Full scans are not really needed on any regular basis and can take an extremely long time.

I will take a look at the log here in a bit and reply more.

Malwarebytes is not designed to function like normal AV scanners and uses a new kind of scan engine that relies mostly on heuristics detection techniques rather than traditional threat signatures.  Malwarebytes is also designed to look in all the locations where malware is known to install itself/hide, so a full or custom scan shouldn't be necessary, especially on any sort of frequent basis (like daily), especially since the default Threat Scan/Quick Scan checks all loading points/startup locations, the registry, all running processes and threads in memory, along with all system folders, program folders and data folders as well as any installed browsers, caches and temp locations.  This also means that if a threat were active from a non-standard location, because Malwarebytes checks all threads and processes in memory, it should still be detected.  The only threat it *might* miss would be a dormant/inactive threat that is not actively running/installed on a secondary drive, however if the threat were executed then Malwarebytes should detect it.  Additionally, whenever a new location is discovered to be used by malware the Malwarebytes Research team adds that location dynamically to the outgoing database updates so the locations that are checked by the default Threat/Quick Scan in Malwarebytes can be changed on the fly by Research without requiring any engine or program version updates/upgrades.

As you are on the free version you have no active protection from Malwarebytes. The real protection comes from the real time protection in the Premium version.

I also see 3 drives on the computer. "IF" you wish a full scan, only do your "C" drive and not he other ones. And do not enable rootkit scan either as that increases the scan time more.

Drive c: () (Fixed) (Total:237.41 GB) (Free:173.46 GB) NTFS
Drive d: (2TB) (Fixed) (Total:1863.01 GB) (Free:1370.23 GB) NTFS ==>[system with boot components (obtained from drive)]
Drive e: (4TB) (Fixed) (Total:3725.9 GB) (Free:409.3 GB) NTFS

I suggest using Windows Defender for the "full" scans since it seems you removed Kaspersky at some time.

Your log shows Malwarebytes was just installed today, Were you just trying to get a second opinion?
