Hello! I need alot of help with cleaning up this hard drive, Its a friend that said he needed some help with cleaning up his computer so i brought it over to my house and to my suprise it barely even starts up. (at first it did not) so i mounted his hard drive into my PC which is how i have it right now. when i first started it up windows it told me that it needed to check the hard drive and it did so after that i put it back into his computer and it actually started up... but it had many problems which i will list below.
Regedit is disabled by admin
Task manager is disabled by admin (I found a prgram to re enable but it only works for a limited amount of time)
The desktop background is locked and cannot be changed (the background is a fake warning that he needs to download an antivirus and that his computer is infected)
the taskbar has disappeared (i tried unlocking taskbar in properties and moving it up, windows key does not reaveal start menu)
multiple errors come up when the computer is booted
The PC restarts itself when the windows folder is up but i can access it and regedit from my PC when his is the slave drive so that is how i have been working on it.
and the computer obviously has alot of worms and trojans on it.
I hope you can help me out a bit... thank you for your time :)
