guegae.exe how to remove it?

[Cactush]

So, I turned on my PC this morning and I noticed that I had a file called guegae.exe, guegae.scr and passwords.txt in my External Hard drive.
A Google Search told me this was a trojan, but I Scanned with Malwarebytes on a Threat Scan, and It couldn't find anything.
Please, can anyone help? I don't want this thing to linger.

Hello Cactush,

So that everyone is on the same track please see the FAQ which includes guidelines for this forum and instructions in post #2 on how to provide the preliminary Farbar Recovery Scan Tool and aswMBR logs used for analysis.

Then start a new topic providing the logs as shown in that sticky and a volunteer analyst will assist. :)

Best regards.
