    Hi, I’m getting this error in the anti malware page.

    “Another Plugin or Theme is using ‘W3TC\Generic_Plugin::ob_callback’ to handle output buffers. 

    This prevents actively outputing the buffer on-the-fly and could severely degrade the performance of this (and many other) Plugins. Consider disabling caching and compression plugins (at least during the scanning process).”

    I do have another plugin called “Antivirus” from pluginkollektiv and added McAffee Secure to the site. I was wondering if disabling those would help but I did and the error kept comming.

    Even in a new installation of WordPress I’m getting that error message. (I got a couple of websites)

    What can i do in this case?

    That error seems to be pointing to W3TC (the caching plugin) have you tried disabling caching and deactivating W3TC?

    There could also possibly be some malicious script that is pretending to be W3TC but it would not be on a fresh new installation of WordPress unless your whole server is compromised. How many sites do you have on this server and are they all installed in subdirectories under a main/parent site?
