Getting a csrss.exe / Bitcoin miner related problem

  1. Twice now I've found that csrss, and a different exe, vcsrss, have been found in a folder with dll files named coineng.dll, miner.dll and the like. I'd tried to shut off the programs in task manager, but found that they autostart themselves instantly, so I never had time to delete them. However, I did find that shutting off internet access allowed me to end the programs and wipe the folder in AppData clean. My computer had been running very slowly, and I figured out that my computer had somehow been infected with (by the name of the .dll's, im going to make a wild guess) a bitcoin mining malware/virus or whatever you want to call it.

    The first time I figured that I wouldn't have the problem again, I didn't worry about it. But it's appeared now, a few weeks later. I thought about scanning for some potential threat elsewhere on my computer, but seeing as I've deleted the source of the CPU slow off the computer, I doubt MSE is going to alert me to anything, but I know what the programs are named, so is there any possible way to use MSE or something else to prevent the exe's and .dll's from getting into / running on my computer again? I can still run MSE just in case, but a full scan last time didn't pick anything up, and I don't foresee that outcome changing.

    Any help or information on the topic would be much appreciated. If you need any info from me (like the steps from the sticky thread, if those are applicable [though I didn't think so since I kind of know what the problem is]) just let me know what to do.

    Thanks in advance!
