Hello, my computer was twice infected over the weekend with the zlob virus ( I cannot give you the exact details because I emptied the vault, but there were nine infections in total and 4 were critical). Since then I have repeatedly run antivirus program AVG and spybot which have gradually detected and removed a few more threats (they kept re-appearing) and I have scanned with ccleaner, Counterspy, and carried out all the scans that you requested - they now all report no threats detected. However, when I run these scans I can actually see a huge amount of Zlob files are still in the computer- many are codec files - and I'm unable to find these files to delete them. I am being prevented from installing a new Kaspersky disc, the computer instantly reports that it cannot find the installation program. I am also unable to use internet explorer as my default browser, the computer automatically sets it to another. Yesterday I noticed a new message at the bottom of the internet properties menu which reads, "Some settings are managed by your system administrator." I am the owner of this computer. I have re-installed windows xp sp2 three times but the problems persist. I am new to computers, have only had the internet for two months, but something is very wrong and I think that the damage is spreading.

Could you please advise me as to what I should do.

Thankyou.

Please print out and follow the generic instructions for using "SmitfraudFix". Make sure you scroll down to Clean and perform the steps where you reboot in "Safe Mode" and run option #2.
-- If you have downloaded SmitfraudFix previously, please delete that version and download it again as the tool is frequently updated!
-- If the tool fails to launch from the Desktop, please move smitfraudFix.exe to the root of the system drive (usually C:\), and run it from there.

Please download ATF Cleaner by Atribune & save it to your desktop. DO NOT use yet.
Please download and install SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here and unzip into the program's folder.)
  • Under the "Configuration and Preferences", click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and 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 a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "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 browser click Firefox 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.
  • If you use Opera browser click Opera 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.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • 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. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.

Hello Quieman7, thankyou for your swift response.

A brief post to let you know that I have been trying to conduct all tests since 12.pm, 1/2/08, but the computer will not allow me to go beyond anything other than the most basic of scans. I am unable to complete SmitFrauf Fix because the computer will not allow me to get past the "check for updates" stage." However, I am able to install and run the ATF cleaner and the Super AntiSpyware Free, only with this scan I was unable to check - "close browsers before scanning, scan for tracking cookies, terminate necessoary threats." because that screen did not appear. But I will persist. I have conducted each test in safe mode and have deleted and run through the new downloded programs four times. I have decided to disable system restore, reboot the system and retry. Please let me know If I am making an error.


Thankyou for you support on this.

"System Restore and malware removal - what is best practice?"

Try running SmitFraudFix in normal mode.

Then perform an Online Virus Scan like BitDefender.
(These require Internet Explorer to work. Watch the Address bar in IE. You may receive alerts that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then Click Install ActiveX component. If given the option, choose "Quarantine" instead of delete.)

Hello quitman7,
I have scanned with SmitFraud Fix in normal mode. Infected files were deleted and the registry cleaned but did not receive the prompt for "replace infected items" so saved the log to notepad and "Quit." Downloaded "Bit Defender Total Security 2008", updated it and ran a full scan:

Infected items:0
Suspect items:0
Hidden files:0
Hidden Processes:0 "No threats were found in the scanned folders."

Rebooted and checked for IE browser - not present, another home page instantly loaded. These posts are few and far between because I am continually losing internt connection; have to turn the computer off and let the memory clear etc. BitDefender reports that I am connected to another network!
Will wait to hear from you

thankyou.

[quotechecked for IE browser - not present, another home page instantly loaded[/quote]If the browser was not present, how did another page load? That doesn't make sense.

Some settings are managed by your system administrator. For more information, see Why won't Windows allow me to change a system setting?. You can find more discussion about this if you do a Google search of that message.

Try resetting the IP address:
Go to Start > Run and type: cmd
Press OK or Hit Enter. A dos Window will appear.
At the commmand prompt type or copy/paste:: ipconfig /release
Hit Enter.
When the prompt comes back, type: ipconfig /renew
Hit Enter.
Close the command box and and see if that fixes the connection. No reboot needed.

Most Internet connectivity problems arise out of corrupt Winsock settings due to the installation of a networking software or Malware infestation. Check with your ISP provider first and if they insist that your connection is coming through, the problem must be at your end.

Hello quietman7,

I now have the internet explorer browser and have managed to install the Kaspersky antivirus program which has cleaned
up a few more infections. Although the zlob downloader files are no longer infected, is there any way to remove them
from the computer? I can see them clearly when I scan with Spybot but when I search through my documents,
my computer and hidden files they don't appear.

Thankyou.

Can you run smitfraudfix option #2 in safe mode now?
-- If the tool fails to launch from the Desktop, please move smitfraudFix.exe to the root of the system drive (usually C:\), and run it from there.

If not, can you provide the names of each file and the full path where they are located so we can try another removal tool.

Hello quietman7,
Have run SmitFraud Fix in safe mode but again, no option for replace deleted files. I don't have a printer so the only way
to see these files is when I run a scan with Spybot and I then jot the files down as quickly as I can. There do not appear to be any file paths, the only information I have is numeric, for example, 900050/109616 Smitfraud-C.generic. Here are some of the Zlob file names:

Zlob.KeyGenerator, Zlob.KeyCodec, Zlob.Commander, Zlob.SecurityTools, Zlob.JPEG-Encoder, Zlob.HomepageMonitor,
Zlob.PowerCodec, Zlob.Backdoor, Zlob.WinMediaCodec. Some of the Zlob.Downloaders include Zlob.cot, Zlob.rid,
Zlob.doc, Zlob.jot, Zlob.wot, Zlob.Elite, Zlob.vdt, Zlob.oid and so on.

Hope this is useful, thankyou.

This issue will require further investigation and probably the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a hijackthis log.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". You may have performed some of these steps already. If you can't perform a step, then skip and continue with the next. In step #9 there are instructions for downloading HijackThis and creating a log. (This is a self-extracting version which will automatically install the current version of HJT in the proper location.) If using Windows Vista, be sure to Run As Administrator.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.
