Malware means malicious software. It includes all types of software programs that can harm your PC and similar devices by stealing sensitive data and affecting its functions. Hackers create malware and other types of bugs to fulfill their predetermined objects or disseminate their propaganda through immoral ways. Such infectious programs usually remain hidden somewhere deep inside the PC before making their appearance in the form of corrupted files and unusual poor functioning of the infected device.
Some of the infamous PC malware are Trojans, Worms, Spyware, Virus, Worms, Adware, Ransomware, and Botnets. However, the list is never complete, as hackers keep on adding newer types of viruses and malware every year.
Below is the list of some major types of malware with brief details on how they function.
Ransomware operates very aggressively. If your system is infected with Ransomware, then you can’t use your PC or get access to the files stored therein. Your PC will turn into a black screen with a ransom note asking you to make payment certain sum using Bitcoins or cash via your credit/debit card.
Once you pay the ransom amount, you are likely to get access to the system. However, there’s no guarantee that you will get your data back in decrypted and uncorrupted form. So, you should always keep a backup copy of all your important data in another device for maximum safety.
Viruses usually infect files stored on the PC. Just like the biological viruses that infect our bodies, computer viruses are expert in damaging the PC’s core files and functionalities by corrupting or erasing executable files. Eventually, your system might stop functioning because of a hard drive failure.
Spyware works behind the curtains. Once it secretly gets into the system through the internet, it sends your sensitive data to hackers and cybercriminals for fraudulent purposes and unauthorized activity carried out in your name.
Such data includes personal information, online banking details, credit card data, and other stuff. When hackers get these data, they potentially misuse the same to fulfill their nefarious intent and obnoxious objects.
The primary objective behind adware is to drive unusual heavy traffic to a particular website and generate revenue. These ads can be extremely frustrating as they interfere with your browsing behavior, and often pop up on the screen.
Adware also freezes other apps, which work behind the scene to keep your PC protected and virus-free. Adware makes your system further vulnerable to dangerous malware attacks by compromising your system security and PC’s health.
Computer worms are highly dangerous. If you have 100s of systems interconnected to each other through LAN or Ethernet, these worms can gradually infect all of them one by one.
Initially, they start their secret operation over a single PC. When it’s infected, then these worms start infecting the other connected PCs in the entire network. These worms slow down the PC’s overall performance and internet speed.
Trojans get into the PC by accidental downloads and installation of executable files. Trojans are notorious for creating a backdoor entry to cybercriminals and getting your core files damaged, modified, or corrupted. Trojans are difficult to identify as they often appear to be legitimate.
As a word of caution, you shouldn’t download any executable files from unverified sources to stay protected from Trojans and other malware.
How To Protect Your PC from Malware
The best way to protect your PC is to ignore anything fishy and suspicious. Always stay away from fake profiles, click-bait images, irresistible offers, executable files, and browser extensions. Always download from reliable and verified sources only. Don’t download 100s of files if you won’t use them regularly. The higher the amount of downloaded files on your PC, the higher is the possibility of getting your system infected with virus and malware.
Unfortunately, despite keeping all precautions in place, your PC may still get invaded by malware. Professional hackers are always looking for that single opportunity to intrude into your device and infect the same with malicious codes. You must keep a malware removal tool in your system to stay safe and protected.

An antivirus tool has a built-in mechanism to detect hidden malware and remove them automatically from devices and gadgets. You should regularly scan your smartphone and PCs to protect your device and system from malware vulnerabilities.
Any malware intrusion into your device or PC requires immediate action. Unless you take the stringiest measures, the such programs could badly harm your system and steal sensitive data.
