Hello and welcome to Safer Networking.

My name is km2357 and I will be helping you to remove any infection(s) that you may have.

I will be giving you a series of instructions that need to be followed in the order in which I give them to you.

If for any reason you do not understand an instruction or are just unsure then please do not guess, simply post back with your questions/concerns and we will go through it again.

Please do not start another thread or topic, I will assist you at this thread until we solve your problems.

Lastly the fix may take several attempts and my replies may take some time but I will stick with it if you do the same.


Step # 1: Disable Teatimer

Spybot S&D's tea timer normally provides real-time protection from spyware, however it may interfere with what we need to do. We will disable it until the machine is clean when it can be re-enabled.

This is a two step process.
First step: Right-click the Spybot Icon in the System Tray (looks like a blue/white calendar with a padlock symbol)
If you have the version 1.5 or 1.6, Click once on Resident Protection, then Right click the Spybot icon again and make sure Resident Protection is now Unchecked. The Spybot icon in the System tray should now be now colorless.
If you have Version 1.4, Click on Exit Spybot S&D Resident

Second step, For Either Version : Open Spybot S&D
Click Mode, choose Advanced Mode
Go To the bottom of the Vertical Panel on the Left, Click Tools
then, also in left panel, click Resident shows a red/white shield.
If your firewall raises a question, say OK
In the Resident protection status frame, Uncheck the box labeled Resident "Tea-Timer"(Protection of over-all system settings) active
OK any prompts.
Use File, Exit to terminate Spybot
Reboot your machine for the changes to take effect.


Step # 2 Download and run DDS

Download DDS and save it to your desktop from here (http://download.bleepingcomputer.com/sUBs/dds.scr) or here (http://www.forospyware.com/sUBs/dds).
Disable any script blocker, and then double click dds.scr to run the tool.
When done, DDS will open two (2) logs:
DDS.txt
Attach.txt

Save both reports to your desktop. Post them back to your topic.



Step # 3: Download and Run Gmer

Please download gmer.zip (http://www.gmer.net/gmer.zip) from Gmer and save it to your desktop.

***Please close any open programs ***

Double-click gmer.exe. The program will begin to run.

**Caution**
These types of scans can produce false positives. Do NOT take any action on any "<--- ROOTKIT" entries unless advised by a trained Security Analyst

If possible rootkit activity is found, you will be asked if you would like to perform a full scan. Click No.

If you do not receive notice about possible rootkit activity remain on the Rootkit/Malware tab & make sure that the 'Sections' button is ticked and the 'Show All' button is unticked. Click the Scan button and let the program do its work. GMER will produce a log.

Once the scan is complete, you may receive another notice about rootkit activity.
Click OK.

GMER will produce a log. Click on the Save button, and save the log as gmer.txt somewhere you can easily find it, such as your desktop.

DO NOT touch the PC at ALL for Whatever reason/s until it has 100% completed its scan, or attempted scan in case of some error etc !

Please post the results from the GMER scan in your reply.


In your next post/reply, I need to see the following:

1. The two DDS Logs (DDS and Attach.txt)
2. The GMER Log

Use multiple posts if you can't fit everything into one post.

D. Patel? Do you still need help?

At that point, if you still require help, please start a new topic and include a new HijackThis log with a link to your previous thread. Please do not add any logs that might have been requested in the closed topic, you would be starting fresh.

Applies only to the original poster, anyone else with similar problems please start a new topic.
