One of my machines has become incredibly slow and must have something infecting it. One of you walked me through the steps on another machine a few months back with amazing results. Can I get an Expert to walk me through this one? I'm a very proficient computer user.

Hi hrolsons,

Let's run a few things and see how much deeper we need to look.

Scan for Spyware/Adware

The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware Free version and save it to your desktop.

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.


alternate download link 1
alternate download link 2

  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.

MBAM will automatically start and you will be asked to update the program before performing a scan.

  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.

On the Scanner tab:

  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.

Back at the main Scanner screen:

  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.

Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs
---------------------------
Be sure to re-enable your AV and malware scan tools if they were disabled


SAS, may take a long time to scan
Please download and scan with SUPERAntiSpyware Free

  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
  • First

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:

  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.


Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

I will run what you suggested. I'm using another machine to download the programs because the internet on the infected machine is at almost a standstill. I've switched the Ethernet cord to one that is for sure working perfectly and the internet is unaffected.

HI hrolsons,

Ok. Those two came out clean, let's have a look with a few more.

Please download GMER from one of the following locations and save it to your desktop:

* Main Mirror
This version will download a randomly named file (Recommended)
* Zipped Mirror
This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.

* Disconnect from the Internet and close all running programs.
* Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
* Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
* Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.
Posted Image

* GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
* If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
* Now click the Scan button. If you see a rootkit warning window, click OK.
* When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
* Click the Copy button and paste the results into your next reply.
* Exit GMER and re-enable all active protection when done.

-- If you encounter any problems, try running GMER in Safe Mode.

Please perform a scan with Eset Onlinescan (NOD32).
(Requires Internet Explorer to work. If given the option, choose "Quarantine" instead of delete.)
Vista Users be sure to run Internet Explorer as Administrator. To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select "Run as Administrator" from the context menu.

  • You will see the Terms of Use. Tick the check-box in front of YES, I accept the Terms of Use
  • Now click Start.
  • You may receive an alert on the address bar that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then Click Install ActiveX component.
  • A new window will appear asking "Do you want to install this software?" (OnlineScanner.cab)".
  • Answer Yes to install and download the ActiveX controls that allows the scan to run.
  • Click Start.(the Onlinescanner will now prepare itself for running on your pc)
  • To do a full-scan, check: "Remove found threats" and "Scan potentially unwanted applications"
  • Press Scan to start the online scan. (this could take some time to complete)
  • When the scan has finished, it will show a screen with two tabs "overview" and "details" and the option to get information or buy software. Just close the window.
  • Now click Start > Run... > type: C:\Program Files\Eset\EsetOnlineScanner\log.txt
  • The scan results will open in Notepad.
  • Copy and paste the log results in your next reply.

Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn\ them back on after you are finished

GMER was clean, and ESET is probably going to take all day to scan it's going so slow.

Here is the computer, but I'm not seeing a manufacturer for the hd:

I'll keep looking, and if need be, take the cover off.

Hi hrolsons,

Click on Start then Run.

In the Run box type: devmgmt.msc
and press enter.

You will now see the device manager.

Click the Plus next to Disk Drives. You should now see a model number for your hard drive.

Can you give me that model number?

From the model number I can tell you what hard drive you have and what testing utility to use.

Thank you for that tip:

WDC WD64 00AAKS-65Z7B0

As I've been analyzing this machine, it seems as though something must be wrong with the internet only. I've tried switching the ethernet cable to a known good one and it is still very very slow. The LAN speed is fine, it seems to just be anything Internet related. I uninstalled my virus software(ESET NOD32) just to be sure it wasn't causing the trouble, to no avail.

Hi hrolsons,

Although I'm not thinking you have a problem with your drive now after hearing about the internet speed being an issue, I'm still going to ask you to test your drive.

I've found this information about your drive that has all of the drives specifications.

I'd like you to go here and download and run the Western Digital Data Lifeguard Diagnostics. You can use the windows version or the DOS ( CD ) version.

I recommend the CD version as it loads by itself from CD and has no other software involved while testing.

Download the ISO image and burn the image to CD. Once burned, reboot your computer and boot from the just burned CD.

I recommend running both the Quick Test and the Extended Test for better results.

As for your internet connection, we can try resetting both TCP/IP and your Winsock.

Before doing so, I recommend you reinstall NOD32 and allow it to update.

We will be resetting both TCP/IP and Winsock on your computer to help with your troubles.
To successfully complete this, you will need to be at a command prompt.
Click on Start then Run. In the Run box type CMD and press enter.
You will now see a black window with one line of text and a blinking cursor.

You will next type:

  • netsh int ip reset tcp.log

This will reset your TCP/IP settings.

Next you will reset Winsock:

You will type:

  • netsh winsock reset sock.log

When the Winsock is finished you will be directed to restart your computer. Type exit in the window and press enter.

From here you will do a normal restart on your computer and retest your network connection.

Please let me know the results of both the hard drive tests and your internet speed after running the reset procedures.
