As you appear to have access to another machine, can you download and create a Kaspersky Rescue Disk to boot up with. -
https://support.kaspersky.com/viruses/krd18While AdwCleaner is now part of MBAM and MBAM has found and removed PuPs and PuMs, running a scan with that may help to get your system back up.
https://www.malwarebytes.com/adwcleaner/Can you boot into Safe Mode with Networking via tapping F8 as you switch on, as I would advise running the scan in that mode.
As you have Win 7 Ultimate, do you also have an Ultimate install disk that you can boot up with ?
If you have, boot up with that and navigate to the Install screen to select Repair your computer.
Select Command Prompt and enter these cmds -
bcdedit |find "osdevice"
For clarity that is a Pipe symbol before find and is the uppercase of \
Using your partition letter instead of the x I have exampled, enter -
dism /image:x: /cleanup-image /revertpendingactions
Enter exit to close the cmd window and reboot.
If that doesn't improve things then reboot with your install disk to select the Command Prompt again and again using your partition letter instead of the x I have exampled, enter -
sfc /scannow /offbootdir=X:\ /offwindir=X:\Windows
to see what that reports.
As a final solution, I don't know if you will be able to do this but with Windows booted up, go Start - click on Computer - insert the install disk and double click on its drive.
This will start the process of a repair install which doesn't affect personal files or installed programs but you will need a valid retail key.
If you are using an OEM machine where Ultimate came pre-installed, then you can use the key on the COA Sticker.
