The SFC scan shows the following problem...

I'll post a fix protocol for that in a few minutes.
As far as your Explorer problems are concerned, I'd be thinking about either disk corruption, or malware -
Click on Start > All Programs > Accessories
Right-click on the Command Prompt entry
Select Run as Administrator and accept the UAC prompt - the Elevated Command Prompt window should pop up.
At the Command prompt, type
CHKDSK C: /R
and hit the Enter key.
You will be told that the drive is locked, and the CHKDSK will run at the next boot - hit the Y key, and then reboot.
The CHKDSK will take a few hours depending on the size of the drive, so be patient!
After the CHKDSK has run, Windows should boot normally (possibly after a second auto-reboot) .
Please download and install Malwarebytes Anti-malware (free version) from http://www.malwarebytes.org/products/malwarebytes_free/ - UNtick 'Enable free trial of MBAM PRO' at the end of the installation - and update it, then run a full scan in your main account, and Quick scans in any other user accounts.
Delete everything it finds
