Firefox performed an update (I think to version 18) and after that, it crashes when I try to open it. It crashes when I try to start in safe mode as well.

I have performed a complete uninstall and reinstall several times. I've checked all the solutions listed in the database and none of them seem to help. I've downloaded the two recommended malware removal programs, performed a complete scan, but they come up with nothing. I've tried to get the details from the error report, but the crasher reporter won't display any. The only thing I get in D:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Crash Reports\ is a file called LastCrash with the number 1357955879 in the file.

I am running Windows 7, everything has been updated; OS, virus definitions, drivers, etc.

Re: Firefox performed an update (I think to version 18) and after that, it crashes when I try to open it. It crashes when I try to start in safe mode as well.

I updated MS Security Essentials and ran an extensive scan. It found a few items, but I don't think the pabbbtyx.dll was listed. Does anyone know where the MS Security Log files are stored? I can verify if it was. The reason is, I am not sure if that is the fix or not. I went in to msconfig and noticed that the DT Soft file, pabbbtyx.dll was set to load on startup. I was able to disable it from startup and now Firefox is working correctly.

So really I don't know if my system is completely clean or if disabling that on startup worked. I guess I could re-enable it to see, but I don't feel like dealing with it now. I have too many issues with this lately and just don't feel like it. Later, I will re-enable it to see if it made a difference and post a reply.

Looks like a Bug report exists for that type of crash.

It looks like both the Kaspersky Security Scanner and MS Safety Scanner programs will find that Malware.

Do a malware check with some malware scanning programs on the Windows computer.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.

I've run all the malware checks mentioned. Kapsersky and MS Safety Scanner didn't find anything. Updated Windows Defender and Super Antispyware and ran a scan, but with no luck. I ran the TDSSKiller and it found a locked file, sptd(?), but that didn't fix the problem either.

I rebooted and tried Firefox again, but it still crashed. Crash ID: bp-beaa46c9-a8dc-4f94-8f36-8c75a2130112

I am in the process of doing a full scan with Spybot Search and Destroy.

Update: I completed a full scan with Spybot and it found some malware, but it was mostly tracking cookies. I cleaned everything and tried again. Still no luck with Firefox. I performed a complete deinstall, rebooted, redownloaded the latest firefox setup, then reinstalled. No luck.

Are you able to locate this file that shows in the modules list of the crash report: pabbbtyx.dll

If you can't find the file then boot the computer in Windows Safe mode with network support (press F8 on the boot screen) to see if that helps.

other users have reported that microsoft safety scanner catches & removes this malware - so try to run a scan with it too: http://www.microsoft.com/security/scanner/default.aspx
