Hello everyone! My computer keeps freezing up. I have run Ad-aware and it detects win32TrojanTDSS. Afterit detects it, it says it needs to reboot in order to get rid of it but it keeps showing on following scans. I have tried running AVG antivirus but it won't finish scanning. I have tried to run Spybot but apparently the malware is blocking it and doesn't allow it to run. I would appreciate it if someone gives it a bit of his/her time to help me out here. Thank you.

Hello and welcome to Bleeping Computer.

Please subscribe to your topic so that you will be notified as soon as I post a reply, instead of you having to check the topic all of the time. This will allow you to get an email notification when I reply.

To subscribe, go to your topic, and at the top right hand corner by your first post, click the Options button and then click Track this topic. The bullet the immediate notification bubble. Then press submit.



I am sorry but I have bad news:

One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identity Theft, Internet Fraud, and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.

Unfortunately I do not have a copy of Windows XP so it is not possible for me to reformat. Also I do not do any kind of online banking so that is not an issue. I would appreciate it if you helped me with cleaning this machine for now. Thank you.

Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click zztoy.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
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.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

Ok, next, let's run RootRepeal, it looks like you have a rootkit.

Please install RootRepeal

Go HERE, and download RootRepeal.zip to your Desktop.
Tutorial with images ,if needed >> L@@K
Unzip that to your Desktop and then click RootRepeal.exe to open the scanner.

*Open the folder and double-click on RootRepeal.exe to launch it. If using Vista, right-click and Run as Administrator...
* Click on the Files tab, then click the Scan button.
* In the Select Drives, dialog Please select drives to scan: select all drives showing, then click OK.
* When the scan has completed, a list of files will be generated in the RootRepeal window.
* Click on the Save Report button and save it as rootrepeal.txt to your desktop or the same location where you ran the tool from.
* Open rootrepeal.txt in Notepad and copy/paste its contents in your next reply.
* Exit RootRepeal and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

Please note: If Rootrepeal fails to run, try this step: Click Settings - Options. Set the Disk Access slider to High


Note 2: If RootRepeal cannot complete a scan and results in a crash report, try repeating the scan in "Safe Mode".

I have tried running RootRepeal but when I run it, it shows repetitive error messages saying: "Could not read the boot sector. Try adjusting the Disk Access Level in the Options dialog". Then a window pops up saying "Could not find module file on disk!". Then the details show "Warning - could not read Windows kernel using raw-disk reading!" and three lines saying "Could not find module file on disk!". I changed the disk access level to high and then pressed scan and the initial error ("Could not read the boot sector. Try adjusting the Disk Access Level in the Options dialog") pops up again. Above the scan button it says "Initializing, please wait...". Am I being impatient or it is not running?

Hey guys I format my computer so the problem is solved. The trojan hijacked my internet browsers and was very frustrating. Anyway this topic can be closed now.
Thanks everyone for everything.

With the newest variants of this rootkit/backdoor trojan, a format and reinstall is the quickest and safest approach.
