SymAVScanDaemon pegging my CPU

The SymAVScanDaemon is beating on one of my external disks, and sucking between 50-150% of my CPU.  I let it run for a day in hopes that it would finish whatever scan it's working on, but it hasn't completed and there's no way to know what kind of progress it's making.  It has currently run for 17:20:38.60 CPU hours.

 

I don't think that the Daemon is in a healthy state.  In the console, every three or four seconds or so, I see:

Re: SymAVScanDaemon pegging my CPU

[ Edited ]

dondo,

 

It looks like SymAVScanServer is actually not pegging the CPU, but our alerting application (SymUIAgent). You can confirm this by looking in Activity Monitor.

 

However the real issue is this line in your syslog (which was very helpful, thanks!): 

/3/2009 1:47:33 PM /Library/Application Support/Symantec/SymUIAgent/SymUIAgent.app/Contents/MacOS/SymUIAgent[62621] Norton AntiVirus QuickMenu could not connect to SymSharedSettings (Invalid settings)

 

It seems as if somehow your settings file for Norton AntiVirus became corrupted. It might have been because your computer shut down unexpectedly, or something happened while we were trying to write the settings.

 

The easiest way to fix this is to simply uninstall & reinstall. This is unfortunate,  and I'm going to push for a simpler solution to this. If for some reason you cannot uninstall, you can try the following (I've never tried this before so it may not work:)

1. Open the Terminal application in your Applications -> Utilities folder.

2. Type (or copy & paste), without the quotes "sudo rm -f /Library/Application\ Support/Symantec/Settings/1/com.symantec.nortonantivirus*"

 

Press return, type your password when asked and then restart your computer. If it works, that will delete the corrupted settings file and help get things working again.  If you can't get that to work, or aren't comfortable with Terminal, try un-installing and re-installing. Very sorry for the inconvience.

 

Ryan

Re: SymAVScanDaemon pegging my CPU

Thanks, Ryan.  

 

In the original post, I noted:

The SymAVScanDaemon is beating on one of my external disks, and sucking between 50-150% of my CPU.  I let it run for a day in hopes that it would finish whatever scan it's working on, but it hasn't completed and there's no way to know what kind of progress it's making.  It has currently run for 17:20:38.60 CPU hours.
That information was from the activity monitor; it was definitely the SymAVScanDaemon which was eating my CPU.  From what you say, there may have been a couple problems.

 

 

Unfortunately, I couldn't wait another day for resolution, so I force-quit the SymAVScanDaemon which immediately resolved the CPU issues (but undoubtedly leaves me unprotected for the nonce).  

 

I'll let you know if it recurs.

Re: SymAVScanDaemon pegging my CPU

I am very unsatisfied with this product. 

 

There are definitely two problems, possibly related, one more serious than the other.

 

The more serious problem is that every time SymAVDaemon runs it pegs my CPU (100+%).  This occurs primarily when I connect my external hard drives, though it has happened once on startup.  I am forced each time to kill the daemon by hand, which undoubtedly obviates much of the benefit your product offers in the first place.

 

I have had situations where my CPU has unusually high load (70-80%) while the console shows the issue with com.symantec.uiagent.application  having a bus error every several seconds.  I do not know what triggers this, nor how to stop it.

 

I have been unable to uninstall/reinstall.  When I run the Symantec Uninstaller it reports that "The Symantec Uninstaller did not find any Symantec products to uninstall.  The Symantec Uninstaller removes Symantec products from the current startup disk only."

 

Also, in an unrelated but perhaps symptomatic issue, I just asked your forums to resend my login/password and you sent my password in an email IN PLAINTEXT.  You're a security company?

Re: SymAVScanDaemon pegging my CPU

Sorry to hear about the problems. It sounds like you could just disable Auto Disk Scan which would fix the problem. I don't know what is causing the error, but disabling Auto Disk Scan should fix it if this issue occurs whenever you connect an external hard drive.

 

Auto Disk Scan is more of a convience feature than a security feature. AutoProtect will still catch any viruses on the external drive when they are accessed. 

 

I am not sure why you're having problems with the Uninstaller. I can send you a script we have that will delete files from your machine if you send me a PM with your email address in it.

Re: SymAVScanDaemon pegging my CPU

Your product does not work.  I want to uninstall it.

 

Your uninstaller doesn't work.

 

You did not respond to the PM I sent a couple weeks ago.  

 

I'll try again.  Please send me the scripts so I can stop your product from degrading my system's performance.

Re: SymAVScanDaemon pegging my CPU

You never explained what problems you have with the uninstaller. Did you try using the Uninstaller to remove the product, and if so, what problems did you experience?
