Pay attention to computer security, take you to recognize several symptoms of the virus

In the process of using the computer, the most worrying about us is computer poisoning. Nowadays, the virus is raging, and once the computer is infected with the virus, it will damage our system. We are always wary of the demon of the virus, then, while watching out, we must also recognize the nature and symptoms of the virus, what are the symptoms of the virus?

1. If your computer is usually very easy to run, But suddenly it became dull or slow, and there was a blue screen or even a crash. At this time, it may be computer poisoning.

2. The running time of the program is lengthened. Some viruses can control the startup of a program or system. When the system first starts up or an application is loaded, the viruses will perform their actions, so it takes more time to load the program.

3. The size of the executable file has changed. Under normal circumstances, these programs should maintain a fixed size, but some viruses will increase the size of the program files.

4. For the same simple job, the disk takes much longer to complete. For example, a text that originally stored a page would take only one second, but an infected virus might take more time to find uninfected files.

5. There is no access to the disk, but the disk indicator is always on. The indicator light of the hard disk is always on for no reason, meaning that the computer may be infected with a virus.

6. Unfamiliar sounds, pictures or prompts, and unusual error messages or garbled characters appear after booting. Especially when this information appears frequently, it indicates that your system may have been poisoned.

7. The capacity of the system memory or hard disk suddenly decreases drastically. Some viruses consume considerable memory or hard disk capacity. Programs that have been executed, when executed again, suddenly tell you that there is not enough memory available, or the hard disk space is unexpectedly small.

8. The file name, extension, date, attributes, etc. have been changed.

9. The contents of the file are changed or some strange information is added.

10. The file disappears bizarrely.

The above are the ten symptoms that will be encountered when the virus invades. By recognizing the manifestation of the virus, we can save the computer in time and maintain the security of the system.
