Recently, I've reinstalled the OS, along with formatting the HDD. All good, I've installed all the programs and stuff that I commonly use, and after a few hours, I get a notification from Malwarebytes, that it has detected RiskWare.BitcoinMiner, under ProgramData\Microsoft\Systemservice.

Since then, I've been getting constant windows errors of systemservice.exe missing. Malwarebytes has stopped complaining, so I'm guessing the problem's been dealt with, but you can never be too sure. It would be nice however, if someone could point me at how can I get rid of those errors, because they pop up randomly every now and then, and it's getting annoying.

 

P.S. I couldn't copy-paste the log contents directly, as it wouldn't let me post (thread too long), so I've uploaded them instead.

Hello. Thanks for your swift reply.

 

I've followed the instructions, but during FRST's fixing, I've got a sudden blue screen of death.

The machine appears to be running normally after restart.

Fixlog as requested.

Yes.

Once I hit Fix, I've let the program do its thing, but a few moments later, I've got a blue screen of death, so I'm guessing the process might have not been completed. Another thing I've noticed, is that shortly after I hit fix, and just before the blue screen, all programs closed, including Firefox.

Hi,

Please run the Farbar program normally.

Post a fresh FRST and Addition.txt logs for my review.

Make sure the box to create an Addition.txt log is checked.
