Within the last 5 days someone (can't remember which Apple support thread it was on, sorry!) has discovered that the root of this horrendous problem actually lies in the interaction between the AppleMobileDeviceService.exe and a number of anti-virus programs. These include PC Tools Spyware Doctor, Norton, Symantec and a host of other "big names".
I'd had the problem on a desktop machine. The problem is now solved, but what a Sherlock Holmes you have to be to sort it out!
I've used Spyware Doctor with AntiVirus for years (a very good program, BTW) and was running a recent version, 22.214.171.1243. I'm also using a laptop at the moment which still has this V126.96.36.1993 on it, and it's just done a "Smart Update" and tells me the program is up to date.Eeer, Excuse me!!
If one goes onto the PC Tools website there's a little note somewhere that says something along the lines "For usesr who have had a problem with AppleMobile......... etc, then they should upgrade Spyware Doctor to the latest version. Completely uninstall the version you have and install the latest version from this site"
OK I did that and lo and behold my desktop machine is now running V188.8.131.522.
So how come the version on my laptop tells me "Spyware Doctor is Up to Date"?
It looks to me like there's probably been a major blame-game job been going on behind the scenes between Apple and a number of Anti-Virus software suppliers. Given Apple's litigeous nature at the moment I can't blame these Anti-virus companies from keeping their heads down!
I imagine that all concerned have been working flat out to solve the problem - I just wish they could have agreed on a common public announcement to their loyal customers.
If anyone is interested you can have a look at my website http://www.satellitespy.net for some other interesting insights. Twitter @satispy.
Saucecoda -- you nailed the big bicture, I think (as did the person who directed us to the PC Tools site).
I was initially releieved at this thread because the uninstalls of iTunes worked -- till a new version. I knew the issue started around the time I updated itunes AND added Spyware Dr. w/Antivirus. Yesterday I "updated" the antivirus and the problem is gone...
Just checked my numbers -- I'm now on the same version...my other "unupdated PC" is on .....663!
Ha - don't care.
I also suggest that folks look for updates to their virus software. And shame on Apple. I suspect it's a plot to make PC users suffer a bit more.
After updating to new Iunes i came across the same issues (CPU load 100% / not able to connet to store / not able to update to iOs 5). But all solved thanks to this thread, thumbs up guys (and big FAIL for Apple as they're ignoring this all the way as it seems....). Here's the easiest solution without de-installing etc etc http://www.thebambers.me.uk/wordpress/?p=316
I'm no Apple Fanboy, but some of the comments above are over-the-top. Antivirus apps always cause problems w/ other apps -- I can't say that they always will, but they certainly always have.
iTunes is a pretty complex app offering lots of functionality. There are bound to be problems with smaller-market utillity programs like the ones listed above.
Uninstalling iTunes in exactly the order specified by Apple fixed the problem for me (12.5% CPU usage; I never had a blank Store screen). I'm not having any conflicts w/ my antivirus (Webroot) and antimalware programs (Webroot & Comodo).
Thank you very much to all of those who posted solutions! The solutions don't seem to work for everyone, though, so I'm not surprised that Apple doesn't have an official fix yet...
AMDS was taking until 98% of CPU, couldn't update to iOS 5.0 in my Iphone 3GS with iTunes 10.5 in Windows XP.
For the records: Uninstalled my two Antivirus: Thread Fire and NOD 32. Execute netsh winsock reset as above, restart the computer.
And everything is woking GREAT!!!
Thanks a lot guys.
Now I need an antivirus that doesn't interfere with iTunes 10.5
I found Covenant Eyes to be the culprit for me as well. Received an email from them today; looks like they've got a fix. I uninstalled CE and iTunes, Apple Application Support, the whole shebang. Installed the newest CE, and am about to reinstall iTunes again.
We have released a new version of our Covenant Eyes for Windows software that fixes a major conflict with iTunes 10.5 and also with Safari.
Use this link (https://secure.cvnt.net/member/download) to get the updated software for Windows computers, and then simply run the installer.
Last week Apple released iTunes 10.5. If you have not yet updated iTunes on your Windows computer, please first update to the new version of Covenant Eyes linked above. If you do not update Covenant Eyes for Windows you will not be able to get to the iTunes store and will not be able to sync iPod/iPad/iPhones.
I found this thread http://brianmorristech.com/?p=762 after reading some of this thread.
From the command line: netsh winsock reset worked for me.
My setup is Windows XP sp3 running the most current version as of the date of this post of iTunes and Safari plus whatever eisle they have been throwing in to confuse things
I hope this helps some of you
Thanks for mentioned my post about the root causes of this issue. This is a problem with Apple's software, not with our computers! Apple, please visit my post and fix this problem. For every one user that has enough computer knowledge to find this problem, there are probably 9 that don't know why their computer is so slow.
I list the main solutions listed in the forums and suggest the root cause -- iTunes' not liking LSPs! Many times LSPs are bad and they need to be cleared, but many times they are good. Bsecure's CloudCare is a good example -- having that installed will cause this problem. APPLE?
Thanks for the original post. This has helped me out now on a few systems.
Just for Google's sake, it has fixed:
AppleMobileDeviceService.exe taking up 100% CPU
Safari 5 stopped working
iTunes 10.5 can not sync with iPhone
This is the reason why I have moved over to VoIP and networking and as far away from PC stuff.
Thanks once again.
like everyone else... I am in the same boat with AMDS pushing my CPU usage to 100%, even when iTunes is not in use or open!
iPhone fails to backup... just stalls after 2 minutes, and is no longer recognized when connected to iTunes
iTunes store is just a blank page, even when I login.
and I tried all the fixes: removing all Apple software in order, uninstall, re-install, deleting the library.xml file and a few other I found online, and nothing f'n works!
since this started in July, and at this point, I just give up on Apple products and going to look into Android for mobile device. Apple couldn't give 2 sh%ts about Window users which is more than obvious.
