After a recent "cleanup" from a maleware infestation, I installed Avira Antivir and it helped clean up a lot of the mess. I have let this application run it's guard process in the background and about every 10 minutes or so it let's me know the following:

Virus or unwanted program 'TR/Crypt.XDR.Gen [trojan]'
detected in file 'C:\WINDOWS\Temp\uycb.tmp\svchost.exe.
Action performed: Deny access

It appears that Avira is catching this process before it has a chance to cause any more trouble, but I would like to get to the root of it and eliminate it all together if possible.

Additionally, I have it scheduled to perform a daily scan. After last nights scan it also found instances of this:

Virus or unwanted program 'HTML/Infected.WebPage.Gen [virus]'
detected in file 'C:\Documents and Settings\NetworkService\Local Settings\Temporary Internet Files\Content.IE5\1YE2BNNR\build_creative[1].htm.
Action performed: Deny access

I run XP Pro SP2. Is there anyone that has experienced this problem that may be willing to assist? I look forward to hearing back from you soon.

Hello, please run these tools next.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.alternate download link 1
alternate download link 2
MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.
Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
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 yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
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.

Thank you for your help. I really appreciate it.

I ran MalwareBytes and it found no results. Below is the scan log for your reference:

I was NOT able to get into safe mode but I ran ATF Cleaner and Super in normal mode. Super did find 3 instances of tracking cookies but that's about it. Log below:

The PC seems to be running fine, BUT, Avira AntiVir's Guard function keeps leaving me the same event notice every 10 - 15 minutes:

Virus or unwanted program 'TR/Crypt.XDR.Gen [trojan]'
detected in file 'C:\WINDOWS\Temp\uycb.tmp\svchost.exe.
Action performed: Deny access

Only differences on the notification is sometimes the action performed says allow access and others it says deny access. Also, the sub-directory is always a random 4 character string.tmp but the path's are otherwise the same.

Next step?

Hello, not having safe mode is an important issue.
SUPERAntiSypware has a built in "Repairs" feature to fix policy restrictions and certain Windows settings which are sometimes targeted by malware infection. To use this feature, launch SUPERAntiSypware.
  • Click the Repairs tab.
  • Click on (highlight) "Repair broken SafeBoot key" and then click the Repair button.
  • You may be asked to reboot your computer for the changes to take effect.

Thanks again. Sorry for the delay in response. It's not that I am unable to boot to safe mode it's that my network login does not grant me access to safe mode with my current credentials. Does that make sense or do you feel it could be the malware that is causing this?

I'd like to be sure as a a safe mode issue is very serious as I said.. So let's be sure and get a better look in here.

Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Let me know if that went well.

Thanks for all of your assistance. The problem has been resolved. Please close out this thread. It appears that Avira was finally able to successfully quarantine and remove the infected files. No other instances of this bug have been found in several subsequent scans and the guard functionality of Avira no longer recognizes it as a threat. PC is running smoothly with no issues. Not being able to login while in safe mode is a restriction our company's system admin has put into place.

The file 'C:\Documents and Settings\All Users\Application Data\Adobe\sp.DLL'
contained a virus or unwanted program 'TR/Crypt.XDR.Gen' [trojan]
Action(s) taken:
The registration entry <HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved\{96AFBE69-C3B0-4b00-8578-D933D2896EE2}> was removed successfully.
The registration entry <HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers\sp\> was removed successfully.
An error has occurred and the file was not deleted. ErrorID: 26003.
The file could not be deleted!
Attempting to perform action using the ARK library.
The file was moved to the quarantine directory under the name '568bec1e.qua'.
The registration entry <HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved\{96AFBE69-C3B0-4b00-8578-D933D2896EE2}> was removed successfully.
The registration entry <HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers\sp\> was removed successfully.

Great news!!
Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.

Done and Done. Thanks again for guiding me through this. Not sure what in the process we did that allowed Avira to all of a sudden be able to quarantine and/or remove those files. The only thing I varied from my routine was shutting off the PC and disconnecting the ethernet cable when I left for the weekend. When I returned today I updated the Avira definitions and ran a scan and voila, all clean.

It is hard to say. Sometimes it is best to disconnect when scanning. Sometimes you need to scan in both safe and Normal mode. New malwares are more resilient. Sometimes it tkaes several tools as here.

You're welcome from all of us here at BC. We are glad to have helped.
Please take a few minutes to read our quietman7's excellent Tips to protect yourself against malware and reduce the potential for re-infection:,in post 17. :thumbsup:
