They do look a bit odd to me.
They all appeared over the course of two days and they are all only 1 KB.
It could be from something you installed. You could go into Program & Features or Apps & Features and have a look for anything installed on those dates.

This Bleeping Computer thread refers to some of those files and recommends AdwCleaner to clean it.

If they are still there after you run AdwCleaner, if it was me, I would just delete them to the Recycle Bin and leave them in there for a few days and monitor things just to be sure.


Edit: There is more info here in another Bleeping Computer thread.

Top of the list of your circled area is described as a rootkit after a quick search so not good, run the free version of Malwarebytes, see if it picks them up

Suggest you post on a security forum such as Bleeping Computer for individual instructions and not just follow instructions given to another individual. They always caution against that. Running AdwCleaner or Malwarebytes should not be an issue however

If it was a rootkit why would it get past Windows Defender?

Rootkits are made to evade detection, I don't have 11, but in 10 there was a Scan Offline option for Defender, worth a shot

Does MB not scan for Rootkits by default? When I ran a custom scan the Rootkit checkbox was not checked. MB detected no Rootkits...

MB does not scan for Rootkits by default, you have to check the box. If you want to be sure you are clean, post on a security centered forum, and provide logs and apply exact scans and fixes they suggest. I am not sure if any security experts are active here

All of the same files I have but they give no indication as to where they think they might have came from or even why they suspect a Rootkit. :unsure:

I did a quick test of some of the file types and some came back as various use audio files, have you recently installed or started using an audio editor (a lot of systems with discrete Sound cards will come with a bespoke application or tool)

this may clarify what any files you cannot recognise may be List of file formats - Wikipedia

Of course malware could also use these files purposely to hide their data files

You could try sending the files individually to some online checker like Virus Total

You found info on the file types I circled related to audio? I do use a SoundBlaster Sound Card with Sound Blaster Command software.

I just ran each of the files through Virus Total and each came back fully undetected.

It was a Google search for rtmeslt that lead to the above links. The users there all have these files in Program Data with OSArmor installed. I do wonder why the Bleeping Computer helpers suggest to delete these files. :unsure:

I do not know ONArmor so cannot comment, I personally use the pro version of BitDefender and have done for a number of years .

It's fully possible that they use these files extensions internally, and as they are shown as clean on VirusTotal (a site that I and many other members here use as they are usually very fast to find malware files often before the big names in Malware prevention). so as an Addon to check any files that appear and you are not sure what they are I would recommend it
