Hello DreamlessKai,
MBAM is not your issue, reason why I asked was because MBAM comes with a 14 day trial period for their Premium licence which offers full AV protection that could conflict with another AV such as ESET, after 14 days unless upgraded MBAM reverts back to the free version that does not include real time AV protection that could such conflicts.
I would strongly suggest that you do not power down the notebook for the time being as there is a high chance that it may not boot up at some point.
First thing that I would suggest that you do is back up of your important data in case the HDD fails, an external USB HDD would be best for this.
What the read error rate warning normally suggests, being that this is a notebook there could be a poor connection between the contacts on the HDD and those on the motherboard but as the computer will at some point boot up it is most likely a problem with the disk surface or the read/write heads, the latter is irreparable and once your data is secure I would check for any warranty there may be for the drive and replace the drive asap.
