Hi R_Spec!

Welcome to Computer Cops!

First, clean out your Temp folders, then do a scan with Housecall followed by getting the updated version of HijackThis 1.98.1, and post another log.

How to delete all of your Temp files: http://www.personal-computer-tutor.com/deletingtempfiles.htm


Next, go to HouseCall Free Online Virus Scanner
and run the online virus scan. Right-click your AVG icon on the taskbar and turn it off before running this scan. Please select the Autoclean option when prompted.

From Computer Cops get the latest and greatist Direct-Download of HijackThis. It's zipped.

Save it to your download folder first.
Unzip the download (using a piece of software like Winzip). Create a folder in My Documents and unzip HijackThis into the new folder and run it from there. Do not run HijackThis from your desktop or a Temp folder as these do not allow HijackThis to save the changes it makes.

Post a fresh log here.

Best regards

Hi R_Spec!

You have an infamous hijacker known as "about:blank" but we do know how to fix this one. It can be a little complicated, but if you follow these instructions, step-by-step, we should be able to get you cleaned up.

First, much of this work will be meaningless if you do not get your security updates from Microsoft. You need at least SP1. Please go to this link and get it: http://support.microsoft.com/default.aspx?pr=winxp

Get Windows XP Service Pack 1 (3rd up from the bottom of the list).

Next, please follow these instructions carefully!

Download and install APM (Advanced Process Manipulation - freeware for NT4, 2K, XP.) from: http://www.diamondcs.com.au/index.php?page=apm

Close all windows except HijackThis and fix these lines:

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = file://C:\DOCUME~1\Des\LOCALS~1\Temp\sp.html

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = file://C:\DOCUME~1\Des\LOCALS~1\Temp\sp.html

R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Bar = file://C:\DOCUME~1\Des\LOCALS~1\Temp\sp.html

R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Page = file://C:\DOCUME~1\Des\LOCALS~1\Temp\sp.html

R1 - HKCU\Software\Microsoft\Internet Explorer\Search,SearchAssistant = file://C:\DOCUME~1\Des\LOCALS~1\Temp\sp.html

R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant = file://C:\DOCUME~1\Des\LOCALS~1\Temp\sp.html

R0 - HKLM\Software\Microsoft\Internet Explorer\Search,CustomizeSearch = about:blank

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,HomeOldSP = about:blank

R1 - HKLM\Software\Microsoft\Internet Explorer\Main,HomeOldSP = about:blank

O2 - BHO: (no name) - {2BEB79CB-9067-4CEB-AE5E-AA56DB7AE3B4} - C:\WINDOWS\System32\oncco.dll

Then start APM.
In the upper window select explorer.exe
In the lower window find and rightclick the BHO from the HijackThis log (should be O2 - BHO: (no name) - {2BEB79CB-9067-4CEB-AE5E-AA56DB7AE3B4} - C:\WINDOWS\System32\oncco.dll)
Select Unload DLL and click OK on the prompts that follow.

Reboot and scan with AdAware (update adaware first!) to remove the txt and html protocol association.

Configure Adaware as follows:

1. Download and install Adaware (free edition). (Click on "Adaware" in the left-hand column near the top at their website to download the free edition.)

2. After installing go to Start > Programs > Lavasoft and click on AdAware 6 to open the program

3. Look at the icons on the top right of the page and click on the ‘world’ and let AdAware update the spyware reference list (Note: Always update Adaware before you scan.)

4. Once the update is finished click on the ‘Gear’ icon (second from the left) to access the preferences/settings window

1. In the ‘General’ window make sure the following are selected:
· Automatically save log-file
· Automatically quarantine objects prior to removal
· Safe Mode (always request confirmation)

2. Click on the ‘Scanning’ button on the left and select :
· Scan Within Archives
· Scan Active Processes
· Scan Registry
· Deep Scan Registry
· Scan my IE favorites for banned URL’s
· Scan my Hosts file
· Under ‘Click here to select drives + folders’, choose:
· All of your hard drives

3. Click on the ‘Advanced’ button on the left and select:
· Include additional process information
· Include additional file information
· Include environment information
· Include additional object details

4. Click the ‘Tweak’ button and select:
· Under the ‘Scanning Engine’:
· Unload recognized processes during scanning
· Include basic Ad-aware settings in logfile
· Include additional Ad-aware settings in logfile
· Under the ‘Cleaning Engine’:
· Let Windows remove files in use at next reboot

5. Click on ‘Proceed’ to save the settings.

6. Click ‘Start’ and on the next screen choose ‘Activate in-depth Scan’ at the bottom of the page and then choose:
· Use Custom Scanning Options

7. Click ‘Next’ and AdAware will scan your hard drive(s) with the options you have selected.

8. Save the log file when it asks and fix all 'new objects' it finds.

9.) REBOOT


Please post a fresh HijackThis log.
