A computer virus is an application that interferes with the performance of a laptop computer or computer. This virus can even damage your computer, laptop, or netbook. Viruses can enter a laptop computer caused by a file switch via a flash drive, application installation, or via the internet. What is attacked by the virus is the operating system, even to hardware damage.
There are many types of viruses, such as Trojans, Worms, Web Scripting Viruses, Multipartite Viruses, FAT Viruses, Companion Viruses, Directory Viruses, Polymorphic Viruses, and so on. Each virus has its own characteristics. For example, how to remove a Trojan virus, how to remove a browser virus, and so on. Because of that, many antiviruses are created as an alternative to exterminating computer viruses. Antivirus also must be updated regularly to be able to scan for viruses that also continue to grow in type.
To find out how the characteristics of a laptop computer affected by a virus and how to check for a virus on a laptop, you can pay attention to the following things:
1. Hard disk free capacity is reduced
When the virus has installed itself on your laptop computer, the virus will automatically take up the free-house capacity on your computer's laptop hard drive. Even the empty capacity of your hard drive can be used up by these viruses.
2. Many of your files are damaged or corrupted
One of the most common consequences of viruses is the destruction of files on the laptop. In addition to installing itself and consuming hard disk space, viruses can enter your files and replace them so that you cannot access the files. If you keep accessing these files, chances are the virus will spread and damage other files.
3. Hard disk becomes corrupt
Not only files that can be corrupted by viruses. Viruses can also cause your hard drive to be corrupted. Hard drives like this are usually marked with a locked hard-drive layout. That way, you automatically can not access your hard drive. If the virus is not removed immediately, then chances are you can lose the hard drive and its contents.
4. Files are lost or hidden
The files are lost, but the hard drive capacity is not reduced. This could be one of the characteristics of your computer infected with a virus. How to check for viruses on your laptop computer can check whether your files are really lost or just hidden. If the capacity of your hard drive is still the same as before, most likely the files have not been deleted from your computer. It's just that you can't access it because it's hidden by itself.
5. Laptop computer performance becomes slow
Laptops are slow or slow for many reasons. If you have a laptop computer that usually has good and fast performance but suddenly slows down, you should immediately be alert. Because this is the characteristics of a laptop computer that is infected with a virus. The slowness of this laptop computer can be because the virus has filled the capacity of your hard drive and the RAM memory of your laptop computer. If the RAM memory is full, your laptop computer will automatically not be as fast as usual.
6. Laptop that restarts itself
An overworked laptop can experience an automatic restart to relieve its workload. A laptop infected with a virus is most likely to experience this because the virus has drained the laptop computer's memory, namely RAM memory and hard disk. In addition to viruses, you must know the cause of the laptop computer restarting itself so you can determine whether it is due to a virus or not.
7. There is an application or software that can't work
Some software on a laptop computer or computer is easy to get viruses. Or maybe there are some viruses that are in charge of destroying certain programs. If the software is damaged, you can reinstall it. But if it is damaged again, then no doubt, there is a virus in your laptop computer.
8. Antivirus suddenly turns off
Viruses attack antivirus? It could happen. This is if your antivirus is very rarely updated. After turning off the antivirus, the virus will attack other files on your laptop computer. Use a top-class antivirus for your laptop computer to prevent this from happening. In addition, be diligent to replace your antivirus.
9. A strange message or notification appears
This usually happens when you turn on your laptop computer, and suddenly an unusual message appears. This message sometimes uses incomprehensible Russian or Chinese. This message will greatly interfere with your activities when using a laptop.
10. There is a strange file in the laptop
This is one of the most common characteristics of a laptop computer infected with a virus. The strange files are in the form of .EXE, .CONF, and so on. If you access this file, the virus will spread directly to your laptop computer.
11. Laptop computer programs run without commands
One of the characteristics of a laptop computer affected by a virus is that some laptop computer software runs alone. You can just uninstall the application, but that does not guarantee that the virus on your laptop computer does not attack other software.
12. Can't enter windows
Viruses that attack the operating system cause you to not be able to enter home windows when turning on the laptop. Since you can't enter windows, you won't be able to check what's happening on your laptop computer. But you can use protected mode for this.
That's all for my discussion, I hope it's useful.
