have a Anti-Malware package installed with it so you can get away from unwanted programs, rootkits, trojans and ransomware. Visiting torrent sites have lots of malware and adware for example a game you want has a trojan in it or a Antivirus Package that has being modified might have a rootkit in it, also free software like VLC media player might have that usual webcake malware packed inside of it.
What is a Trojan?
It's a backdoor malware that is designed to provide unauthorized, remote access to someones computer. Trojans do not have the ability to replicate themselves like viruses, however they can lead to installing viruses, because it is controlled by the Trojans creator. The term Trojan came from a Greek story called the Trojans War, when the Greeks were offering the trojans a peace treaty in the form of a large wooden horse, however once the trojans wheeled the horse behind their closed gates and night fell, the soldiers hidden in the horse climbed out and opened the city gates allowing the Greeks to capture Troy and take over the city. Same as computing using Troy as the computer and the horse as a benign-seeming application. Trojans can cause havoc they steal credit card information and install nasty malware that makes your computer very slow, also the creator can turn your PC into a botnet zombie which can cause more chaos!.
What is a Virus?
A computer virus is a sort of code that is able to multiply itself into large amount of numbers it can corrupt, slow and wreck your computer. It can also corrupt your favourite photos, music and videos so then you'll have to start from scratch thats why you should have a clean backup and make sure you have system restore turned off, because it will backup the malware for you. Virus writers also find exploits in applications so that they can infect your computer.
What is an unwanted application? (PUP)
A potentially unwanted program (PUP) is an annoying program like a cleaner or virus scanner that looks unfamiliar to you. Unwanted programs may have that buy now button which might have a Trojan or virus hidden deeply inside the program. Those programs also have trojans hidden inside the uninstall program when you go and get rid of it which can be rather scary if you don't know what you are doing.
What is ransomware?
Ransomware can lock your computer and hold your precious files hostage. They can also lock it so that you can't look at its contents of the file. Ransomware can also ask you to pay in Bitcoins to unlock your computer which in a way I could say don't. The reason why is because they might be tricking you into a scam, also they might not send the decryption key to your email even though you've paid it. Ransomware also has a timer that counts down to zero, after it reaches zero your files will disappear which can make you go nuclear if you don't have a backup device like a portable hard drive or USB stick.
What is a Rootkit?
Rootkits are another thing I want to talk about. Rootkits can hook deep into a computers system which can make your computer go haywire. Your system might start begin to slow a lot and bootup times will start to degrade. That's why a rootkit removal kit should be handy in case of emergency like TDSS killer provided by Kaspersky which only takes a few moments to scan your computer.
