Hello,

Yes, You can remove that files from /tmp but first I will suggest you please try to scan your /tmp directory through LMD(Linux Malware Detect) May be that files infected with the malware

Hello

You may be able to determine which user the files are coming from, depending on your PHP handler. If you find they are from a single account, and disk space is a concern, you could have that account configure an alternate tmp location.

Thank you.
