I am using Windows 10 and accidentally installed an executable file I downloaded that turned out to be malicious. Among the obvious symptoms that occurred (adware, browser setting changes, etc), my system became unusably slow. I have run and cleaned with Malwarebytes Anti-Malware and Kaspersky Total Security multiple times. Multiple maleware and trojan problems were found. Also, Windows Defender detected and removed problems on its on. No more issues are being detected. The malware installed/problems I was able to see were:
Space Sound Pro
"Activate Windows Now" pop up window.
(Since I thought the MalwareBytes and Kaspersky could be causing the slow system, I completely uninstalled these programs and all related files. I'm not sure any logs of the problems found still exist)
However, my system is still extremely slow. Task Manager shows disk usage at near 100% most of the time, with the following processes using it the most (randomly):
System and compressed memory
Service Host:Local System (Network Restricted)(8)
Runtime Broker (this has also caused out of memory messages)
I have performed with no problems found:
System File Check
DISM restore health
I have played with the pagefile sizes in Advanced System Settings with no luck.
When booting in Safe Mode, the problems stops.
Am I still infected? Is there a way I can stop the disk thrashing?
