MB3 slows computer

[lsymmonds]

I am new to these forums although am a long time user of the home version of Malwarebytes.  I downloaded the 3.0 pro version on my two PCs recently (Dell XPS 2750 and Windows Surface laptop both running Win10).  I noticed immediately that the Dell machine slowed to a crawl during the Threat scans.  A check of the Disk utilization showed that it was at 100% with MWB at the top of the list and so was the memory utilization, however I hardly noticed the scans running on the Surface which has less resources.  Thinking that I had too many junk apps on the Dell, I cleaned out the app list, got rid of orphan registry entries, and defragged the disk, however that hasn't seem to have made any difference.  The only thing I could think to do was to schedule the scans to run at 3am, but I would be interested in your opinion as to why I am seeing such a difference between the two PCs.

I split your post from the original topic as the two weren't related.

As for your issues, are you running the scan with the MB3 Window open? If so, this will cause MB3 to take up more resources while running. If you close the MB3 UI to run your scan, it should use less resources
