10.8.2 Browser CPU Usage

My MBP 2011 is having some serious issues with CPU usage for both Safari and FireFox. An idle browser will start to consume >100% CPU at a constant rate for no apparent reason whatsoever, and it will continue to do so until I shut it down. I once left the browser open, walked away, and from a full charge, my MBP battery was depleted within the hour, if not sooner. In fact, with FireFox, the CPU usage becomes so intense that I can't barely drag the mouse to the dock to termiante the browser. I reinstalled my OS at one point, and the issue persists.

All I can suggest is to try chrome. I've used for a few years on PC and on my Mac for the last 14 months with no problems what so ever.
Of course you could unintstall and reinstall FireFox and test. Not so easy to do with Safari as it is part of the OS and the only way I know of reinstalling is to reinstall the operating system. I have no idea if it can be uninstalled.

    but now, when i use rekonq (also tested arora; same issue), cpu usage for the browser shoots up to nearly 50% and stays there. also, pages don't load unless i move my mouse around. flash is worse as well.
    (note: after my upgrade, i got a black screen on booting up. i had to use the 'nomodeset' option to disable kms. this probably isn't related, but i thought it might be worth mentioning.)
    any ideas?

    you're right. i forgot that i made some changes to my igoogle page. the chat function is the culprit. adding it causes the spike. i've reported the problem. thanks for the help!

  • Firefox very slow and high cpu usage!! (all other browse slow too)

    Sorry, I asked it in 'Newbie Corner' , but still no resolved. so I asked here.
    Hi all,
            when i open a website just as www.sohu.com,   my firefox (3.0.3) hang on, then display the web page very slow , and slow scroll , firefox cpu usage nearly about 100.
            I tried some sloution,like modify /etc/enviroment to set MOD_DISABLE_PANGO=1,
    or disable 'tell me if a web site ...' in firefox security option.
    but still slow.
    some people says it's must because flash or some js.
    but when  i try it in windows or ubuntu, it very fast, not like in archlinux.
    so i think some thing wrong in archlinux.  I need your helps.
    thank you.
    p.s.
    1.  pacman is very fast (the speed of wget about 400k/s)
    2.  gnome web browser like firefox , slow and high cpu.
    3.  the list of output of 'locale'  about 11 lines.
    4.  i have already set host name like wiki says.
    5.   the system is  a new system

  • Flash causing abnormally high CPU usage and overheating when browsing internet

    Hello,
    Flash Player (Safari Internet plug-in) spikes to 110-120% of my CPU usage while browsing the internet. This also causes my computer to overheat. (This also occurs when using Firefox)
    I am running OSX 10.8.4 and I am using Adobe Flash Player 11.8.800.94
    I have tried uninstalling through the Adobe uninstaller and resetting Safari and my computer.
    I contacted apple care and they said it was a problem with Adobe and I needed to contact you guys.
    Thank you for your help.
    Justin

    The link you posted is fine. its only around 9%
    Here is an example of a page that causes my CPU to freak out
    http://forums.prosportsdaily.com/forumdisplay.php?143-Soccer

  • Firefox is eating up between 90% CPU usage to %230 CPU usage, while on a text-only page. I've tried many of the fixits. They didn't work. What can I do?

    I've cleared cookies multiple times
    I've emptied the cache
    I cleared my download history, and a majority of my browsing history
    I've tried having hardware acceleration for both flash and firefox on and off
    I turned off all my apps and plugins and when that did nothing I turned back on the ones I need. I never had a lot of apps to begin with. only a max of 5. I had quite a few plugins, but i disabled all but quicktime, flash, and silverlight. I have those three set on "ask to activate" so none are "always active" anymore.
    I also tried a couple things from the FAQ and forums here about changing a few settings in the "about:config" setup.
    A few of the above things initially worked, but after a day or two it'd be back to sucking up my CPU and memory. I would then try the same thing again, and this second time there would be no improvement.
    The real memory will fluctuate between 200 MB and 1.7 GB, and has done so for quite a while.
    Even after I've left streaming sites, and sites with lots of images, and I'm not downloading anything, the memory and the CPU will still do that. I only have a handful of tabs open at a timeusually, and all of them are mostly text. I'll quit and reopen firefox, which will initially bring the memory and CPU usage down, but it inevitably climbs up quite quickly, regardless of my tab usage. It'll be the same if I'm playing a flash game or scrolling through blogs.
    I never had any of these problems with Firefox 23, and my internet usage habits haven't changed at all. I had some of this slowness a few times with version 24, but nowhere near as bad as this, or as constant. Almost everyday I end up googling for other ways to speed things up. Everything I do never slowed down Firefox on earlier versions.
    I've tried all my usual tasks on Safari which will never climb above 30-40 MB of memory, even on netflix streaming, or flash games, and the CPU will average around 8 and 11%.

    i'm also having major CPU problems w/ FF 29.0.1. when i restart the app it calms down again but after loading tabs it steadily climbs up to 100% after not too long. i have checked out the 2 CPU links/articles above and do all the basic troubleshooting and tips, but with all the FF tools & add-ons isn't there some sort of CPU monitor that has the ability to display which extensions/scripts are hogging the CPU? Activity Monitor on Mac just shows the total used by the app. it's impossible in my case to efficiently disable dozens of add-ons & scripts, restart, and test each one by one b/c it can take several hrs before the CPU starts to spike high again. i have no time for this.
    thanks

  • High CPU & Memory issues - Excessive and unnecessary CPU usage in Firefox for Windows (see also questions1003966 & 998289)

    I am using the latest version of Firefox, 32.0.1, on an HP Pavilion dv7-4141sa laptop computer, running Windows 8.1 Pro 64-bit. There should be more than enough power here to run a browser without any problem, yet the computer is regularly being overloaded by the browser's resource usage.
    I am currently measuring typical average CPU usage of 45% - with the browser minimised. That is to say, Firefox is not doing any browser jobs - it is not drawing on the screen - but it is using the most CPU of any process currently running. Why?
    I am an ex-software engineer, and my understanding of current application development technology is limited, but I think I can say with some confidence that many techniques and software architectures exist that enable the suspension of program activity, or at least its reduction to a very low bare minimum, when the program is not actually carrying out its design function, which is in this case to draw pictures of website data on a screen.
    There is a very serious problem here, one which means that I cannot run Firefox all the time, but have to kill it when I am not actively browsing, otherwise other applications cannot run to their full capacity. This is a great pity, because I have committed a lot of effort to making Firefox my primary web tool. It manages all my many bookmarks, contains my secure password manager (LastPass), manages my web security (via NoScript, AdBlock, and FlashBlock), just for a start.
    Before any well-meaning moderators or other commenters start down the usual trail of "have you done this, tried that, disabled the other", I should point out that I have followed all the advice I can find, with no positive outcome. This computer is running a fresh installation of Windows, and a fresh installation of Firefox. At the moment I am running a new test Firefox profile.
    The latest version of Adobe Flash, 14.0.0.179, is installed but disabled. When it is enabled and in use, Firefox's CPU usage seems high over longer periods, but overall there is little difference. It doesn't look as though the problem can be laid at Flash's door. A few other add-ins are installed, mainly those mentioned above, and Firefox is skinned with LavaFox v2-Green, but I have previously started from a clean installation, which has made little difference after an initial period during which things seemed to be better. Turning off or disabling various add-ons has made no discernible difference.
    Just now I turned Flash on, and after a long period with Firefox minimised, Resource Monitor reported Firefox at 8% average CPU and FlashPlayerPlugin at 0.32%. While running a small video, RM reports FlashPlayerPlugin at about 45% and Firefox at 8%. After the video, Flash went back down to around 0.4%, and after a bit more browsing Firefox went to around 17% minimised. There seems little rhyme or reason here, except that Flash does not seem to be the culprit, although Firefox does seem to consume less when fewer tabs are actually active, as you might expect. I just refreshed more than a dozen tabs, and now Firefox is at 30%, but still not back up to the higher figures. Weird.
    The CPU usage does vary a lot around the average, but 30% is still a lot for a program that shouldn't be doing anything above the minimum status maintenance, and still puts it at the top of my Top Process Monitor list. (Right now it's gone back up to 45%, without my using it in any way).
    I have Telemetry turned on, so presumably Mozilla is recording some of the relevant data.
    This is a very serious fault, which is more or less reproducible and which a lot of people seem to be experiencing. Probably more people have it than realise, because most users will not know anything other than that their computer slows down for some non-obvious reason; they may just think it's something to do with the computer itself, not knowing how to use the Resource Monitor and interpret the results.
    Oddly, the problem does not seem to occur when running Firefox under Linux Mint 17, where the response is snappy and the CPU usage ostensibly low; I am going to look at this in more detail shortly.
    I am not posting here for advice, but for information and as a form of bug report which hopefully other users will see. It will hopefully spare them a lot of effort and time in trying a lot of recommended "solutions" which will not work. The problem is inherent in the software, and can be solved only by Mozilla.
    I am willing to supply any diagnostic data requested; as I said above, I have also turned on "Telemetry". However, I will not be trying out any more reinstallation/new-profile/add-on disable-enable-delete cycles unless I am asked to for very specific reasons. Please do not suggest courses of action which have already been mentioned elsewhere on this forum. I have tried them all.
    The situation is very disappointing, but I have confidence that the Firefox developers will pin down the fault eventually and engineer a satisfactory solution that makes it viable to leave Firefox open all the time. Even with that restriction, it's still far better than the alternatives.

    I share jmward's frustration. This is not a bug report so much as a request for a badly needed feature, ie the ability to have Firefox be able to tell us which tabs on which windows are eating time so we can target them. There are some very poorly written web pages out there which just plain loop while making no updates or inconsequential updates on the page.
    This is not a OS problem; jmward runs Windows and I run Linux but we have the same issue. It is not a question of Firefox plugins or extensions, or even viruses; I have a new, clean Linux install but have the same problem on both my regular Firefox AND on a FRESH install of the latest Firefox (35.0.1) which has *NO* non-default plugins or extensions.
    Here is an example of a web page which will eat 100% of one CPU's time:
    http://patch.com/massachusetts/arlington/arlington-woman-allegedly-attacks-neighbor-snow-blower-0
    I will attach 3 images to back up my claim. All of the images show my dark blue system monitor (gkrellm) superimposed on the web page. The top graph shows CPU time. I have 4 CPUs in my machine, so 25% means the web page is eating 100% of one CPU equivalent.
    The first image shows the load of the offending page with elevated CPU usage along with the download net activity on eth0, but the CPU activity does not stop when the download activity is over.
    The second images show the steady state 100% CPU equivalent of this page just sitting there apparently doing nothing. It IS, however, doing at least two different things. I know from my regular Firefox where I have "Remove It Permanently" installed that if I remove the the little weather indicator in the upper right of the offending page that CPU utilization drops to about 40% of one CPU equivalent. If I use RIP to remove everything else right down to a bare screen that 40% utilization stays until I delete the tab.
    The third image shows the CPU utilization drop to zero when I delete the tab holding the offending page.
    Now I will add a note here: If the offending page is NOT the top tab in a window then it stops eating time. The offender will also stop eating time if I minimize the window. However if I have another window up but leave the offender up on top in its window it continues to eat time even tho I am looking at another window. The offender will continue to eat time even if its window is completely covered by another window, and it will also eat time if I switch to another desktop.
    I will often have half a dozen windows open, and there are many pages out there which will suck endless CPU time. Unless I want to open up a new tab on each window before I leave it there is likely to be some tab on top eating time uselessly. Get a couple of those going and Firefox becomes sluggish and can even stop responding for many seconds.
    I guess I not only want to have Firefox tell us which tabs are eating time, but I would also like it if Firefox would stop giving CPU time to any tab which is not visible because it is covered by some other window and/or it is on a desktop which is currently not showing. If you can stop a tab's CPU usage by reason of tab-not-showing then you should also be able to stop its CPU usage when the window is covered or on the not-top desktop. Indeed is there any reason to not schedule absolute CPU utilization priority to the visible tab on the window with focus and give time to the other tabs only when the visible tab isn't using time?
    My final thought on this is that I have had Firefox SO tied up sometimes that I swear their are web pages which are eating time even tho they are not the top tab. I regret that I do not have an example to show you. But Firefox grinds to a complete halt on a regular basis, and that is not acceptable. I am a programmer with long experience in multi-threaded programs so I *know* there is no reason you cannot do better. If there were another browser around which had the commitment to privacy which Firefox has I would probably switch out of shear annoyance. :-(

  • High CPU usage without any application running on the laptop

    Hi ,
    I saw some earlier posts as well but I am not sure if anything is helping me. I have a HP Pavilian Dv6. Its with me for now since 2009 or so. It was all running very well till last Nov - Dec 2013 timeframe. I had many bulky work done on the laptp like video cutting editing , along with audio edits , fairly well. I used it mostly for videos and no games though.
    Since Nov - Dec 2014, all the videos started slowing down, extremely jerky, and not catching up with the audio. Slowly the problem became worse . After 10 mins of video it just stopped and hanged. It did it with every site and any format of video including videos on my C Drive. I earlier tried a lot of things, playing around with flash player thinking that's the culprit. Did not help. Browsers changed, Mozilla, internet explorer , Chrome, everything no change. Then till around last week, I tried tested, uninstalled a lot of programs, also did Microsoft system restore and seen , the CPU continously behaved reaching to its 100% peak and the videos getting shot down. Just no change. Last week , I got desperate and finally reformatted my hard drive and did a factory restore on the laptop. IT DID NOT HELP !! The laptop behaved really like a good puppy for a few days , Youtube and what not and again since yesterday it has been shot down ! No videos will run. What's more even a DVD video is not running , nothing on a browser a simple DVD player DVD play is not running. Jerky videos and hanging issues.
    Everything boils dows to 100% CPU usage. Even if I am closing all my applications , it shows 'system' as the process using 90-100% CPU. Without any browser or even a notepad option open. There is also a prgram 'dwm' which eats up the next big slot of CPU.
    I am really tired of this and not able to enjoy anything. Please suggest what could be the issue here and how can it be helped?

    Just to add the laptop is HP Pavilian DV6 , model Dv6t - 1300.

  • High cpu usage after a while

    Sometimes, after a while, firefox (36.0.4) uses up 1 core of my CPU (is a quad core due to hypertreading). The way it happens is really strange. Many tabs without a problem until suddenly ff decides to floor it. This is alway in the run, not on startup or close. All add-ons need to ask my permissions to be activated, this includes flash.
    On close, I ordered ff to clear all history and cookies.
    Notes that could be important (The behavior encountered while using it. This varies from time to time):
    opening new tabs (a lot or a few) => "heavy" load during site loading, then idling
    ==> The above makes sense
    - same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript
    ==> The above seems odd
    - Browser is idle in the background (not actively using it). Then all of the sudden "lets floor it until closed".
    ==> The above seems pretty odd
    - When confronted with high CPU usage, closing ff doesn't close it (the ff process remains active. Not a ff process, THE ff process). => High CPU usage remains
    ==> The above looks like that there is definitely something wrong here
    This last one has some other things to keep in mind
    - When it happens and I close ff, upon restarting it it will ALWAYS ask to close ff. After confirming to close it, it will start and behave normally.
    - When killing ff via the task-manager, or other means like powershell commands, restarting it will result in an idle ff even after every tab is loaded again.
    I hope this isn't a heisenbug and there is a solution to this, a reboot ff button would be a nice workaround though. I personally think that it must be some routine in the code that decides to go nuts for no reason.
    If you need further details, feel free to ask.
    Thanks in advance

    Tried those before and tried them again. Unfortunately, the problem keeps repeating itself at random times. As said, sometimes it doesn't occur and sometimes suddenly it does. Keep the following things in mind about this, what seems like a heisenbug, behavior.
    - opening new tabs (a lot or a few) => "heavy" load during site loading, then idling
    ==> The above makes sense
    - same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript
    ==> The above seems odd
    - Browser is idle in the background (not actively using it). Then all of the sudden "lets floor it until closed".

    - When confronted with high CPU usage, closing ff doesn't close it (the ff process remains active. Not a ff process, THE ff process). => High CPU usage remains
    ==> The above looks like that there is definitely something wrong here
    As stated, a reboot ff button would be a nice workaround. I personally think that something like a tread must get stuck in some sort of infinite loop. Browsing in ff works just fine though. I just don't like the fact that I turns into a "gasoline guzzler".
    Again, thanks in advance

  • CPU usage while running Bex report

    Hello,
    Sometimes, when I run a Bex report with many lines the computer CPU Usage is 100% (=full ) for a long time. In some cases i need to do restart again for the computer.
    In the WAD  it doesn’t happened...
    Did anybody have the same problem? Is there a way to reduce the CPU usage?
    Please Advice,
    Amir

    Amir,
    This is "normal" behaviour in Bex with query's which return very long lists. The client computer already received all data, but is formatting the layout.
    Solutions:
    1) a faster pc with enough memory (512 mb) and win200 or >.
    2) a query with less return rows.
    The reason that in wad (web reporting) this is not experienced is because the formatting (rendering html) from the result table is done within the WAS (application server, which is hopefully faster then your PC...). Your browser only receives the html page..no exotic hardware needed for that..
    Any questions left: please ask; if you're satisfied please grant with rewards.
    Kind regards Patrick Rieken.

  • High CPU usage while display is asleep

    This is a strange one, and I've noticed it on multiple distros, and Arch is no different.  When my system is sitting idle with the screen on my CPU usage hovers around 5%, which I would consider to be perfectly normal.  However, when the display goes to sleep (no screen saver, just DPMS sleep) the CPU jumps up to about 25% and stays there until I bump the mouse (or do whatever to wake the system up), and then it will drop back down to the normal 5% CPU usage. 
    I had always thought it had something to do with Firefox, but I had Firefox closed while I was away at work today, and yet when I come home and wake my computer up my CPU usage graph shows that it's been at a solid 25% all day long. 
    Anyone have any ideas what this might be, or recommend a way to hunt down exactly what process is eating my CPU cycles while the display is off?
    Thanks a lot, this has been puzzling me for some time now.
    EDIT: I should add that I am running KDE, and have been on the other distros as well (to the best of my recollection).  After realizing this it seems like this thread may be better suited for the Applications & DE forum, but I'm not sure... it could very well be something to do with the kernel or something to do with power saving.  Please move if you see fit.

    The CPU usage is not accounted for in the system monitor app.  There's roughly 4% usage accounted for, yet there's a total of 29% being used.
    The script doesn't seem to find anything either.  High idle CPU usage kicks in maybe 3/4 of the way through, but the output doesn't seem to change from the beginning at all.

  • High CPU usage while buffering a video

    I have a high CPU usage (over 40%) while only buffering this video.

    a) open this url: http://www.wimp.com/marsearth/
    b) pause the video if it starts automatically
    c) use task manager or process explorer to view the cpu/gpu usage
    reproducible: mostly

    While we're aware of the issue, there's not much we can do about it.  The modern security realities facing web browsers have made sandboxing a necessity. 
    There's a good explanation of what's happening here: http://blogs.adobe.com/asset/2012/06/inside-flash-player-protected-mode-for-firefox.html
    Long story short, each video packet has to be passed from the browser to a medium-integrity broker process, then to the low-integrity flash player process for rendering.  If an attacker manages to hijack the Flash Player thread, the process is low-integrity, which prevents the attacker from doing much with it.  While it's not an absolute guarantee (nothing in security is), it raises the bar significantly for attackers.
    The downside is that all of that extra message-passing consumes CPU cycles, especially if you're trying to fill an exceptionally large buffer as fast as possible.  There's not a lot of opportunity to optimize this.
    If you're fine with the risk, you can manually disable ProtectedMode on your machine.  If you're only dealing with trusted sites, and you're not doing anything critical with the machine (work, banking, etc), then it's probably not a huge deal.
    Ultimately, ProtectedMode is like a vaccine -- it's a herd-immunity thing.  If the majority of people run it, exploits targeting machines without it are inconsistent and probably not worth pursuing when you look at the effort involved in developing an end-to-end exploit.  If a large number of people disable it, it becomes economically attractive for people building botnets, and you'll have a problem if you're not using it.
    To disable Protected Mode, add the following line to your mms.cfg file located in:
    Windows 32bit: C:\windows\system32\macromed\flash
    Windows 64bit: C:\windows\syswow64\macromed\flash
    ProtectedMode=0
    If the mms.cfg file does not exist, create one using any standard text editor (e.g.. notepad)
    Depending on your operating system, you might need to first save the mms.cfg file to a writable location (such as your documents or desktop folder) and then copy the file into the destination folder using Windows Explorer.
    To re-enable Protected Mode, simply remove the line from the mms.cfg file.

  • Kernel_task taking up to 800% CPU Usage

    My macbook has become extremely slow lately that it's almost impossible to get work done. I've observed the Activity Monitor and realized the "kernel_task" process has been eating up most of the the CPU usage with usually 200%-300% but can reach as high as more than 800%. I've looked the problem up on the internet and found that others have solved this problem by deleting a certain .plist file. However, that solution doesn't seem to apply to me as my mac's model identifier is MacBookPro9,2 and thus doesn't have the corresponding file that needs to be deleted.
    I've been going all over the internet and even a mac store trying to look for a solution but it seems I've hit a roadblock. I've become desperate for help that I've chosen to post here for the first time hoping to get your help and advice. Thank you for your time and patience.
    Here are some details that might shed some light on the issue:

  • Kernel Task over 400% CPU usage

    Hello, I have some questions about the Kernel Task in my activity monitor.
    Recently, after a hard disk failure, I have my Macbook Pro wiped and start afresh with Mavericks. All was well, but it slowed down tremendously in the last couple of days. I checked the activity monitor and Kernel Task is always around 400-470%, sometimes it even peaked to 1000+%! I closed all my applications but it is still taking up all my RAM. I cannot work when it is freezing up every 2 seconds. What is the problem?
    Here is the report, if it helps:

    The kernel is using excessive processor cycles. Below are some possible causes for the condition.
    Throttling
    When it gets high temperature readings from the hardware, or a low-voltage reading from the battery, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
    ☞ a buildup of dust on the logic board
    ☞ high ambient temperature
    ☞ a worn-out or faulty battery in a portable
    ☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
    Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
    If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on battery power, the fault is in the battery or the logic board. If it happens only on AC power, charging is causing the machine to heat up. That may be normal on some models. CPU usage should drop when charging is complete.
    Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
    If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
    Installed software
    User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
    Corrupt NVRAM or SMC data
    Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
    External display
    Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

  • 10.6.8 randomly freezing, CPU usage goes to 200% and never reduces

    Hi everyone,
    I have a Macbook running 10.6.8 and in my account, there are random times where CPU usage spikes, applications cannot be launched, and killing various processes causes them to spike right after relaunch. It almost always seem to have one of Google Software Update, pbs, or plugin-container in the list of processes taking up all of my CPU (eg. 70% Finder, 70% PBS, 60% Activity Monitor). If I kill all of those processes, when Finder relaunches it goes back to a huge amount of load and no responsiveness. Oddly enough, I can still use Quicksilver and occasionally Firefox when this occurs.
    I'm only ever running Firefox and Quicksilver and never had these issues before.
    I've verified & repaired permissions and verified the disk to no avail.
    Would anyone please be able to help? When it happens, I have no choice but to restart the computer by holding down the power button because it won't respond for 20minutes + when I tried leaving it alone.
    When I ran the 10.6.8 update last week it say Flashback was removed; I'm hoping this isn't related to some sort of malware....

    It most certainly is or was malware. A Backdoor Trojan, to be exact.  Make sure you have installed everything that Software Update recommended as there were some subsequent updates to Java which will prevent you from being re-infected and I highly recommend you don't wait so long to update in the future.  Then disable Java (not JavaScript) in your browsers so as not to become infected when the next vulnerability is exploited.
    I don't think any of your current problems are related to Flashback, especially since it informed you that it had been removed. The symptoms were redirection of your browser to advertising sites and crashes of various applications, mostly Safari.
    Hopefully somebody else will come along with some ideas about CPU usage.

  • 100% CPU usage during downloads in iTunes 7

    Wow, ever since I installed iTunes 7, my CPU stays pegged at almost 100% utilization during iTunes downloads. Downloading podcasts, songs, video, etc. all cause the CPU usage spike.
    Running 2.26 Ghz P4 with 1 Gb RAM, 200 GB HD.
    Even when I'm only getting about 200K/sec in data, CPU is pegged. Machine becomes very sluggish. Once the download is complete, CPU usage goes back to close to 1-3%.
    Any ideas?
    Dell Dimension 2400   Windows XP Pro   Mac Mini PowerPC

    I had to revert back to version 6.05. iTunes 7 on XP is unusable. I used to browse the web and do other productive things while my podcasts were downloading. Now the CPU is pegged so high, that I can barely get the machine to respond.
    I installed iTunes 7 on my 1.42 GHz Power PC Mac Mini with only 512 Mb RAM. Downloading 3 large video podcasts at one time only pushes the CPU to 60%. One large download is around 20%. The machine is totally usable while downloading.
    Looks like they got the Mac OS X version right and the XP version way wrong!
    I'm sticking with version 6.05 on XP until they can fix these usability issues.
