Last week I noticed my C drive had only ~19Gb of free space out of 500Gb, I found that there were hundreds (thousands actually) of MSIxxx.tmp files of 12119kb in size, taking ~290Gb...
I ended up deleting them and nothing wrong happened and C drive was back to normal free space. Today I checked to make sure these files were indeed gone, but I found that they're coming back... There are 11 of these files being created every 15 minutes I've searched around, but did not find anything similar to this...
ESET endpoint AV ver 9.0.2046.0 is installed in my PC and has not reported anything back, I have scanned using free version of Malwarebytes and did not find any issues, this is a screenShot of the 'installer' folder...
So, I'm not sure if this is some sort of bloatware going on or there is something really huge being downloaded for Windows update... any ideas?
Thanks
Edit:
- The MSI*.tmp files do not appear while in Safe mode
- Windows version is: Windows 10 Pro N
- When the files are popping up in the 'installer' folder, there is a file that appears then disappears when all 11 files are created; I copied this file to another location before it disappeared, name is inprogressinstallinfo.ipi, per the contents of this file, it appears to be related to ESET Inspect connector program...
Edit2: Stopped the EraAgentSvc service (ESET Management Agent), and it stops producing these files... It may got corrupt somehow... Uninstalled and reinstalled it, it is not producing these files anymore... Case closed!
Cheers!!
