A good friend told me yesterday that he's been trying to get BT out to fix his router. Unfortunately he was phoned on the weekend by some scammers who claimed they were from BT and he allowed them remote access to his laptop and they downloaded some software. At the point that they asked him to log on to his internet banking he hung up and uninstalled the software.
I urged him to update and run Malwarebytes and SuperAntiSpyware as well as his Avast antivirus.
He's told me that he ran the MalwareBytes scan and it didn't find anything but it then asked him to update it. He did, then it asked him to reboot. He did and upon restart it is asked him for the admin password, he put it in but now can't get it to safe mode or to progress in to windows at all.
C: is windows as normal
D: recovery windows sets up a small recovery drive when you install, I'm guessing that win 10 was an upgrade from a windows 8 or 8.1 originally on the machine hence the two recovery drives, these are normally hidden.
E: is the DVD drive
Vol 3 is likely to be the system reserve partition where all the boot files are located for win 8 or 10
Vol 4 win RE is where windows puts its tools so you can boot to the recover environment and do things like start up repair, system restore or reset the computer.
Surprised both showing as D: with one hidden but looking again 14GB is too big for the normal win recovery so must be a recovery partition set up for the laptop containing a disk image.
Untill he can get back in windows its hard to tell
I would be tempted to connect laptop to another machine extracted any data required (photos docs emails etc.) then use diskpart to completley wipe the drive and do a freh install from the boot media. That way he can be certain there is no lingering malware, trojans, keyloggers, etc.
To reinstall windows in this case I would say the best way is to use the windows 10 media on a cd / usb. That way you know you are getting a completely clean install. Click here for the download link.
I would also say that it would be a good idea to completely clean the hard drive first if there is definitely no important data. that way you won't get any lingering partitions. You can access the command prompt from the installation media I linked earlier, then follow this guide to clean the disk. Once that is complete restart the pc and you can reinstall a completely fresh copy of windows from the usb. This will remove all data completely so make sure they are happy with this being done before you do it!
To get to command prompt from the installation media, click "repair this pc" when the install screen comes up, then "troubleshoot", it may be under "advanced options". You can run diskpart from there.
