Hello, Inquistive:
No legitimate extension/add-on will automatically install itself into Firefox, and it does not turn up on a search of the AMO site (though some legitimate devs choose not to host their extensions at AMO).
And a quick Google search turns up several hits about this being some form of spyware.
Since we don't work on malware detection or removal in this particular sub-section of the forums, it might be advisable to have one of our malware experts take a peek under the hood of your system & assist you with removing this pest, if need be.
PLEASE CHOOSE ONE OF THE FOLLOWING 3 OPTIONS:
OPTION 1: Free, one-on-one, expert assistance in the Malware Removal Forum.
OPTION 2: For paid users of MBAM PRO, free, one-on-one, expert assistance from MBAM support.
OPTION 3: Fee-based, one-on-one, expert assistance from Premium Support.
OPTION 1:- Please print out, read and carefully follow the instructions in the "I'm Infected - What Do I Do Now?" article.
- If the infection has so crippled the computer that you cannot complete some or all of the steps, then just do the best you can and start a new topic as described below.
- Then please start a new post in the Malware Removal Forum.
- When starting your new post, please note the following:
- Please do NOT post in a topic started by someone else, even if their problem sounds similar.
- Please COPY/PASTE the requested logs into your post, rather than attaching them.
- Under options, please be sure to select "track this topic" and "immediate email notification", so you'll know when a helper responds.
- Please be patient - it may be 48 hours or more before a helper can assist you, especially when the forum is very busy.
- Please do NOT "bump" your topic or reply back to it for at least 48 hours.
- Doing so may cause your topic to be overlooked, as it will appear that you are already being helped.
OPTION 2:
If you are a paid user of MBAM PRO and prefer expert assistance via email, please send an email to
support@malwarebytes.org, or contact the help desk
