My computer runs the executable wscsvc32.exe and is a spoof of an anti-virus/spyware application.

I think I removed the malware. This did mess up my system, however. Delete: C:\windows\system32\wscsvc32.exe Delete All Content in: C:\Documents and Settings\\Local Settings\Temp

Hi and Welcome,

NOTE:
  • Malware removal is NOT instantaneous, most infections require several courses of action to completely eradicate.
  • Absence of symptoms does not always mean the computer is clean
  • Kindly follow my instructions in the order posted.
  • Please DO NOT run any scans or fix items without my direction.



Please do the following:

STEP #1

Please download DDS and save it to your desktop.
  • Disable any script blocking protection
  • Double click dds.pif to run the tool.
  • When done, two DDS.txt's will open.
  • Save both reports to your desktop.
—————————————————
Please include the contents of the following in your next reply:

DDS.txt
Attach.txt.



STEP #2


[external image: Posted Image]
Download GMER Rootkit Scanner from here or here.
  • Extract the contents of the zipped file to desktop.
  • Double click GMER.exe. If asked to allow gmer.sys driver to load, please consent .
  • If it gives you a warning about rootkit activity and asks if you want to run scan…click on NO.

    [external image: Posted Image]
    Click the image to enlarge it
  • In the right panel, you will see several boxes that have been checked. Uncheck the following …
    • Sections
    • IAT/EAT
    • Drives/Partition other than Systemdrive (typically C:\)
    • Show All (don't miss this one)
  • Then click the Scan button & wait for it to finish.
  • Once done click on the [Save..] button, and in the File name area, type in "Gmer.txt" or it will save as a .log file which cannot be uploaded to your post.
  • Save it where you can easily find it, such as your desktop, and attach it in reply.

**Caution**
Rootkit scans often produce false positives. Do NOT take any action on any "<— ROOKIT" entries

NOTE:
Please do not put your logs in code boxes

DDS

try this link,

malware may be blocking you as the other link worked fine for me.

If you cannot download DDS from this link, then please run this program, then continue on with the GMER scan as well:

  • Download OTL to your desktop.
  • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
  • When the window appears, underneath Output at the top change it to Minimal Output.
  • Check the boxes beside LOP Check and Purity Check.
  • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
  • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt.
    Note:These logs can be located in the OTL. folder on you C:\ drive if they fail to open automatically.
  • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post it with your next reply. You may need two posts to fit them both in.

I extracted gmer.exe but it will not "run". Nothing happens after I double-click it. I tried renaming it to gmer.bat but that was unsuccessful.
Post #7
Try it in safe mode.

To Enter Safemode
  • Go to Start> Shut off your Computer> Restart
  • As the computer starts to boot-up, Tap the F8 KEY repeatedly,
  • this will bring up a menu.
  • Use the Up and Down Arrow Keys to scroll up to Safemode
  • Then press the Enter Key on your Keyboard
  • go into your usual account

Hi,

Please do the following:

Download Combofix from either of the links below. You must rename it before saving it.
Save it to your desktop.

**Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved and renamed following this process directly to your desktop**

  • If you are using Firefox, make sure that your download settings are as follows:
  • Tools->Options->Main tab
  • Set to "Always ask me where to Save the files".

Link 1
Link 2

During the download, rename Combofix to Combo-Fix as follows:

[external image: Posted Image]
——————————————————————–
  • It is important you rename Combofix during the download, but not after.
  • Please do not rename Combofix to other names, but only to the one indicated.

———————————————————–

  • Double click on Combo-Fix.exe & follow the prompts.
    • When finished, it will produce a report for you.
    • Please post the "C:\Combo-Fix.txt" for further review.
    **Note: Do not mouseclick combo-fix's window while it's running. That may cause it to stall**


    ———————————————————–

  • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
  • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.

Here is the scan without the aforementioned setting. I'd like to mention that this is with a clean re-install of Windows XP Home Edition within the past 2-3 days.
