For past few weeks, I've been getting notification saying that some file are infected by bloodhound.exploit.196. I tried so many things to get rid of it, but it keeps coming back (I disabled system restore, quarantined, deleted using avast application, scanned with Malwarebytes' Anti-Malware and hijackthis but it's keep coming back).
Currently files infected are Acr5D5C.tmp, DWHD881.tmp, DWH8069.tmp, trz4C0C.tmp, trzA1AB.tmp, and trz2E83.tmp.
I'm afraid my computer is going to get messed up. Is there anything I can do???

Once you get SDFix downloaded go offline, turn off your antivirus, and turn off any antispyware that you have, run SDFix from safe mode and restart the Antivirus before you get back on line to post the log.

Download SDFix.exe and save it to your Desktop.
Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with SDFix or remove some of its embedded files which may cause "unpredictable results".
Click on This Link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
Remember to re-enable the protection again afterwards before connecting to the Internet.

1.Double click SDFix.exe and choose Install to extract it to its own folder on the Desktop. Please then reboot your computer in Safe Mode by doing the following :
Restart your computer
After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;
Instead of Windows loading as normal, a menu with options should appear;
Select the first option, to run Windows in Safe Mode, then press "Enter".
Choose your usual account.
2. Open the c:\SDFix folder and double click RunThis.cmd to start the script.
Type Y to begin the script.
It will remove the Trojan Services then make some repairs to the registry and prompt you to press any key to Reboot.
Press any Key and it will restart the PC.
3. Your system will take longer that normal to restart as the fixtool will be running and removing files.
When the desktop loads the Fixtool will complete the removal and display Finished, then press any key to end the script and load your desktop icons.
4. Finally open the SDFix folder on your desktop and copy and paste the contents of the results file Report.txt

Please download Malwarebytes' Anti-Malware from one of these sites:



Rename the setup file, mbam-setup.exe, before you download it. To do that once the "enter name of file to save to" box appears as the download begins in the filename box rename mbam-setup.exe to tool.exe> click save.

1. Double Click tool.exe to install the application.
2. Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
3. If an update is found, it will download and install the latest version.
4. Once the program has loaded, select "Perform Quick Scan", then click Scan. The scan may take some time to finish,so please be patient.
5. When the scan is complete, click OK, then Show Results to view the results.
6. Make sure that everything found is checked, and click Remove Selected.
7. When disinfection is completed, a log will open in Notepad and you may be prompted to Restart. If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process,if asked to restart the computer,please do so immediately.
8. The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
9. Copy&Paste the entire report in your next reply.

If Malwarebytes installed but will not run navigate to this folder:

C:\Programs Files\Malwarebytes' AntiMalware

Rename all the .exe files in the MAlwarebytes' Anti-Malware folder and try to run it again.

Please download and install the latest version of HijackThis v2.0.2:

Download the "HijackThis" Installer from this link:
Hijack This

Rename the setup file, HJTInstall.exe, before you download it. To do that once the "enter name of file to save to" box appears as the download begins in the filename box rename HJTInstall.exe to tools.exe> click save.
1. Save " tools.exe" to your desktop.
2. Double click on tools.exe to run the program.
3. By default it will install to C:\Program Files\Trend Micro\HijackThis.
4. Accept the license agreement by clicking the "I Accept" button.
5.Click on the "Do a system scan and save a log file" button. It will scan and then ask you to save the log.
6. Click "Save log" to save the log file and then the log will open in Notepad.
7. Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log.
8. Paste the log in your next reply.
9. Do NOT have HijackThis fix anything yet! Most of what it finds will be harmless or even required.

So I installed SDFix,exe, but when I open the c:\SDFix folder from safe mode, the script flashes and disappears.
Also, I accidentally double clicked SDFix program in a regular window xp mode. Is that okay?

Navigate to C:\SDFix and see if it exist. If it does not right click the SDFix icon on your desktop and click run.

Reboot into safe mode> navigate to the C:\SDFix folder> right click it> click open> double click the "RunThis" batch file and SDFix should run.

Make sure you av is off.
