can i remove these files because they asking these file generating spams. I am using OJS version: 3.1.1.4
These files are not related to OJS.
Thanks @NateWr please guide that i delete complete indicated folders or only files because folders have other files as well?
None of the files or folders shown in your screenshot are related to OJS. I can’t advise you on what to delete or not to delete. I can only tell you that those files and folders are not related to OJS.
@hussainyousaf I would suggest to check your settings in regards to security concerns. If public_html is used by your OJS installation, you might want to have a look at documentation on how to secure your system:
https://docs.pkp.sfu.ca/admin-guide/en/securing-your-system
Also keep in mind that if you are running an OJS version that old you might need to apply security patches. The Downloads page has links to the related issues:
https://pkp.sfu.ca/ojs/ojs_download/
For the version you mentioned you would need [Security issue #5302 #5871] - Usually somewhere in the issue description you will find information on how to apply the patches.
