Memory leak on Mac OS 10.15.3 Catalina

I'm running on a 32GB Mac mini with Catalina and I'm getting regular memory leaks in VShieldScanner. I've seen an instance consuming 70GB although I usually catch well before it gets to that size. When this occurs there will, typically, be six or so instances of VShieldscanner running with one showing multiple gigabytes of memory used while the others will be say 200MB. I usually kill all instances and will then be good for a day or two.

Does anybody else experience this, or is it a know bug?

Re: Memory leak on Mac OS 10.15.3 Catalina

Hello @Giles 

VShieldScanner is a service responsible for McAfee scan.

Would like to know some more details to assist you further on this issue:

  1. Amount of data occupied in Internal storage?
  2. Installed McAfee version in the machine.
  3. Does the service use more memory when open a specific software in your machine?
  4. Does the service use more memory when during a scheduled scan?

To know more about scheduled scan, read this article How to confirm a scheduled scan ran successfully on a Mac

Waiting for the leak to recur and then will look at internal data usage - but to avoid misunderstanding can you say specifically what you are looking for here.

Installed version of Total Protection is (756).

I haven't seen a pattern w.r.t other running software - but for sure at least Safari, Firefox and Thunderbird will be running. I will take a look when the problem occurs.

Scheduled scan is weekly on Tuesday night - I will keep an eye on it.

Real time scanning is enabled.
