I have Windows 7 x64 and cannot boot into it because aswVmm.sys is missing or corrupt. I can't get into any of the Safe modes or access the command prompt. I don't have the installation disc on me either.

I've asked someone to help you. They'll need to uninstall Avast. You'll have to re-install it.

Download the following three programmes to your desktop :
 
 
1.  Rufus 
 
For 64bit systems  
2. Windows 7 64bit RC I will pm the link
3.  Farbar Recovery Scan Tool x64 
 
Insert the USB stick Then run Rufus
 
Select the ISO file on the desktop via the ISO icon. 
 
Press Start Burn

Then copy FRST to the same USB   
 
   
 
 
 
Insert the USB into the sick computer and start the computer.  First ensuring that the system is set to boot from USB 
Note: If you are not sure how to do that follow the instructions Here
 
 
When you reboot you will  see this although yours will say windows 7.
 Click repair my computer  
 
 
Select your operating system  
 
 
Select Command prompt 
 
 
At the command prompt type the following  :
 
notepad and press Enter
The notepad opens. Under File menu select Open
Select "Computer" and find your flash drive letter and close the notepad. 
In the command window type e:\frst64.exe and press Enter 
Note: Replace letter e with the drive letter of your flash drive. 
The tool will start to run. 
When the tool opens click Yes to disclaimer. 

Press Scan button. 
It will make a log (FRST.txt) on the flash drive. Please copy and paste it to your reply.

This will remove Avast and it will need to be reinstalled on completion

Download the attached Fixlist.txt to the same location as FRST
Run FRST and press Fix
On completion a log will be generated please post that
Reboot to normal mode
