Solved Windows changing settings and deleting my files

[juice]

Graphic Problem

When I turned on my PC today it ran CHKDSK automatically before loading W7 (I did not not tell it to run). When it was finished, windows loaded up and some of my settings had changed such as mouse speed, desktop backgrounds, cleartext settings etc. Also when I move a window a black outline box appears (see attachment) and I don't know how to fix this.
Can anyone help me out? Also has anyone else had this chkdsk issue?

That's really strange! Had system abruptly turn off sometime - bsod, blackout, etc?!...
I would run a FULL SCAN "offline" antivirus such this one Avira AntiVir Rescue System
After that, I'd install Malwarebytes and should do a full scan too - Malwarebytes
Then, redo setthings as you preferred.

Let us know the results.

When I switched my PC on today it ran what I think was CHKDSK even though I had never instructed it to do so. The text said something about deleting and retreiving bad files or something. When Windows 7 booted up after, some settings had changed:

• Mouse tracking speed changed
• Personalisation settings changed and saved as 'untitled theme'
• Some changes to windows graphics settings
• 'Cleartext' turned off
• Firefox browser no longer set as default browser
• At least one file (that I have noticed) has been deleted from my hard disk

This seems pretty worrying security-wise. The software I run is Spyware Doctor with Antivirus which has found a few low-risk spywares but nothing major.
Any ideas??

It almost sounds like someone else has taken control. Do you share your computer?
