Greetings, Malwarebytes forums. For the past few weeks, my laptop has been running very slowly, with high temperature (the CPU even reaches 100C on some occasions, with the core voltage exceeding 20V per core). The fan would ran at max speed even when the whole system is in idle mode (I do open a few programs related to my work, but all of them are network-related stuffs and in idle mode). Curious, I checked the Task Manager and see one of my workplace apps consuming exactly 25% of CPU. Occasionally it would dip or raise above that level but it would revert back to utilizing 25% of the CPU (an i5-2520M@2.5). Even more curious is the fact that if I force close the application in question, the 25% CPU utilization would be transfer to another apps previously in idle mode (with 0% CPU usage), even as far as transfering that utilization to explorer.exe and jusched.exe, which is entirely unrelated and would never consumes that huge amount of computing power. Thus, I suspect that my laptop is infected with some kind of crypto miner designed to run at 25% of system resources. Even more curious still is the fact that if I turn off everything, or restarting the system, the CPU utilization would return to a normal level. So what is wrong with my system and how should I proceed to remove this threat? I'm worried that if this continues, my laptop would turn into a pile of plastic and steel garbage pretty soon. P/s: My colleague has an identical laptop with an identical set of work-related apps, and his experienced no problem so far.
For some reason while malwarebytes is running, the cpu usage is constantly spiking to up to 30% while the computer is idle. I decided to record it: https://www.youtube.com/watch?v=W94otr2F_qs Can someone please explain to me what Malwarebytes is doing in the background and why it's causing "System" to have so much cpu usage rather than the actual MB service process?
