According to the images you posted in the Malwarebytes forum you actually had three detections on 2 around 7:38 PM - two for W32.Extrat and a third for a Packed.Generic.463 detection for a self-extracting compressed executable - see the Symantec write-up at for Packed.Generic.463 as well as the Wikipedia article Executable Compression about these types of compressed executables. I'm not sure how anyone could determine if you had an active RAT running on your computer now that your system has been cleaned, but someone from Norton might be able to provide further insight if the detected files are still sitting in your quarantine folder.

Am I correct that your main concern now is that you've had a malicious remote access tool (RAT) running on your computer that went undetected for several months before you installed Norton? It also looks like you have a Win 10 Pro OS, so if you had an active infection before 2 it would have to be hidden very well if your built-in Windows Defender antivirus and Malwarebytes both missed it. If I understand correctly from that Malwarebytes thread, you just installed Norton this past week and it immediately detected and removed a possible W32.Extrat infection. I found your thread W32.Extrat in the Malwarebtyes forum and it sounds like nasdaq believes your system is now clean, so that's good news. No tool I have run has said I have a RAT running on my system, not that they are fool-proof. I sort of panicked when I saw that file in quarantine, but if my theory above holds, it was never executed. I have run all of my Norton tools, and MalwareBytes Premium, and run through the MalwareBytes forums detection and removal procedures with one of their volunteers (they use bleepingcomputer too).

Programs that infect other programs, files, or areas of a computer by inserting themselves or attaching themselves to that medium. mydocs100114.zip <- Where was this file on my filesystem? Is this a recursive definition? Is mydocs.scr located in mydocs100114.zip located in c:\users\. I would like to know where it is saying this file is, as there is no path: mydocs100114.zip. Below is the result of a quarantine for a remote access trojan.
