    Hi,
    I'm not able to find which process is causing the problem.
    I have an hp i7 with windows 7
    In the task manager I can see 80-99% cpu usage, but doesn't show which process is.
    If I don't use the pc for some minutes and start browsing everything is ok,
    cpu usage is normal and no lagging. After 5 minutes starts lagging and high cpu usage.
    I scanned with

    microsoft security essential
    avg
    trendmicro
    adaware
    malawarebyte
    spybot

    they cannot find where the problem is.

    here the hijackthis log


    thanks a lot for the help

    Between 17 and 25 May I went to Italy (I live in USA), and used pc only once.
    I used again the pc on 5/28 and all the problems started for no apparent reason
    On 28th I didnt installed-downloaded-run anything

    thanks for the help

    Your logs are clean. I suggest you follow up with this in the software forum.

    You need to put ComboFix directly on your desktop, or else the below will not work. You have it here:
    Running from: c:\users\Nazzareno\Downloads\ComboFix.exe


    If you are not having any other malware problems, it is time to do our final steps:

    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real time protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.We recommend them for doing backup scans when you suspect a malware infection.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.

    3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 of the READ ME
        for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    10. After doing the above, you should work thru the below link:


    Malware removal from a National Chain = $149
    Malware removal from MajorGeeks = $0

    Nothing to do,
    I uninstalled all the browsers, installed chrome that I never had before and the problem is the same.
    I think the problem is connected to browsers: programs works fine when the browsers are closed. When I open the browsers or 5 minute everything works ok, after starts the problems.
    I'll post on the software forums
