Infected Trojan.agent svchost.exe

[lgambrell]

I had several viruses. Purchased malware bytes and was able to remove all except the Trojan.Agent in svchost.exe. I have tried numerous options, deleted restore points, booted in safe mode, etc... to no avail. I am running window7 professional with AVG anti-virus. Please help?

Welcome to the forum.

Please remove any usb or external drives from the computer before you run this scan!

Please download and run RogueKiller to your desktop.

For Windows XP, double-click to start.

For Vista or Windows 7, do a right-click on the program, select Run as Administrator to start, & when prompted Allow to run.

Click Scan to scan the system.

When the scan completes > Close out the program > Don't Fix anything!

Don't run any other options, they're not all bad!!!!!!!

Post back the report which should be located on your desktop.

Please download the latest version of TDSSKiller from here and save it to your Desktop.

• Doubleclick on TDSSKiller.exe to run the application, then click on Change parameters.
  
  
• Put a checkmark beside loaded modules.
  
  
• A reboot will be needed to apply the changes. Do it.
  
• TDSSKiller will launch automatically after the reboot. Also your computer may seem very slow and unusable. This is normal. Give it enough time to load your background programs.
  
• Then click on Change parameters in TDSSKiller.
  
• Check all boxes then click OK.
  
  
• Click the Start Scan button.
  
  
• The scan should take no longer than 2 minutes.
  
• If a suspicious object is detected, the default action will be Skip, click on Continue.
  
  
• If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  
  Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.
  
• A report will be created in your root directory, (usually C:\ folder) in the form of "TDSSKiller.[Version]_[Date]_[Time]_log.txt". Please copy and paste the contents of that file here.

When I ran the first time, It actually unchecked the additional options . It found a malicious threat which i asked to cure, rebooted and scanned again, so I am pasting both logs. Malware is still popping up with malicious virus with option to ignore or quarantine. I tried to paste logs, but said post to long, so am attaching files

TDSSKiller.2.8.7.0_20.08.2012_13.51.00_log.txt

[MrCharlie]

Run TDSSKiller again and choose Delete for this one only: (no need to post the log)

Please download and run ComboFix.

Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Information on disabling your malware programs can be found Here.

Make sure you run ComboFix from your desktop.

Give it at least 30-45 minutes to finish if needed.

Please include the C:\ComboFix.txt in your next reply for further review.

---------->NOTE<----------

If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.

Should I delete the quarantined items?

[MrCharlie]

Great

A little clean up to do....

Please Uninstall ComboFix: (if you used it)

Press the Windows logo key + R to bring up the "run box"

Copy and paste next command in the field:

ComboFix /uninstall

Make sure there's a space between Combofix and /

Then hit enter.

This will uninstall Combofix, delete its related folders and files, hide file extensions, hide the system/hidden files and clears System Restore cache and create new Restore point

(If that doesn't work.....you can simply rename ComboFix.exe to Uninstall.exe and double click it to complete the uninstall)

---------------------------------

Please download OTL from one of the links below: (you may already have OTL on the system)

http://oldtimer.geekstogo.com/OTL.exe

http://oldtimer.geekstogo.com/OTL.com

http://www.itxassociates.com/OT-Tools/OTL.exe

Save it to your desktop.

Run OTL and hit the CleanUp button. (This will cleanup the tools and logs used including itself)

Any other programs or logs you can manually delete.

IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST, etc....

-------------------------------

Any questions...please post back.
