I suggest you kill virus in safe mode. If the virus is still the same after killing, I suggest you repartition the hard disk, reinstall the operating system or restore the system.

Main reasons:

1. If the computer system is installed on drive C, the main program file is installed in D:\Program when installing the application.

File, but there are still many running system files (such as registry and some startup files) that will be automatically copied to folders such as C:\Windows\System.

2. The temporary files in the installation process are also on the C drive, and may not be deleted by the software itself. The system will also generate some temporary files and virtual memory files on drive C. ..

3. Some software will be updated automatically. The default installation path of these automatically updated files may be the system disk, and some temporary files will be generated during the software execution. Some software will automatically delete these temporary files when exiting the system disk, but sometimes it is necessary to delete the temporary files manually.

For example, after pplive is installed, a file with the capacity of 1G will be generated on drive C to store the temporarily downloaded files.

Therefore, the capacity of disk C will gradually become smaller.

Solution:

1. As long as there are enough C drives and enough virtual memory space, users don't have to care too much about the above problems, and it won't have much impact on system performance.

Therefore, it is recommended to install the application in the default folder of drive C, so that all space will be released after formatting drive C when reinstalling the system, otherwise the original installation files on drive D need to be deleted manually.

2. It is suggested that the junk files and temporary files in the system should be cleaned regularly, which will help to slim down the system disk.
