What is VShield Update?

Do you have this installed? http://www.vmware.com/products/vshield/overview.html

A Google search says that VShield is part of VMWare. Since I don't do anything with any code from Microsloth I can be more help then that.

I had the same problem. I've seen it pop up from time to time before 10.7 but it's been running near-continously after upgrading. I force quit VShield in the Activity Monitor. Then, poking around, I found the /usr/local/vscanx directory. This contains an unistall command which I exectued.

After force quitting in Activity Monitor, try the following in Terminal.app:

$ cd /usr/local/vscanx

$ ./VirusScan\ Uninstall.command

I saw the following:

VirusScan has been successfully uninstalled.

After it was done, all was deleted. Time will tell whether this screws up anything else... (Thank you Time Machine!)

Thanks ebw-cs!

I restored Viruscan from Time Machine (both the App and the Scheduler in the Utilities folder). Once the restore was complete, fired up Terminal and entered your lines of code and saw the same responses you recorded above.

All is quiet on the CPU front. VShieldupdate appears connquered.

Thanks again!

Just for clarity, while VMware does have products and APIs called vShield, this Vshield is an element of McAfee's security product for Mac.

If it's any consolation, Mac users at VMware suffer from McAfee's resource hogging, too!

I had the exact issue mentioned at the beginning of this discussion.

As Roarers suggested, I did have a copy of McAfee's on my system, now rendered incompatible by lion. I ran its uninstall process, and the problem was instantly and completely fixed. I do not have VMware on my computer, so the process was indeed from McAfee.

Prior to uninstalling it, my CPU usage was always at 45% even when doing nothing, my fans were blowing between 3500 and 5500, and my CPU was 170 degrees F.

I'm really glad this fixed it.... CPU usage dropped to 4%, temp dropped to 120F, and the Vshieldupate process is no longer running.

Thanks, Roarers.

Thanks cmd87, that fixed it on my end.

A usefull script that can be run to do this automatically is called virusscanuninstall version 8.6. I searched for VirusScan osx removal tool and found this link - http://mcafee-virusscan-uninstaller.en.softonic.com/mac

VShield is the update engine of McAfee security scan for mac. If you open your McAfee preferences, you can see when it starts an update of the virus library. it will be on the same time your processor is overloaded.

So, aparently updating McAfee is a very heavy business...

I have no solution for this, accept uninstalling McAfee.
