Elise025 and Fabar were able to help me when I posted a problem on 12/31/09 (I had a rootkit virus). Thank you so much you were both a big help.

I am not sure if my CURRENT problem is related. But I need HELP again.

When I try to run Malwarebytes Antivirus I get the BLUE SCREEN. The blue screen mentions iastor.sys (which is part of where the problem was the last time). Malwarebytes will not completly run the blue screen comes on each time. I have uninstalled and reinstalled it and I get the blue screen each time.

I ran GMER and here is the log:

GMER 1.0.15.15281 - http://www.gmer.net

Not all hidden components detected by ARKs are malicious. It is normal for a Firewall, some Anti-virus and Anti-malware software (ProcessGuard, Prevx1, AVG AS), sandboxes, virtual machines and Host based Intrusion Prevention Systems (HIPS) to hook into the OS kernal/SSDT in order to protect your system. SSDT (System Service Descriptor Table) is a table that stores addresses of functions that are used by Windows. Whenever a function is called, Windows looks in this table to find the address for it. Both Legitimate programs and rootkits can hook into and alter this table. You should not be alarmed if you see any hidden entries created by legitimate programs after performing a scan.

Some files are locked by the operating system or running programs during use for protection, so scanners cannot access them. When the scanner finds such a file, it makes a note and then just skips to the next one. API Kernel hooks are not always bad since some system monitoring software and security tools use them as well. If no hooks are active on a system it means that all system services are handled by ntoskrnl.exe which is a base component of Windows operating systems and the process used in the boot-up cycle of a computer.

mohfilt.sys is a driver for Intel Corporation
iastor.sys is a driver for Intel's Matrix Storage

Are you getting the BSOD only when running MBAM?

I would Uninstall MB and run regedit and delete all entires for MB then reinstall MB. Like the above poster asked," does the BSOD only happen when running MB?"

That's what I already asked.

I only get the blue screen when I run Malwarebytes Antivirus. I ran the superantispyware fine (it only showed a few tracking cookies).

The error on the blue screen mentions Iastor.sys.

Malwarebytes Antivirus does not complete running. The bluescreen comes up and I have to turn the computer off and on.

I have always been able to run it. Not sure why I cant now.

I did uninstall it and reinstalled it and still the same problem.

I am not sure about "run regedit and delete all entires for MB" that whiteac2k4 mentions. Do I need to do this.. and if so how would I do it.

Quietman7, What do I need to do. Please advice.

Thanks,

Since the problem only occurs when using MBAM, I recommend you report this issue in the Malwarebytes Anti-Malware Support Forum or E-mail the Malwarebytes Support Help Desk so the development team can investigate the cause.
