A process VShieldScann (VShield Scanner) frequently gets stuck eating ~50% (and occasionally >90% with 2 stuck) on my MacBookAir running OS X 10.6.8. The Activity Monitor shows the CPU usage but not the process. Only a terminal window with ">top -o cpu" shows the VShieldScann process(s) running with the high CPU utilization. Seems no way to kill the process or to prevent it starting except to reboot.
Thank you for looking at this.
Well, that looks pretty much like a defective McAfee installation. Try uninstalling and reinstalling it and then run MVT again and see what it says.
Your post says this is a MacBookAir and gives us the OS version, but what is the actual McAfee product that you're running? Is it "McAfee VirusScan for Mac"? And is it a home consumer, or an enterprise version? I've seen a similar question to yours in the corporate area, posted last year.
We don't get too many Mac questions on the forum, so this is an interesting one. I've found lots of references to VShield, a product from VMware, but the name seems to have been around a lot longer than that in connection with McAfee (I've found instructions and user guides from as far back as 2002).
If Jai Prakash comes back with something relevant to your question, I'll hand over the thread to him. You really need someone who understands the product better than I do. If all else fails, you'll have to use the online chat or email option and ask for help from tech support.
Jai Prakash and Hayton,
I've uninstalled and reinstalled. The runnaway VShieldScann process returned. (It typically runs half of the available CPU cycles.) The process does not appear when first booting up but appears after visiting certain webpages. I'm still looking to find a guarenteed trigger webpage.
The product is McAfee Internet Security,, home version, Version 18.104.22.168 (921); Anti-malware, Version: 22.214.171.124 (579), DAT Version: 6500.0000, DAT Creation Date 10/15/11; Appication Protection, Version: 126.96.36.199 (549); Desktop Firewall, Version: 188.8.131.52 (536); SiteAdvisor, Version: 1.2 (125), Affid: 0
The updated MVT results following the current install are below.
Again, thank you for assistance.
Im confused , MVT report states that the installed product is a Desktop firewall application , assuming it’s an enterprise program ‘
Could you please post us with a screen shot of your security center , that would help us to assist you quicker
I also have very high CPU usage, 70%, causing the fan to work loudly and often, as in the posts above. This happens on my Macbook Pro using Mac OS Sierra, 10.12.6. and McAfee AntiVirus Plus. How can I remedy this? Thanks for your help.
I also have similar problem. My i7 cpu MacBook Pro with OS Mojave v10.14.1. It will sometimes freeze the computer completely.
McAfee Internet Security is: v184.108.40.206 (206)
Anti Malware: v220.127.116.11 (100)
Site Advisor: v4.5.5 (115)
Running MacBook Air (late 2014 model) using OS 10.12.6. McAfee All Access security 18.104.22.168. Home computer, not enterprise.
I often in the past 6 mo or so have been noticing slowdowns and near-freezes of the computer,even though I have had McAfee All Access security installed for several years. When I check the Activity Monitor utility I find multiple instances of VShield Scanner running usually using about 250 MB of RAM, or sometimes up to 400 MB or more each. Also several other instances running simultaneously typically using 30-40 MB of ram. Processes belong to root. They have to be force quit to get rid of them and then things will be ok for a while. However usually soon after there is another slowdown and I find that several instances of VShield Scanner have respawned. It occurs regardless of what browser is used (Safari, Firefox or Chrome). The problem seems to be a little worse when using Chrome. (I have a suspicion, but I am not sure, that the problem actually started after I installed Chrome, but uninstalling Chrome did not get rid of it.)
Since the MacBook Air has only 4GB of RAM VShield Scanner is hogging a lot of it (typically up to 2GB worth). I am seriously thinking of just dumping McAfee and going with MalWare Bytes alone since this problem does not seem to be fixable.
