how to remove Trojan Horse TDSS.BZ

Post by D3cimating Taco on Tue 06 Aug 2013, 11:22 am

First topic message reminder :

For a while now there have been all sorts of pop-ups and random programs on my computer. I decided to download AVG free and go into control panel and uninstall everything that looked potentially harmful. AVG free found and deleted a lot of threats it found but for some reason it found "Trojan horse TDSS.BZ" and it says that it can't remove it because "Access is denied." How do I get rid of this Trojan horse?
Edit: The scan is still running and it's finding more adware that it can't remove. I believe the source that it found was a program called "Resident shield" it's finding many things that it can't remove.

Hey, sorry that I'm on a different account, I'm the friend of d3cimating taco who's been posting for him on his account if that makes sense. Anyway, after 10-15 minutes of being on, windows stops responding.

What does it do? Does it give any warning messages? Does it shut down your computer?

The computer used to say the program is unresponsive (microsoft windows) would u like to terminate process? And then it didnt let me click either option. But now it just becomes unresponsive without a warning and your mouse is the little circle that symbols it is loading, then eventually it just stops and is a faded part of my desktop background, so then i just have to press the power button. It's gotten to the point where i just want to restpre windows at a shop now.

That could be your best option. It could be any number of things causing this problem; bad hard drive, bad RAM, overheating etc.Save your important data to DVD's or an external drive. Since you have Windows 7 you can try doing a repair from the Recovery Console. If that doesn't help, you can restore it back to the factory defaults.
Or you could try this:


That could be a problem with bad RAM. Please run this check just to eliminate that possibility.
Test your RAM here.
******************************************************
Run hard drive diagnostics: tacktech.com
Make sure, you select tool, which is appropriate for the brand of your hard drive.
Depending on the program, it'll create bootable floppy, or bootable CD.
If downloaded file is of .iso type, use ImgBurn: imgburn to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.
For Toshiba hard drives, see here:

Note : If you do not know how to set your computer to boot from CD follow the steps here
********************************************
To check if it's overheating you can download and install a program like SpeedFan.

Download Windows Repair (all in one) from this site
Install the program then run it.

Go to Step 2 and allow it to run CheckDisk by clicking on Do It button:



Once that is done then go to Step 3 and allow it to run System File Check by clicking on Do It button:



Go to Step 4 and under "System Restore" click on Create button:



Go to Start Repairs tab and click Start button.



Please ensure that ONLY items seen in the image below are ticked as indicated (they're all checked by default):



Click on box next to the Restart System when Finished. Then click on Start.

I reinstalled windows 7 and it works perfectly now. Just out of curiosity, do you know what the problem might've been?

It looks like it may have been a corrupted file in the OS.
