Firefox files in Malwarebytes scan

[johnsproul]

Just ran a Malwarebytes scan and it detected these two files. Before I quarantine these two I thought I'd ask your opinion. Both are Firefox files, and the last I quarantined something like them I lost all my Firefox customizations. Do these two look suspicious to you?

 

Files: 2

PUP.Optional.Trovi.A, C:\Users\John C Sproul\AppData\Roaming\Mozilla\Firefox\Profiles\9724fpi9.default\prefs.js, Good: (), Bad: (user_pref("browser.startup.homepage", "http://www.trovi.com/?gd=&ctid=CT3322288&octid=EB_ORIGINAL_CTID&ISID=MDB29B4D8-31C9-4A7F-B708-29D463BD9CF6&SearchSource=55&CUI=&UM=8&UP=SPF37A687E-26F8-4C4B-B237-8C94774EA859&SSPV="), ,[7d8822fa583280b679355c967f869c64]

 

PUP.Optional.Trovi.A, C:\Users\John C Sproul\AppData\Roaming\Mozilla\Firefox\Profiles\9724fpi9.default\prefs.js, Good: (), Bad: (user_pref("browser.newtab.url", "http://www.trovi.com/?gd=&ctid=CT3322288&octid=EB_ORIGINAL_CTID&ISID=MDB29B4D8-31C9-4A7F-B708-29D463BD9CF6&SearchSource=69&CUI=&SSPV=&Lay=1&UM=8&UP=SPF37A687E-26F8-4C4B-B237-8C94774EA859"), ,[45c0120aaae0c96dd3dceb0795701ce4]

 

If these are both OK, if I check "Ignore" on the results page, will that prevent them from showing up on future scans?

I don't recommend you ignoring those. They appear to be browser hijacks. One for new tab and the other for home page. I recommend changing the home page to about:blank and new tab page to about:newtab.

The safest way is to reset firefox profile to default in order to remove these hijacks. Make sure you backup bookmarks, extensions settings and digital certificates if apply.

Also, make sure you got rid of the browser hijacker. You may want to wait for a more professional member to reply.
