Windows 10: MalwareBytes Detects Safe File All the Time.. What to do?

I got firefox installed. When i run Malwarebytes it identifies and quarantines 'pref.js' in the firefox directory. But its supposed to be a needed and safe file which is part of firefox. After its quarantined and I run Malwarebytes again, it detects it again! Why is this happening and what do i do about this?

Malwarebytes = False Positive??

Recently downloaded Malwarebytes and decided to do a quick scan after noticing random slow downs on my machine.

Now i regularly run a full scan with Windows Defender and KIS using the full rootkit scan option.

when I ran Malwarebytes. it came up with this





I googled this after it was detected and theres not really that much information on it at all. but whatever little information there is, conflicts with one another.

There are some sites that say that it isnt a threat. then there are those that say it is a 'medium' threat and describes how to remove it.

Ive tried using Malwarebytes to remove it more then 5 times. I even went into safe mode to scan and see if i can removed them both with Malwarebytes and both manually following the steps on a website. however. even though Malwarebytes has detected the threat in that particular folder. when i do a file search or look for it manually with folder options set to show all hidden files. I cant seem to find it at all. and the only UL.dll file is located in a Roxio Shared folder.

Windows defender didnt pick anything up. Kaspersky 2012 on a full custom scan with the rootkit option selected didnt pick anything up.

and i have OCD so im starting to panic as i dont want to completely reinstall windows as this install is pretty fresh.

I have no idea how something like this would get past kaspersky and regular scans. Im always careful of the sites i visit otherwise kaspersky would block me from entering the site.

WHAT DO I DO?

It appears that a few are having problems with malwarebyte and AVG detecting it as a trogan.

Does Malwarebytes work?

A lot of people recommended Malwarebytes for Anti-spy/malware, but I have a concern with this free program. Ok so Windows detected some trojans/ adware in both my C: and D: drive, so I then ran Malwarebytes and the program prompt this: "

" *Wtf :wtf:

So I ran another program that I used in the past called SUPER-antispyware and it detected 13 trojan/ adware files. *Nutkick :nutkick:

My question is: Windows and Super-antispyware found these threats but not Malwarebytes? I have good things about this program, but it has been ineffective for me.:shadedshu Is this program not designed to find certain files?

Edit: Yes, I have ran all updates before I ran the sanning.
