A computer virus refers to a malicious piece of computer code spreading from one device to another. These are self-copying threats that can damage a device or steal data. For example, the “Michelangelo” was a computer virus first discovered in Australia in 1991. This virus prevents the computer from booting. It would remain inactive until 6th March every year and then attack the storage devices by overwriting the first one hundred sectors with zero. Therefore, people affected by computer viruses have to contact IT service providers to get solutions. If you live in Brisbane, you can find the best IT solutions in Brisbane by contacting a professional company that can deal with the virus you are facing.
Although you can contact a professional to solve your problem, knowing the different types of computer viruses is essential. This may help you know the nature of viruses and take immediate measures to remove them.
Different Computer Viruses
Attacks attempted by the different viruses are categorised by how they affect or damage your device. You will find subgroups within each classification, as cybercriminals often modify viruses to avoid detection and tracking by an antivirus. These computer viruses can affect computers and mobile devices, and we can classify them into the following different types:
Adware
Adware is a software offering misleading advertising. These ads can suddenly appear in the browser with pop-ups or windows showing the audio-visual content. These ads are played automatically to generate financial gain for the virus creators.
Spyware
Spyware is another virus collecting information from a computer, such as browsing history, sensitive data, etc. Keyloggers are an example of this virus that monitors and tracks all your keyboard activity. This information is then delivered to the cybercriminal.
Malware
Cybercriminals design malware in the form of codes to alter your computer’s normal functioning. And it is without your (user) consent. These viruses can destroy the hard drive by damaging your files. You can detect this virus when you face a sudden slowdown, or your system won’t shut down or restart. Another major indication is that inappropriate ads are automatically played.
Ransomware
Cybercriminals can lock your device with a message requesting a ransom to free it. It is thus called a ransomware virus. Ultimately, the user has to pay the said ransom in digital currency like Bitcoin. Cybercriminals take this approach so that they are not traced.
Worms
These viruses are designed with the capacity to replicate in your system. The effect is that your computer could send hundreds or thousands of copies of itself. It can create an overwhelming devastating effect.
Trojan
The trojan is also malicious code, and it looks legitimate, but it does not. The primary purpose of this virus is to take control of your computer. So, it can damage or disrupt your system, and you can lose your data. Generally, it can also do other detrimental actions on your data or network.
Malicious Apps
When you install an app on your mobile device, it asks you to permit it. At times, these permissions are not associated with the app’s functionality. It is also possible that you download an unreliable app that infects the device by taking control and stealing the information stored in it.
