Hi, I have tested it with Process Monitor: it shows that the file to be scanned is not opened by Malwarebyte. The only command that contains this file (CAPTURE88 QVC 2.AVI) is the following: C:\Program Files (x86)\WinRAR\RarExtLoader.exe "C:\Program Files (x86)\WinRAR\RarExtLoader.exe" RarLdrTitle252730480#RarExtMapFile252730480 Date & Time: 10.08.2014 08:58:29 Event Class: File System Operation: QueryOpen Result: SUCCESS Path: M:\Public Videos\CD\CD-R5\CAPTURE88 QVC 2.AVI TID: 5700 Duration: 0.0000118 CreationTime: 08.08.2014 13:21:20 LastAccessTime: 08.08.2014 13:21:20 LastWriteTime: 27.09.2001 13:09:30 ChangeTime: 08.08.2014 13:31:33 AllocationSize: 5.722.112 EndOfFile: 5.722.072 FileAttributes: A I think, malwarebytes should open this file also and there should be an appropriate command. Furthermore, Windows event viewer reports an error: Log Name: Application Source: Application Error Date: 10.08.2014 08:58:48 Event ID: 1000 Task Category: (100) Level: Error Keywords: Classic User: N/A Computer: Wolf-PC Description: Faulting application name: mbam.exe, version: 1.0.0.532, time stamp: 0x53518532 Faulting module name: QtCore4.dll, version: 4.8.4.0, time stamp: 0x51352df8 Exception code: 0xc0000005 Fault offset: 0x001256a3 Faulting process id: 0x4fc Faulting application start time: 0x01cfb46882331499 Faulting application path: C:\Program Files (x86)\Malwarebytes Anti-Malware\mbam.exe Faulting module path: C:\Program Files (x86)\Malwarebytes Anti-Malware\QtCore4.dll Report Id: c66a95a8-205b-11e4-9bae-50465d082d91 Event Xml: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Application Error" /> <EventID Qualifiers="0">1000</EventID> <Level>2</Level> <Task>100</Task> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2014-08-10T06:58:48.000000000Z" /> <EventRecordID>25325</EventRecordID> <Channel>Application</Channel> <Computer>Wolf-PC</Computer> <Security /> </System> <EventData> <Data>mbam.exe</Data> <Data>1.0.0.532</Data> <Data>53518532</Data> <Data>QtCore4.dll</Data> <Data>4.8.4.0</Data> <Data>51352df8</Data> <Data>c0000005</Data> <Data>001256a3</Data> <Data>4fc</Data> <Data>01cfb46882331499</Data> <Data>C:\Program Files (x86)\Malwarebytes Anti-Malware\mbam.exe</Data> <Data>C:\Program Files (x86)\Malwarebytes Anti-Malware\QtCore4.dll</Data> <Data>c66a95a8-205b-11e4-9bae-50465d082d91</Data> </EventData> </Event> So, there is probably a bug in Malwarebytes new version. It is too easy to say, the system is infected and the software does not run correctly!!! Where did you locate the infection in my logs posted?
