Probable rootkit activity - "AppInit_Dlls". in Malwarebytes Anti-Rootkit BETA Support Posted February 12, 2019 Just a quick update (I hope bumping is allowed on this forum) - I've unistalled Google Desktop Search. I realize it's not a malicious program, but I haven't used it a long a while. Malwarebytes Anti-Rootkit BETA is no longer showing the warning message, so it was indeed the thing responsible for that AppInit value. Huge thanks to exile360, again. I believe the thread can be closed now, if necessary.
