Hello Sam and welcome to Geeks to Go

As an introduction, please note that I am not Superhuman, I do not know everything, but what I do know has taken me years to learn. I am happy to pass on this information to you, but please bear in mind that I am also fallible.

Please note that you should have Administrator rights to perform the fixes. Also note that multiple identity PC’s (family PC’s) present a different problem; please tell me if your PC has more than one individual’s setting.

Before we get underway, you may wish to print these instructions for easy reference during the fix, although please be aware that many of the required URLs are hyperlinks in the red names shown on your screen. Part of the fix may require you to be in Safe Mode, which may not allow you to access the internet, or my instructions!

You have quite a mixture of malware and Trojans that need to be eradicated. I am going to include the rdriv fix in this, in an attempt to save time. Let’s see what we can do with the first sweep.

I note that you are running HijackThis from Temporary Desktop; please create a new folder for it (for example C:\Program Files\Hijackthis\Hijackthis.exe) and move the programme into it. It is very important you do this before anything else since backup files can be deleted if they are not within their own folder!

To start please download the following programmes, we will run them later. Please save them to a place that you will remember, I suggest the Desktop:

Killbox by Option^Explicit
CCleaner
Ewido Security Suite

Go to Start>Run and type Services.msc then hit OK
Scroll down and find this service:

UDP Sub Packet Classifier (UDPSPC)

When you find it, double-click on it. In the next window that opens, click the Stop button, then click on Properties and under the General Tab, change the Startup Type to Disabled. Now hit Apply and then OK.

Run HiJackThis. Click on None of the above, just start the program. Now, click on the Config button (bottom right), then click on Misc Tools, then click on Delete an NT Service a window will pop up. Enter this item into that field (copy and paste):

UDPSPC

Click OK.

It should pull up information about the service, when it asks if you want to reboot now click YES

Install Ewido Security Suite.
  • Install Ewido security suite
  • When installing, under "Additional Options" uncheck..
    • Install background guard
    • Install scan via context menu
    • You will need to update Ewido to the latest definition files.
    • On the left hand side of the main screen click update.
    • Then click on Start Update.
  • The update will start and a progress bar will show the updates being installed.
    (the status bar at the bottom will display "Update successful")
If you are having problems with the updater, you can use this link to manually update ewido.
ewido manual updates
Do NOT run a scan yet.

Next, please reboot your computer in Safe Mode by doing the following:
1) Restart your computer
2) After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
3) Instead of Windows loading as normal, a menu should appear
4) Select the first option, to run Windows in Safe Mode.

For additional help in booting into Safe Mode, see the following site:

Safe Mode

Launch Ewido, there should be an icon on your desktop, double-click it.
  • The programme will now open to the main screen.
  • When you run Ewido for the first time, you will get a warning "Database could not be found!". Click OK. We will fix this in a moment.
Now that the updates have been installed do the following:
  • Click on scanner
  • Click on Complete System Scan and the scan will begin.
  • NOTE: During some scans with Ewido it is finding cases of false positives.
    • You will need to step through the process of cleaning files one-by-one.
    • If ewido detects a file you KNOW to be legitimate, select none as the action.
    • DO NOT select "Perform action on all infections"
    • If you are unsure of any entry found select none for now.
  • Once the scan has completed, there will be a button located on the bottom of the screen named Save report
  • Click Save report.
  • Save the report .txt file to your desktop and include it in your reply.
Now close Ewido security suite.

Remain in safe mode.

Go to Start > Run type in:

cmd

Click OK.

A black window will open up.

Copy the below line, exactly, and paste it into the black window:

attrib -h -r -s C:\WINDOWS\system32\rdriv.sys

Hit Enter.

When it goes to the next line, copy the line below, exactly, and paste it into the black window:

del C:\WINDOWS\system32\rdriv.sys

Hit Enter.

Then type exit

Please re-open HiJackThis and scan. Check the boxes next to all the entries listed below.

O4 - HKLM\..\Run: [Microsoft Crs Fix Serv] wincrs.exe
O4 - HKLM\..\Run: [Microsoft U] wuamkopxp.exe
O4 - HKLM\..\Run: [Service Monitor] filen.exe
O4 - HKLM\..\Run: [Microsoftx U] winupdatexp.exe
O4 - HKLM\..\Run: [ Directory Manager Subsystem] dmss.exe
O4 - HKLM\..\RunServices: [Microsoft Crs Fix Serv] wincrs.exe
O4 - HKLM\..\RunServices: [Microsoft U] wuamkopxp.exe
O4 - HKLM\..\RunServices: [Service Monitor] filen.exe
O4 - HKLM\..\RunServices: [Microsoftx U] winupdatexp.exe
O4 - HKCU\..\Run: [Microsoft Crs Fix Serv] wincrs.exe
O4 - HKCU\..\RunOnce: [ Directory Manager Subsystem] dmss.exe
O23 - Service: UDP Sub Packet Classifier (UDPSPC) - Unknown owner - C:\WINDOWS\msudpspc.exe

Now close all windows other than HiJackThis, then click Fix Checked. Please now reboot normally.

RIGHT-CLICK HERE and Save As (in Internet Explorer, it's "Save Target As") in order to download the fixrdriv.reg file. Save it to your Desktop.

Locate fixrdriv.reg on your Desktop and double-click on it. When it asks if you want to merge with the registry, click YES.

After the "merged successfully" prompt, please do the following

Please install Killbox by Option^Explicit.

*Extract the programme to your desktop and double-click on its folder, then double-click on Killbox.exe to start the programme.
*In the Killbox programme, select the Delete on Reboot option.
*Copy the file names below to the clipboard by highlighting them and pressing Control-C:

C:\WINDOWS\system32\rdriv.sys
C:\WINDOWS\ItunesMusic.exe
C:\WINDOWS\wkssvc.exe
C:\WINDOWS\System32\wuamkopxp.exe
C:\WINDOWS\System32\filen.exe
C:\WINDOWS\System32\dmss.exe
wincrs.exe
wuamkopxp.exe
filen.exe
winupdatexp.exe
dmss.exe
C:\WINDOWS\msudpspc.exe


*Return to Killbox, go to the File menu, and choose "Paste from Clipboard".

*Click the red-and-white "Delete File" button. Click "Yes" at the Delete on Reboot prompt. Click "Yes" at the reboot now prompt..

If you receive a message such as: "Component 'MsComCtl.ocx' or one of its dependencies not correctly registered: a file is missing or invalid." when trying to run TheKillbox, click download and run missingfilesetup.exe. Then try TheKillbox again.

There is almost certainly bound to be some junk (leftover bits and pieces) on your system that is doing nothing but taking up space. I would recommend that you run CCleaner. Install it, update it, check the default setting in the left-hand pane, Analyze, Run Cleaner. You may be fairly surprised by how much it finds. Also click Issues then Scan for issues – fix selected issues

Then, run this online virus scan:
ActiveScan

Save the results from ActiveScan.

I need you to post the log from Ewido, the log from ActiveScan, and a new HiJackThis log into this topic.

Thanks for taking the time to reply to my topic :tazz:.

I'll follow your instructions and post back in a bit. I've tried to run the Panda online scan before, and it seems to producesome kind of javascript error whenever I try and scan one of my drives.

Congratulations! your new log is clean. :tazz: Just a little bit more to do to prevent further infection.

Reset and Re-enable your System Restore to remove bad files that have been backed up by Windows. The files in System Restore are protected to prevent any programmes changing them. This is the only way to clean these files: (You will lose all previous restore points which are likely to be infected.)

To reset your restore points, please note that you will need to log into your computer with an account which has full administrator access. You will know if the account has administrator access because you will be able to see the System Restore tab. If the tab is missing, you are logged in under a limited account.

(Windows XP)
1. Turn off System Restore.On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
Check Turn off System Restore.
Click Apply, and then click OK.
2. Reboot.

3. Turn ON System Restore.On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
UN-Check *Turn off System Restore*.
Click Apply, and then click OK.
MOST IMPORTANT: You should update Windows and Internet Explorer to get all the Latest Security Patches to protect your computer from the malware that is around on the internet.

I recommend going to the following link and update as recommended by Microsoft. This adds more security and extra features including a pop-up blocker for Internet Explorer. Microsoft Update

Now that everything is fixed, I suggest that you consider getting these programmes to help keep the computer clean:

SPYWARE BLASTER - Blocks bad ActiveX items from installing on your computer.
AD-AWARE PERSONAL – A fine free malware detector and removal programme
SPYBOT S&D – Excellent free spyware detector and removal programme
GOOGLE TOOLBAR - Blocks many unwanted pop-ups in Internet Explorer.
FIREFOX - Safer alternative to the Internet Explorer web browser.
AVG ANTIVIRUS - Free antivirus programme if you currently are not using one.
ZONEALARM - Free firewall programme if you currently are not using one.

Remember to update these frequently.

Please note that whilst there is nothing wrong in having more than one spyware detector/prevention programmes for “on demand” scanning, having two or more antivirus systems is not recommended as they may well interfere with each other.

You may also want to read "How did I get infected in the first place" to learn how to better secure your computer.

Be sure to keep Windows and your Anti-Virus updated. ;)

Happy safe surfing Sam"
