Computer viruses are horrible little programs that are developed to lay waste to your PC. Some terminate files stored on your computer, while some trigger diverse software to malfunction. More immoral viruses steal your private data and some even go to an amount to rig a system’s power load and source it to catch fire. Some horrible little things these viruses are! So, the more you understand about viruses and how they work, the more ready you will find yourself when they come bashing. And with that thought, here are a few computer viruses every computer user should know about.


  1. Resident Virus

A resident virus is different from a non-resident virus in the way it works. A non-resident virus needs to be processed first before it starts its infection. But, a resident virus can start its working whenever the operating system loads. It is capable of doing this because it stores and hides inside the memory of the infected PC, which is why it is tough to get rid of such viruses.

  1. Polymorphic Virus

Horrible is underestimated when we talk about this virus family. When a polymorphic virus hijacks a PC before it begins multiplying it forms copies of itself with every copy a bit different from one another. And as this virus is capable of creating such duplicates regularly, it can be difficult for antivirus programs to find it.

  1. Boot Sector Virus

First, let’s know what is a boot sector – it is a part of a PC’s hard drive or an external storage media. This portion contains data which is needed to boot a system. A boot sector virus harms part of this boot sector called the master boot record (MBR) and alters genuine information with its own infected version. The virus gets triggered before the operating system loads and it may make the infected computer unbootable.

  1. Overwriting Virus

Similar to its name, an overwriting virus deletes the file it infects. It executes this by overwriting data in the device’s memory. The virus can be cleared only by deleting the infected file. Often, cleaning an overwriting virus means losing the infected programs and reinstalling them.

  1. Compound Virus

While other viruses attack one part of a computer at a time, a compound virus attacks two. This virus can infect both the boot sector and the system or program files at the similar time. These start infections at multiple sections in the PC – just like multiple bombs exploding at various places at the same time. Because of this double infection method, the compound virus can re-infect the same PC over and over again until all its workings are completely eliminated.

What we have mentioned here about these PC viruses is just one tiny feature of what they do. Facts on how malware and viruses function might not be simply comprehended by everyday users. But the main thing here is that such malicious programs can modify your digital devices against your expectations.
