Thanks for that link!
I think I understood it; that once Malwarebytes is updated to 3917 and scan shows no infection then is no problem.
I am wondering two things more.
One or two threads in Bleeping Computer had root kits and I think other problems after the infection of security.hijack, though of course may have been unrelated so just a bit concerned on that.
The other thing is, if that file that is now quarantined is okay, do I need to restore it?
ETA: I see from a pinned thread in this forum that a staff member from Bleeping would be the one to reply to this post. Thank you Trollics for your help.
