Hi There

I noticed some strange activity on cpu and disc after antivirus software started scheduled scan. Is this normal or something that I should look more in to? Just bought this new laptop and it seems to be causing problems on other things as well.

McAfee is just plain awful, it has bad signature detection as well as poor resource hogging. I'd just get rid of it asap and get something like kaspersky.

I would completely uninstall mcafee, including using the mcafee uninstaller tool (MCPR):

https://service.mcafee.com/webcente...showHeader=false&_adf.ctrl-state=1an6uwl3pg_4

Then reboot, make sure Windows Defender is active, then I'd do a complete malwarebytes scan cos you just can't trust mcafee.

Then reboot and see if the issue is still present. It probably will be.

If so, then reinstall the audio driver firstly, then any secondary audio processing like Creative or soundblaster cinema or whatever.

I'm not a fan of McAffe either but what you are seeing is quite normal. When McAfee (or any other anti-virus) runs it reads every file on your disk(s) so it's no surprise that your disk activity rockets. Also, performing read I/Os to disk uses significant CPU cycles and when you add into this the work that the McAfee virus scanner is doing it's not that surprising that your CPU hits 100% either. You may find that you can adjust the priority of the McAfee scanner so that it doesn't try to use all available CPU cycles.
