Checking CPU activity for signs of malware.
Checking CPU activity for signs of malware.
Hello, I observed that sometimes the CPU fans become louder. I checked Task Manager or MSI Afterburner to monitor CPU usage and temperatures. When I start them, the CPU usage drops to normal levels (1-5%) with just a browser open. However, after closing the program later, usage spikes again, jumping from 40 to around 57. It doesn’t increase significantly beyond that and not all cores are active. I’ve run virus and malware scans using ESET, Malwarebytes, and RogueKiller. Two entries appeared in the risk list—one from a software I haven’t used in years and another from something unfamiliar. That’s all I know. Could you help explain why this is happening? Also, in games I didn’t notice any noticeable FPS drops, so it mainly bothers me when the fans get loud while idle.
Your CPU gets active for thousands of background processes, so don’t worry about minor interruptions. The latest Windows version is the most vulnerable to malware.
I hadn't realized it could occur before; I understand it might happen with certain processes. I'm aiming to keep my system tidy, and this has only become noticeable recently. Would it help to monitor anything? Or are there any tools you recommend for cleaning windows more thoroughly? I typically use Revo Uninstaller to remove items and clean up registry entries and residual files.
Recent times have seen increased activity from Windows background processes, particularly the Antimalware service.
