I've been having trouble scanning my computer (XP SP3) using any antivirus programs. Both McAfee VirusScan and Malwarebytes begin the scan but then close after about 10 seconds-- no error messages or anything.

I tried the method of changing the .exe file listed here: http://www.bleepingcomputer.com/forums/top...ml#entry1368791

Unfortunatly this method doesn't work for me so i'm back to square one now. Any help would be appreciated =)

If you cannot run MBAM or complete a scan in normal mode, then try performing a Quick Scan in "safe mode".

Scanning with Malwarebytes Anti-Malware in safe or normal mode will work but removal functions are not as powerful in safe mode. MBAM is designed to be at full power when malware is running so safe mode is not necessary when using it. In fact, MBAM loses some effectiveness for detection & removal when used in safe mode because the program includes a special driver which does not work in safe mode. Further, scanning in safe mode prevents some types of malware from running so it may be missed during the detection process. Additionally, there are various types of malware infections which target the safeboot keyset so booting into safe mode is not always possible. For optimal removal, normal mode is recommended so it does not limit the abilities of MBAM but in some cases, there is no alternative but to do a safe mode scan. If that is the case, after completing a scan, it is recommended to uninstall MBAM, then reinstall it in normal mode and perform another Quick Scan.

When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

I appreciate the help!!

Unfortunatly, it just exited out of the Malwarebytes program even in safemode. Any other suggestions?

Also I just noticed that whenever i do a search on google or yahoo the link redirects me to a different site. Typing the webpage directly into the browser still works though. I'm not sure if that changes anything or not.

Please download TFC by Old Timer and save it to your desktop.
alternate download link
  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

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".

Scan with Dr.Web CureIt as follows:
  • Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to download the Full version Free Trial, just ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)
If you cannot boot into safe mode or complete a scan, then try doing it in normal mode. Be aware, this scan could take a long time to complete..

OK, I got TFC and Dr.Web CureIt. TFC ran fine, closed everything then taold me to restart. I restarted in Safe Mode and ran Dr.Web CureIt. The Express scan found one virus then prompted me to run a complete scan. I unchecked the Heurist Settings box and tried to scan but unfortunatly the scan stopped sortly after. Dr.Web CureIt starts "preparing for scan", looks through a bunch of files it appears then gets shutdown.

I restarted and tried again in regular mode but the same thing happened. TFC runs, Express Scan runs, Complete Scan gets shutdown.

The Dr.Web CureIt file was named cureit.exe and not something more random like you mentioned. Should I try renaming it some more random and try that procedure again? Or is there anything else I can do?

Thanks again for the help.

You used the alternate doenload link which does not rename the file. The primary one renames it randomly before downloading. Delete your version and redownload from the primary link I provided above or try this link:

Good news and bad news...

The good news: I redid everything below using the last link which randomized the DrWeb CureIt program. The safe mode scan completed and found:

57d8654.sys;c:\windows\system32\drivers;Trojan.Spambot.4489;Moved.;
57d8654.sys;C:\WINDOWS\system32\drivers;Trojan.Spambot.4489;Invalid path to file ;
57d8654.sys;c:\windows\system32\drivers;Trojan.Spambot.4489;Invalid path to file ;

It then prompted me to restart the computer to take effect.

The bad news: I tried scanning the computer again in normal mode to make sure everything was gone. The express scan worked fine but the complete scan exits before it actually starts scanning anthing (it just "prepares" for scanning then stops) like it did before. Also I still get redirects when i click links from google or yahoo so I know something is still there.

I used the TFC program again and restarted in safe mode. Rescanned it and got no error in the Express scan. When i tried the complete scan in safe mode again it closed.

Again, thank you for your help and patience with this.

Please download Sophos Anti-rootkit & save it to your desktop.
alternate download link
Note: If using the vendor's download site you will be asked to register with MySophos so an email containing an activation link can be sent to your email address.

Be sure to print out and read the Sophos Anti-Rookit User Manual and Release Notes.
  • Double-click sar_15_sfx.exe to begin the installation, read the license agreement and click Accept.
  • Allow the default location of C:\Program Files\Sophos\Sophos Anti-Rootkit and click Install.
  • A message will appear "Sophos Anti-Rootkit was successfully installed. Click 'yes' to start it now".
  • Click Yes and allow the driver and its randomly named .tmp file (i.e. F.tmp) to load if asked.
  • If the scan did not start automatically, make sure the following are checked:
    • Running processes
    • Windows Registry
    • Local Hard Drives
  • Click Start scan.
  • Sophos Anti-Rootkit will scan the selected areas and display any suspicious files in the upper panel.
  • When the scan is complete, a pop-up screen will appear with "Rootkit Scan Results". Click OK to continue.
  • Click on the suspicious file to display more information about it in the lower panel which also includes whether the item is recommended for removal.
    • Files tagged as Removable: No are not marked for removal and cannot be removed.
    • Files tagged as Removable: Yes (clean up recommended) are marked for removal by default.
    • Files tagged as Removable: Yes (but clean up not recommended) are not marked for removal because Sophos did not recognize them. These files will require further investigation.
  • Select only items recommended for removal, then click "Clean up checked items". You will be asked to confirm, click Yes.
  • A pop up window will appear advising the cleanup will finish when you restart your computer. Click Restart Now.
  • After reboot, a dialog box displays the files you selected for removal and the action taken.
  • Click Empty list and then click Continue to re-scan your computer a second time to ensure everything was cleaned.
  • When done, go to Start > Run and type or copy/paste: %temp%\sarscan.log
  • This should open the log from the rootkit scan. Please post this log in your next reply. If you have a problem, you can find sarscan.log in C:\Documents and Settings\\Local Settings\Temp\.
Important: Before performing an ARK scan it is recommended to do the following to ensure more accurate results and avoid common issues that may cause false detections.
  • Disconnect from the Internet or physically unplug you Internet cable connection.
  • Clean out your temporary files.
  • Close all open programs, scheduling/updating tasks and background processes that might activate during the scan including the screensaver.
  • Temporarily disable your anti-virus and real-time anti-spyware protection.
  • After starting the scan, do not use the computer until the scan has completed.
  • When finished, re-enable your anti-virus/anti-malware (or reboot) and then you can reconnect to the Internet.
Note: Not all hidden components detected by ARKs are malicious. It is normal for a Firewall, some Anti-virus and Anti-malware software (ProcessGuard, Prevx1, AVG AS), sandboxes, virtual machines and Host based Intrusion Prevention Systems (HIPS) to hook into the OS kernal/SSDT in order to protect your system. SSDT (System Service Descriptor Table) is a table that stores addresses of functions that are used by Windows. Both Legitimate programs and rootkits can hook into and alter this table. You should not be alarmed if you see any hidden entries created by legitimate programs after performing a scan.

Followed the directions in your last post and here is the log file:

all of the programs that Sophos found were "removable, but cleanup no recommended" so nothing really got cleaned. The three files listed under the Malwarebytes' folder were my attempts at renaming the malware.exe file so malware would run.

I attempted to run Dr.Web CureIt and like before the Express Scan runs, but the Complete Scan closes.

As I said, not all hidden components detected by ARKs are malicious. Its not unusal to find legitimate files mixed in with the bad. Sophos ARK does not recommend removal of files which the scanner does not recognize. However, that does not mean those files are all good and should be left alone. Further investigation is required after the initial scan to analyze and identify any malicious files which were detected.

This looks to be the problem entry:
Hidden: file C:\WINDOWS\system32\eventlog.dll

Some infections are difficult to remove completely because of their morphing characteristics which allows the malware to regenerate itself. Sometimes there is hidden piece of malware (i.e. rootkit) which has not been detected by your security tools that protects malicious files and registry keys so they cannot be permanently deleted. Disinfection will probably require the use of more powerful tools than we recommend in this forum. There are some new tools which will help confirm and remove the infection. However, before that can be done you will need you to create and post a DDS/HijackThis log for further investigation.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

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. 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.

I seem to be having some problems with the two tools from your last post. I followed the directions for DDS but when i double click the icon i don't get any black box that pops up. Instead it goes right into a notepad file and opens up something that looks like this:

MZP    @     !L!This program must be run under Win32
$7 PE L pH    PC  P @     p       d  P  UPX0    UPX1   @ .rsrc P  @ 3.03 UPX!

except alot longer. On the directions the DDS file type was listed as a screensaver file but on my computer it is an AutoCAD file. Is there anyway to change the file type and still get the program to function the same way?

I also went on to try the RootRepeal program. That program freezes and then restarts my computer right after i hit the Scan option.

If you cannot get DDS to work, please try this instead.

Please download RSIT by random/random and save it to your Desktop.
Note: You will need to run this tool while connected to the Internet so it can download HijackThis if it is not located on your system. If you get a warning from your firewall or other security programs regarding Rist attempting to contact the Internet, please allow the connection.
  • Close all applications and windows so that you have nothing open and are at your Desktop.
  • Double-click on RSIT.exe to start the program.
  • If using Windows Vista, be sure to Run As Administrator.
  • Click Continue after reading the disclaimer screen.
  • Leave the drop down box set to default: "List/folders created or modified in the last 1 month (30 days).
  • When the scan is complete, a text file named log.txt will automatically open in Notepad.
  • Save the log file to your desktop and copy/paste the contents into a new topic in the HijackThis Logs and Malware Removal forum, NOT here.
Important: Be sure to mention that you tried to follow the Prep Guide but were unable to get DDS to run properly. If RSIT did not work, then reply back here.

RSIT starts to run but then shuts down similarly to the other virus scans. I also tried renaming the .exe file to something random but that didn't work either unfortuantly. :thumbsup:

FINALLY! I found someone with the same issue as me! Here's my info so far. I'm right now running the rootkit scanner (sophos) as mentioned above. HJT won't run, it starts then quits. It appears that whatever I have creates a hidden file that is the exact name of the exe. I'll update as it goes on. Let me know if you find a solution.

Like it says ComboFix, HJT, Ad Aware all close shortly after starting to scan and so I can't get a log file or anything. After I run them once I can't run them again, I get an error about not having suffecient permissions. I have a Windows Ultimate Boot disk and I've used that to boot and run SuperAntiSpyware and it removed a bunch of stuff but still hasn't resolved this issue, also, I got Avira Anti-Virus to run fine and it removed about 16 viruses, also, on the boot disk I got Spybot S & D to run and it found some things and cleaned them as well but I'm still having the same problem. I can't scan (even in safe mode) the computer with ANY adware/spyware programs they all just close out randomly as does HJT and ComboFix. Any ideas?

XP Home, HP Pavilion Dv 1000

I have now run a temp file clean-up/removal tool, about 3 anti-virus scans (all are clean now) and have developed an interesting issue. If I open control panel it won't open, then when I reboot I find that explorer.exe has been infected so I have to boot with the diagnostic CD and delete explorer.exe and replace it with one off the cd to get it to work again.

Stumbled across this someone else working on what looks like the same issue I'm having. I've noticed that eventlog.dll seems to be the common file (that's how I found his thread), my sophos rootkit scan is still running but that file popped up. I'll keep you updated.
