Today I suddenly encountered a problem, the last thing I remember i did before the problem occurred was that I was installing a game from the Steam, the game asked to install Nvidea Physx, after that, the current problems happened (without any error showing up):
- Can't see task manager when i right click my task bar or even after pressing CTRL+ALT+Del.
- I managed to activate task manager from gpedit.msc but it gets disabled automatically.
- Can't access the regedit.exe (says deactivated by administrator).
- The CPU is always higher than 65%. Random processes (even like Firefox, adobe reader..) takes around 50%, when i kill it, another random process takes 50%..
- I tried scanning my PC (and I'm still doing it again) with Malwarebytes and have Quarantined many suspicious things but all the problems before remained.
(notice that I'm doing all this using my only administrator account which was working fine 4 hours ago).
- I activated the default Administrator account (which is hidden by default) but the same problems are happening even with it.
- I tried doing a system restore but it showed an error after the system gets restarted (an error with a 80070005 error code which looked unhelpful to me).
- Also the SFC scannow terminated without any problem.
I'm really clueless now, it looks like I have lost all my administrator privileges in a glimpse.
