How do I stop a Browser Hijacking by FileCure?

[Servant]

Some time ago, when trying to look at .dat files, I clicked on "Use the web service to find the appropriate program". Microsoft suggested that I download "Free File Viewer". The website seemed a little shady, especially since it wanted mt o install a lot of pointless stuff too, but I installed it anyway (stupidly).

"Free File Viewer" does work in allowing you to view the .dat file, but ".dat" can be opened up in many programs; what matters if you could actually understand it, and "Free File Viewer" failed in that regard. So I uninstalled it, woo-hoo.

Except now, when I click on "Use the web service to find the appropriate program"...and instead of directing me to the Microsoft website, it directs me to www.filecure.com. I suspect this is the exact same company that made "Free File Viewer", and so I want to remove this browser-hijacking so that I return back to the Microsoft website and get their support (even though their "support" led me to this problem in the first place).

The question is how? I have installed Malbytes and doing a Quick Search, but I can't find any Malware program. What should I do now?

Hi, and Welcome to Malwarebytes!

Please read the following so that you can begin the cleaning process:

As we don't deal with malware removal in the General Malwarebytes' Anti-Malware Forum, you need to start a topic in the Malware Removal forum so a qualified helper can help you fix any malware related problems/infections you may have.

• Please read and follow the directions here, skipping any steps you are unable to complete. Then post a NEW topic here.
  
• After posting your new post, make sure under options, you select Track this topic and choose Immediate Email Notification, so that you're alerted when someone has replied to your post.
  
• One of the expert helpers there will give you one-on-one assistance when one becomes available.
  
• Please refrain from making any further changes to your computer (Install/Uninstall programs, use special fix tools, delete files, edit the registry, etc...) unless advised by a malware removal helper. Doing so can result in system changes which may hinder the attempts by a helper to clean your machine.
  

NOTE: Please DO NOT post back to (bump) your topic within the first 48 hours.

Replying to your own posts changes the post count and helpers are looking for topics with zero replies. If you reply to your own post helpers may think that you're already being helped and thus overlook your post.

• • If there is no reply from any experts after 48 hours, you can reply to the topic, asking for help again.
    Or
    
  • You may send a Private Message to a Moderator asking for assistance.
    

Alternatively, as a paying customer, you can contact the help desk at support@malwarebytes.org or here.

Please be patient, someone will assist you as soon as it is possible.

PS: Please use the "ADDREPLY" button instead of other ones when you start replying.

Just to add.....

this is coming from a good source.....

They are informing me it's actually the program called "Free File Viewer" doing this, by hijacking a setting in the registry.

Not sure what version of windows you are using, but here are the setting from my XP computer. If you feel comfortable with checking your registry look for this key and check the settings:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Associations]

The hijack can be corrected by changing it to the right values: (These values are from an XP 32bit)

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Associations]
"XMLLookup"="http://shell.windows.com/fileassoc/fileassoc.asp?LangID=%04x&Ext=%s"
"Application"="http://shell.windows.com/fileassoc/%04x/xml/redir.asp?Ext=%s"
"intl"="http://shell.windows.com/fileassoc/fileassoc.asp?LangID=%04x&Ext=%s"

These were added Yesterday to Mbam. They will be replaced with the correct default values.
