How to completely clear detected rootkit?

[Banana]

After getting my PC back from a repair shop I heard that the owner of the shop was known to install rootkits on machines that he worked on. Rogue Killer found this (see attachment). I allowed RogueKiller to delete the files and daily scans since haven't reported back anything else. I still seem to have the .exe that he used to install it on my PC. Is there a way to clear my machine of this and other similar files safely, without accidentally reinstalling the rootkit?

Hi,

Welcome to Adlice Forum.
Could you please attach the JSON report with your next reply ?

The detection was about a month ago. The furthest back the reports go is to the 2nd of this month. I don't recall deleting any though, maybe reports are cleared after updating.

Hi,

Latest scans didn't detect anything. Your computer is clean.
The GPU-Z-v2 detection is related to a temporary driver used by GPU-Z and not linked to any kind of rootkit.
