Lenovo Y480,
Win 8.1.
Last month a Malware Bytes update started cannibalizing my system, quarantining over 600 driver files, .dlls and assorted stuff.
(Earlier part of that story here.
I tried to undo everything, and in the process uninstalled MBAM, thereby deleting the quarantined files. My system is full of holes, and won't do odd things, like recognise external USB hard drives or thumb drives. There are no system restore points prior to the problem.
This is a problem for me, because my laptop came without a system restore disc. I took the precaution of making a system restore image on a USB stick - but now the computer won't recognize the stick. It blings and registers something's being plugged in, but the drive won't show in finder.
MBAM solved the problem with an update, but despite their assertions that they want to help restore my system, they haven't done anything. The thread on this was closed on their support site, but no further support was forthcoming after they closed it. (See Here).
Any help getting my device to recognize my external USB stick would be appreciated. I'm in conversation with Microsoft to see if they can send me some kind of recovery media. Will update as that conversation develops.
