Hello,

It's very possible the alerts in the output you provided are false positives, however it's difficult to provide specific security advice without access to the affected system. Have you reviewed the files listed in your output to see if anything within the files look suspicious? You can find a list of qualified system administrators on the following URL if you'd like help with a full security scan of your system:

Thank you.

I agree with Michael, most likely these are false positives. Unless you have other reason to believe the system is compromised you are likely OK, but if you have doubts then you should have a sysadmin poke around.
