Erix's 2 release notes for the 4.4.10.144- BETA suggest that there's a known conflict with Windows Update, but if a fix is imminent I'm not going to waste too much time diagnosing the intermittent high (excessive?) CPU activity by my Malwarebytes Service that I can see in Task Manager unless it continues after the stable edition of Malwarebytes v4.4.10 is released.īased on comments by other Inspiron 5584 users in the Dell forum I actually suspect that the problem is with a faulty cooling fan, and not excessive CPU activity by my Malwarebytes Service, per se. Right now I'd just like to know if there's a thread somewhere in this forum discussing a known conflict between Windows Update and Malwarebytes where I can find more information. I've attached the requested mbst-grab-results.zip file, but I'm not expecting anyone from Malwarebytes to help me diagnose the cause of high CPU temps on my Dell Inspiron - at least for now. Just an aside, but the only other time this loud fan noise seems to occur is when Malwarebytes runs my daily Threat Scan.Ħ4-bit Win 10 Pro v21H1 build 19043.1288 * Firefox v93.0.0 * Microsoft Defender v.6-0.4 * Malwarebytes Premium v4.4.9.142- * HWMonitor Free Portable v1.44ĭell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G 256 GB NVMe SSD, Intel UHD Graphics 620 Edited Octoby lmacri

I thought the bearings in my fan might be starting to fail because the fan is so noisy during these daily Microsoft Defender virus definition update checks, but after reading Erix's release notes for the latest BETA test version I'm beginning to wonder now if my Malwarebytes Premium real-time protection is interfering with Windows Update and contributing to the high CPU usage.
