Auto-protect/Sonar slows computer
I'm using Comcast's Norton 360 along with Malwarebytes with W10. I know sometimes these two don't play well together. So I've closed MB. Computer is slow loading apps, MS Edge, Firefox, etc. It slows loading web pages after some time. All is fast again when I disable Auto-protect/Sonar. This problem is somewhat recent, maybe a month now. Before that, MB and Norton worked perfectly together. All products are up to date. Whether running MB or not makes no difference. The computer returns to normal speed consistently when I disable Auto-protect/Sonar. I've also excluded non-essential drives and network devices. I've been using PC's for over 30 years so I'm used to solving problems. It really seems to be something with Auto-protect. Anyone else solved this problem?
