Pc Won't Start: Error C0000034 Applying Update Operation 44 Of...

I had to install a malware remover after catching a trojan, which worked just fine, but when it asked me to restart the computer it will only start in recovery mode and stay stuck on the screen saying "Error C0000034 applying update operation 44 of 62501". If I press F8 when restarting all the options require me to log on as "adinistrator" (the spelling error worries me as well), and it will not accept the password. Have been unable to turn on the computer since without it either getting stuck or at the menus requiring "adinistrator" password. What should I do!

 

I wish it where that simple. I downloaded the programs on a usb drive as directed, and turned on my faulty pc. When it turns on, I continually press F8, it very very briefly flashes:
Initializing Intel (R) Boot agent GE v1.4.10
PXE 2.1 Build 092 (WfM 2.0)
Then:
Preparing automatic Repair
Then:
Diagnosing your PC
Then:
Automatic Repair
Then:
Your PC did not start correctly
my options then are either Restart or Advanced Options
Which brings me to a blue "Troubleshoot" page:
-Refresh your PC - it gets stuck again on Error C0000034 applying update etc. page;
-Reset your PC - haven't tried that as don't want to lose files;
-Advanced Options, which takes me to a blue Advanced options page, whith the following options:
System Restore - log in as Adinistrator (spelling mistake is real), password, password incorrect it isn't)
System Image Recovery - log in as Adinistrator etc.
Startup Repair- log in as Adinistrator etc.
Command Prompte - log in as Adinistrator etc.
Startup Settings - which brings me to:
Press a number to choose from the options below:
1)Enable debugging
2) Enable boot logging
3) Enable low-resolution mode
4)Enable Safe Mode
5) Enable Safe moed with Networking ect ect to n.10
Which doesn't matter because regardless of which one I press it will restart and do exactly the same thing. It doesn't take me to safe mode or the System Recovery Options menu. Very unfortunately
