    Ubuntu slow

    This happens some times when I am in Firefox and doing something in Libreoffice computer slows
    down after a while the page where I am greys up the Hard Disk led keeps flashing meaning
    hard disk action, stays on these conditions until restart computer. Other times just going Dash Home and open an application takes long time, an window opens with “Sorry, Ubuntu 12.04 has experienced an internal error”
    Thinking what could be the fault and has I have Clamtk I decide to scan, on the end got an long report
    wish as 57 files all infected with PUA.win32 (this is for Windows) Windows with Virtualbox only, the report has Quarantine and Delete, dint click nothing but try to copy as usual but cant be copied, so I decide to ask for help, I think this is the reason for Ubuntu problem. What should I do to clean this files and computer?
    Thank you

    My worry is the first group, the kyo.zip I can delete it Windows game for my wife
    but the rest are quite important I ask again how to clean this from hard disk. This is
    one of the very top reasons I gave up Windows, after I read much how good Ubuntu
    is about this subject, I am on the some boat.
    I receive notification having 29 files Update Ubuntu, must I carry-on with this update
    with all this virus?
    I appreciate if some could supply this answers.
    Thank you

    I don't think virus in windows files will have any affect on Ubuntu (can anyone please confirm this)

    According to this wiki page, your system requirements are fine, but even with 3GB RAM I feel lag while using Unity 3D. Since your RAM is pretty low, I'll suggest you to try Ubuntu 2D (you can choose it before entering password on Login Screen).

    If you still feel lag and slow system, try installing XFCE4 and LXDE as your desktop environments, you'll surely see some improvements. (try XFCE4 first)

    Also Please don't install lubuntu-desktop or xubuntu-desktop instead of LXDE and XFCE4.
    Please install plain-vanilla lxde and xfce4
    To install LXDE:
    Code:
    sudo apt-get install lxde
    To install xfce4:
    Code:
    sudo apt-get install xfce4

    -G41M-Combo:~$ lspci | grep VGA
    00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)

    Should I install the waiting Ubuntu update?
    Thank you

    Yes, it can't hurt.

    Also, you do not have a virus on Ubuntu. Maybe on Windows, but it won't affect Ubuntu. Also, viruses rarely cause slowdown even on Windows.

    Have you checked the SMART statistics for your hard disk? Open the Disk Utility program and click on your disk, then click SMART Data. Any little red lights indicate a problem.

    If there's no problems reported there, you could try running IOtop. In the terminal, type:

    Code:
    sudo apt-get install iotop
    sudo iotop
    When you start having the problems where the disk is being used a lot and the windows go grey, have a look at the window where IOtop is running, and see if there's a program consistently at the top of the list DURING THE PROBLEM. If there is, then please let us know what it is.

    To quit IOtop, press Q or close that window.

    You could also run Memtest from the GRUB boot menu to check your RAM. Run it for eight hours. If there are any errors, any errors at all, you have bad RAM that may be causing the problem.
    I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.

    Re: Ubuntu slow

    Since you have just 1GB of RAM, it could also be that the system starts to use swap a lot, especially when you run such memory hungry applications as Firefox and LibreOffice at the same time.

    Try running this in terminal when your system begins to slow down to see how much memory is used and if it uses swap:
    Code:
    free -m

    Re: Ubuntu slow

    Thank you 3rdalbum and Laobi for your responses.
    To 3rdalbum
    I did checked SMART immediately and the results are:
    Self Assessment: Passed
    Self-tests: Completed OK
    Power cycles: 3012
    Bad Sectors: (Green) Disk is healthy.
    The list compromise of:
    Some with green, others with black N/A.
    I got more adventure and Run Self-test
    Choose Short (default)
    After starting to run it stopped with red X Cancel Self-test
    I dint install iotop yet first send this to you.
    To I will free -m after this, another clever idea.


    Again Thank you very munch.
