If you aren’t an IT expert, it can be intimidating hear about all the different types of threats that exist out there on the internet. As a service provider, we see it as part of our responsibility to educate people out there who don’t have a definitive grasp of the technological hurdles that they are facing. There are multiple types of malware, and they all function differently. They have different abilities and take advantage of your operating systems in different ways. In this blog, we will discuss a selection of malware, what they do, and some of the precautions you can take against them.
What Are Computer Viruses?
A computer virus is the term that is tossed around the most as a catch-all term for many different things that infect a computer. A virus infects your systems by attaching itself to a file or program so it can tag along as it travels from one computer to another. As it travels, it leaves infection in its wake. In the same way that viruses can affect humans, the severity of one virus can vary wildly from another.
One virus might cause some irritating operational side effects while another could delete or wholly overwrite other files and programs. A unique trait of viruses is that it requires interaction from you to keep spreading. It travels through email attachments and file transfers. It is typically shared by innocent mistake, but still could have severe consequences.
So What Is A Computer Worm?
A computer worm is actually a sub-class of a virus. They share certain traits, but also have some different features. Worms will also jump from computer to computer, but unfortunately they do not require any help from a person to make the journey. The worms will take advantage of the mass transit systems that are already available within your computer systems to distribute itself. This malicious code will also replicate itself and could send out thousands of copies in all different directions.
Its’ ability to travel on its own power and then replicate itself makes these a uniquely hardy threat. The piece of malware will jump to everyone in your email address book and then to all the people in those email address books, and on down the line. If you do that math, you won’t like the result. Some worms will only cause minor issues, while others could cause DDoS attacks by overloading network bandwidth or system memory with so many demands that you are unable to access your own services.
I’ve Heard Of The Old Wooden Trojan Horse; Is This Malware Like That?
It is exactly like that relic of the Trojan War. It is a destructive program that is disguised as a genuine, trustworthy application. It wants the Greek soldiers to open the gates and download the files. They differ from viruses in that they are not able to self-replicate, but they can still be very dangerous. They will often leave open a backdoor for a hacker to gain unfettered access to your systems. This can allow for the theft of sensitive or personal information. Trojan horses can also just sit there deleting files and destroying valuable data before you can secure it.
