No one enjoys being sick. When you’re suffering from a cold, there’s no way you can operate at 100%
It might sound silly, but your computer can catch a cold just like you. OK, maybe not exactly like you—you won’t give your computer a virus by sneezing on your keyboard, but there are similarities.
Computer viruses have the “virus” name because they resemble illnesses in the way they infect a system. Doctors can usually diagnose a virus based on symptoms exhibited by the body. IT professionals can do the same with computers. Typical signs of computer virus infections include:
- Ongoing crashes and blue screen errors
- Slow performance
- Missing files
- Low storage
- Unexpected behavior
- Constant browser pop-ups
- Unidentifiable programs
- Increased network activity
- Disabled security software
How Do You Catch Computer Viruses?
Most people know how to prepare for cold and flu season: wash your hands, cover your mouth when you cough, cover your nose when you sneeze, get plenty of rest, and avoid people who might be sick. It’s something we learn from a young age.
We know to take these precautions, because we know how humans contract viruses. In the same vein, when you know how viruses infect computers, you can take better preventative measures to prevent viruses and identify a virus before it rages out of control.
Here, we illustrate how you can recognize nine common computer viruses.
Common Types of Computer Viruses
1. Resident Virus
Resident viruses set up shop in your RAM and meddle with your system operations. They’re so sneaky that they can even attach themselves to your anti-virus software files.
2. Multipartite Virus
This virus infects the entire system. Multipartite viruses spread by performing unauthorized actions on your operating system, folders, and programs.
3. Direct Action
This virus targets a specific file type, most commonly executable files (.exe), by replicating and infecting files. Due to its targeted nature, this virus type is one of the easier ones to detect and remove.
4. Browser Hijacker
Easily detected, this virus type infects your browser and redirects you to malicious websites.
5. Overwrite Virus
Like the name implies, overwrite viruses overwrite file content to infect entire folders, files, and programs.
6. Web Scripting Virus
This sneaky virus disguises itself in the coding of links, ads, images, videos, and site code. It can infect systems when users download malicious files or visit malicious websites.
7. File Infector
By targeting executable files (.exe), file infector viruses slow down programs and damage system files when a user runs them.
8. Network Virus
Network viruses travel through network connections and replicate themselves through shared resources.
9. Boot Sector Virus
One of the easier viruses to avoid, this virus hides out in a file on a USB drive or email attachment. When activated, it can infect the system’s master boot record to damage the system.
