Should I Quarantine these 2 Files?

After doing a full reputation scan I get the below 2 files. I did a google search on the first but should I quarantine them?

 

3234df.smi Poor - Very Few Users Age 30+ days

exexthost.ni.exe Bad - Few Users Age 30+ days

 

Sorry, I did a screen capture to attach but it doesn't look like I can do so on this forum.
