Hey guys. So yesterday I noticed firefox wasn't opening. Everytime I'd click it I'd get the windows message "Mozilla Firefox has stopped working."

At the time, I didn't think much of it. However, shortly after, I was immediately bombarded by pop-ups claiming I had virus infections and the like. Upon checking my processes in the Task Manager I saw settdebugx.exe. I tried opening IE because Firefox wouldn't open, and I got another windows alert saying "Internet Explorer has stopped working."

I immediately googled isettdebug.exe on another PC and all solutions pointed towards MalwareByte's Anti-Malware program. I downloaded it on the second computer and transferred it to the infected one. I tried running it, and I got "Mbam-setup.exe has stopped working."

On the Malware site, it says that certain trojans prevent the installer from running, and that all I need to do is rename the installer and run it. I did it, and it worked. It found the trojans and removed them.

However, on startup I get messages saying IE and Windows Defender have stopped working. Firefox still wont open. The message saying IE has stopped working actually pops up every 2 or so minutes.

I rescanned with Malware Bytes and it has found nothing. My system restore doesn't work (a big problem, I'm working on it), and I'm out of ideas.

I'm running 32-bit Vista on a HP Compaq 8510p laptop. I have a HijackThis log but I'm not sure if I should post it yet or not because of the rules.

Thanks for any help guys.

EDIT: After some more work and a couple more scans I found a Vundo infection and a rootkit. I removed them both using MalwareBytes, but IE, Firefox and Windows Defender will still not open. I downloaded rkill, and once I run it IE works properly, but Windows Defender still wont stat. This means that something is still infected right? Additional scans do not find anything.

Welcome to BC

If you wish to post a HJT log, please follow these instructions:

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

You will also be instructed to create a Root Repeal Log

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

The HJT team is very busy and it will take awhile to get to your post
Please be patient and good luck
