Yet anorher 'MALICIOUS URL BLOCKED' case...

[TopsyT]

avast Network Shield has been popping up approx. every 60-90 seconds. The fhree that come up most often are: onceagaincrap.com/z/, yetanothersheet.com, and 85.195.92.10/z/. All of them show the associated process as: c:\WINDOWS\System32\svchost.exe. I believe the problems started when I initiated an avast full system scan and it found 16 JS:ScriptIP-inf Trojans, which it quarantined. I have scanned a number of times with MBAM with nothing found, as well as a few others w/ no visible results. My Windows XP system has gotten so erratic, I really need expert help, please!

Thank You, TopsyT

OK lets re-run TDSSKiller first ...  whilst I look at the log

Download the latest version of TDSSKiller from here and save it to your Desktop.
 
 

• Doubleclick on TDSSKiller.exe to run the application
  
  
  
• Then click on Change parameters.
   
  
   
  
• Check the boxes beside Verify Driver Digital Signature and Detect TDLFS file system, then click OK.
   
  
• Click the Start Scan button.
   
   
  
• If a suspicious object is detected, the default action will be Skip, click on Continue.
   
  
   
  
• If malicious objects are found, they will show in the Scan results and offer three (3) options.
• Ensure Cure is selected, then click Continue => Reboot now to finish the cleaning process.
  
  
• Get the report by selecting Reports

 

• Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.

Hi....Apologies for the extended time to reply to your last post, essexboy...I had to deal w/ unrelated family issues. Anyways, I went ahead and followed evrything u said, up until the last step of 'copying/pasting log in next reply'...Well once log window came up, clicking right mouse button to bring up context menu did nothing, and could not find a way to save or copy TDSSKilller log. Ohyeah,...Upon exiting TDSSKiller log window, and ran the fixes for all detected malicious/suspicious objects, and after exiting that program, Avast started popping up a few times showing rootkits were detected/found! so I did go straightaway into my Avast Virus Vault, and listed were 5 rootkits, and 1 Win32 malware object. I will list all 6 below:

Win32:Alureon-MJ@mbr [Rtk]
Win32:Malware-gen
Win32:Alureon-AUV [Rtk]
Win32:Rootkit-gen [Rtk]
Win32:Rootkit-gen [Rtk]
Win64:Alureon-B@mbr [Rtk]

Thanks, Trent

The TDSSKIller log should be located at C:\TDSSKiller date time
Please attach that log

[TopsyT]

Here is the requested log from TDSSKiller.. it was located exactly where you said it would be!

[essexboy]

OK re-run TDSSKiller with the same parameters
When you get to this part select delete:

\Device\Harddisk0\DR0 ( TDSS File System )

Avast will alert as the files are being moved.

Once done could you let me know what problems remain

[TopsyT]

Hi...Re-ran TDSSKiller, Avast alerted and moved it. Have been using the compter for some hours now, and everything is looking good so far  :::crosses fingers::: I really appreciate all your help!

Subject to no further problems   

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Run OTL

• Under the Custom Scans/Fixes box at the bottom, paste in the following
  

  :Commands
  [resethosts]
  [emptytemp]
  [CLEARALLRESTOREPOINTS]
   [Reboot]

• Then click the Run Fix button at the top
  
• Let the program run unhindered, reboot the PC when it is done

Run OTL and hit the cleanup button.  It will remove all the programmes we have used plus itself. 

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

• Click Start.
• Open My Computer.
• Select the Tools menu and click Folder Options.
• Select the View Tab.
• Under the Hidden files and folders heading select Do not show hidden files and folders.
  
• Click Yes to confirm.
• Click OK.

   Your Java is out of date.

Please follow these steps to remove older version of Java components and upgrade the application.

 Upgrading Java:
