Computer running very slow. Video's dropping frames.

  1. Recently, I noticed video's would start droping frames very freequently. This would never happen before and it happened quite suddenly. Sinse then I've noticed a general drop in performance on my PC and when viewing task manager I've noticed a lot of cpu spikes going up to 20-60% when nothing is being used.

    I've included all three logs from "Viruses/Spyware/Malware, preliminary removal instructions" and followed all the steps exactly.

    A few things were detected but they seemed very minor. Although I wasn't having the worst problems to begin with.

    Hopefully there is nothing left and this will be smooth sailing.

    Thanks for your time.

    Ronok.

    I don't see much in the way of malware -

    Update your Java Runtime Environment
    • First try going to Start -> Control Panel -> double click Java
    • Select the Update Tab at the top of the Java console
    • Click the Check for Updates button at the bottom
    • If it finds the newer version (Java 6 Update 7) Follow the on screen instructions (uncheck the yahoo toolbar option)
    • After it installs the newest version Go back to Control Panel -> Add/remove programs (programs and features in vista)
    • Uninstall any older versions of Java

    If for some reason you couldn't update through the above instructions.
    Update your Java Runtime Environment
    • Click the following link
      Java Runtime Environment 6 Update 7
    • The 5th option down is the one you want (click Download)
    • Check the box to agree to terms of service
    • Check the box for your operating system and click 'Download selected'at the bottom
    • After the install Go to Start-> Control Panel-> add/remove programs (Programs and features), and uninstall any old versions
    • Navigate to C:\programfiles\Java -> delete any subfolders except the jre1.6.0_07 folder

    --------------------------------------------------------------------------------

    I would run kaspersky just to be sure - if all is good - I will give instructions to clean up

    Run Kaspersky Online AV Scanner

    Order to use it you have to use Internet Explorer.
    Go to Kaspersky and click the Accept button at the end of the page.

    Note for Internet Explorer 7 users: If at any time you have trouble with the accept button of the licence, click on the Zoom tool located at the right bottom of the IE window and set the zoom to 75 %. Once the license accepted, reset to 100%.
    • Read the Requirements and limitations before you click Accept.
    • Allow the ActiveX download if necessary.
    • Once the database has downloaded, click Next.
    • Click on "My Computer"
    • When the scan has completed, click Save Report As...
    • Enter a name for the file in the Filename: text box and then click the down arrow to the right of Save as type: and select text file (*.txt)
    • Click Save - by default the file will be saved to your Desktop, but you can change this if you wish.
    Attach the report into your next reply

    Thanks a lot for looking at this for me.

    I updated Java.

    The Kaspersky scan found a couple of threats.

    I would uninstall Mirc through add/remove programs

    OTMoveit2 by OldTimer
    Please download the OTMoveIt2 by OldTimer.
    • Save it to your desktop.
    • Please double-click OTMoveIt2.exe to run it. (Vista users, please right click on OTMoveit2.exe and select "Run as an Administrator")
    • Copy the file paths below to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose Copy):

      Code:
      [b]C:\Documents and Settings\conor\Local Settings\Application Data\Mozilla\Firefox\Profiles\62aiejz0.default\Cache\63329BDCd01
      C:\Program Files\mIRC[/b]
    • Return to OTMoveIt2, right click in the "Paste List of Files/Folders to Move" window (under the light Yellow bar) and choose Paste.
    • Click the red Moveit! button.
    • A log of files and folders moved will be created in the c:\_OTMoveIt\MovedFiles folder in the form of Date and Time (mmddyyyy_hhmmss.log). Please open this log in Notepad and post its contents in your next reply.
    • Close OTMoveIt2
    If a file or folder cannot be moved immediately you may be asked to reboot the machine to finish the move process. If you are asked to reboot the machine choose Yes.

    With the program launched click the green cleanup! button

    During that process I made the mistake of pressing cleanup before posting my next reply. It deleted the folder containing the log because of this.

    Uninstall Combofix
    * Click START then RUN
    * Now type Combofix /u in the runbox
    * Make sure there's a space between Combofix and /u
    * Then hit Enter.

    ---------------------------------------------------------------------------

    Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:
    1. Set correct settings for files
      • Click Start > My Computer > Tools menu (at top of page) > Folder Options > View tab.
      • Under "Hidden files and folders" if necessary select Do not show hidden files and folders.
      • If unchecked please check Hide protected operating system files (Recommended)
      • If necessary check "Display content of system folders"
      • If necessary Uncheck Hide file extensions for known file types.
      • Click OK

      clear system restore points

      • This is a good time to clear your existing system restore points and establish a new clean restore point:
        • Go to Start > All Programs > Accessories > System Tools > System Restore
        • Select Create a restore point, and Ok it.
        • Next, go to Start > Run and type in cleanmgr
        • Select the More options tab
        • Choose the option to clean up system restore and OK it.
        This will remove all restore points except the new one you just created.

    2. Make your Internet Explorer more secure - This can be done by following these simple instructions:
      1. From within Internet Explorer click on the Tools menu and then click on Options.
      2. Click once on the Security tab
      3. Click once on the Internet icon so it becomes highlighted.
      4. Click once on the Custom Level button.
        • Change the Download signed ActiveX controls to Prompt
        • Change the Download unsigned ActiveX controls to Disable
        • Change the Initialize and script ActiveX controls not marked as safe to Disable
        • Change the Installation of desktop items to Prompt
        • Change the Launching programs and files in an IFRAME to Prompt
        • Change the Navigate sub-frames across different domains to Prompt
        • When all these settings have been made, click on the OK button.
        • If it prompts you as to whether or not you want to save the settings, press the Yes button.
      5. Next press the Apply button and then the OK to exit the Internet Properties page.
    3. Use an AntiVirus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

      See this link for a listing of some online & their stand-alone antivirus programs:

      Virus, Spyware, and Malware Protection and Removal Resources

    4. Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

    5. Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

      For a tutorial on Firewalls and a listing of some available ones see the link below:

      Understanding and Using Firewalls

    6. Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.This is done in Vista through control panel -> windows updates.

    7. Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

      A tutorial on installing & using this product can be found here:

      Using SpywareBlaster to protect your computer from Spyware and Malware

    8. Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
    Follow this list and your potential for being infected again will reduce dramatically.

    here are some additional utilities that will enhance your safety

    • IE/Spyad <= IE/Spyad places over 4000 websites and domains in the IE Restricted list which will severely impair attempts to infect your system. It basically prevents any downloads (Cookies etc) from the sites listed, although you will still be able to connect to the sites.
    • MVPS Hosts file <= The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your coputer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer
    • Google Toolbar <= Get the free google toolbar to help stop pop up windows.
    • Winpatrol <= Download and install the free version of Winpatrol. a tutorial for this product is located here:
      Using Winpatrol to protect your computer from malicious software

    Thanks a lot for your help. :)

    I just have a few questions though:

    # If necessary check "Display content of system folders"
    # If necessary Uncheck Hide file extensions for known file types.

    I always thought it was best to hide the file extensions and not display the content of system folders. It seems I was misguided, what's the reasoning behind having them visible?

    I always have the windows firewall turned on. Would you recommend me using a different firewall or sticking with this one?

    Thanks again. :)

    The extensions for known file types is completely optional it doesn't make much of difference except for preference.

    however you are right on display content of system folders - I put it backwards
