No malware detected, but can't install any antivirus

Welcome to Major Geeks!

You need to attach the other two logs requested in the below procedure:

READ & RUN ME FIRST. Malware Removal Guide

The logs you are missing are from Hitman Pro and MGtools. We need these to continue.

Based on your ComboFix like, you still have TrendMicro installed ( at least it was not fully uninstalled ) and you should not be trying to install another antivirus program.

 

Please attach the logs from TDSSKiller and Malwarebytes too.

 

Okay but now the MGtools logs are all out of date and still show TrendMicro since you did not run MGtools after uninstalling TrendMicro. Hence I still cannot tell if everything was properly uninstalled. I do see a driver for Panda in your ComboFix log too.

Let's make an assumption that TrendMicro did not uninstall properly and run a fix for this along with another tool.

Let's begin with some uninstalls. Uninstall the below.
Coupon Printer for Windows >>> Not safe. See http://www.dslreports.com/forum/r20236965-Is-installing-a-Coupon-Printer-safe
Java 2 Runtime Environment, SE v1.4.2_02
Java(TM) 6 Update 33
Panda ActiveScan 2.0


Be patient while doing the below. The fixes can take quite awhile to run. Especially the permissions repairs. It may be best to kick it off and goto bed or do something else. It is better not to run anything while the repairs are going on.


Download Windows Repair by Tweaking.com and unzip the contents into a newly created folder on your desktop.

• Now run Repair_Windows.exe by double clicking on it ( if you are running Vista or Win 7, use right click and select Run As Administrator)
• Now select the Start Repairs tab.
• The click the Start button.
• Create a System Restore point if prompted.
• On the next screen, click the Unselect All button to first deselect all repairs.
• Now select the following repair options:
  • Reset Registry Permissions
  • Reset File Permissions
  • Register System Files
  • Repair WMI
  • Remove Policies Set By Infections
  • Repair Winsock & DNS Cache
  • Repair Proxy Settings
  • Repair Windows Updates
  • Set Windows Services To Default Startup
• Now on the lower right side check the box to Restart/Shutdown System When Finished
• Then make sure the Restart System radio button is enabled.
• Shutdown any other programs that you are running now before continuing.
• Now click the Start button.
• Be patient while the tool repairs the selected items.
• It should reboot automatically when finished.

Now we need to use ComboFix

• Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
  • If it is not on your Desktop, the below will not work.
• Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
• If ComboFix tells you it has expired or need to be updated to a new version, make sure you allow it to update.
• Open Notepad and copy/paste the text in the below quote box into it:

• Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
• At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
• You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
• Now use your mouse to drag CFscript.txt on top of ComboFix.exe
• Follow the prompts.
• When it finishes, a log will be produced named c:\combofix.txt
• I will ask for this log below

Note:

Do not mouseclick combofix's window while it is running. That may cause it to stall.

If after running Combofix you discover none of your programs will open up because you recieve the following error: Illegal operation attempted on a registry key that has been marked for deletion then you will need to reboot your computer which will normally fix this problem.

After reboot, now install the current version of Sun Java from: Sun Java Runtime Environment

Now download and save the below to your DESKTOP!!!! Then right click on it and select Run As Administrator. If you run into any problems, tell me EXACTLY what happens and exactly what messages you receive.

Avira Free Antivirus


Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Win7, don't double click, use right click and select Run As Administrator).


Then attach the below logs:

• C:\ComboFix.txt
• C:\MGlogs.zip

 

Okay! Once you finish those instructions and attach the new logs, we can continue.

 

Yes just continue on.

 

Okay skip Avira and continue.

 

You're welcome.

It does not appear that this is related to malware as your logs are clean. However let's run a couple more scans to be sure.


Please do the below so that we can boot to System Recovery Options to run a scan.

For 32-bit (x86) systems download Farbar Recovery Scan Tool and save it to a flash drive.
For 64-bit (x64) systems download Farbar Recovery Scan Tool x64 and save it to a flash drive.

Plug the flashdrive into the infected PC.

Enter System Recovery Options from the Advanced Boot Options:

• Restart the computer.

• Use the arrow keys to select the Repair your computer menu item.
• Select US as the keyboard language settings, and then click Next.
• Select the operating system you want to repair, and then click Next.

On the System Recovery Options menu you will get the following options:

• In the command window type e:\frst.exe (for x64 bit version type e:\frst64) and press Enter
  Note: Replace letter e with the drive letter of your flash drive.
• The tool will start to run.
• When the tool opens click Yes to disclaimer.
• Press Scan button.
• It will make a log (FRST.txt) on the flash drive. Please attach this file to your next reply. (See: How to attach)

Now please download OTL by OldTimer.
