Viruses and worms

I have Windows 7 x64 and cannot boot into it because aswVmm.sys is 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. Please help!

Please download Farbar Recovery Scan Tool x64 and save it to a flash drive.

[*]Plug the flashdrive into the infected PC.
[*]Restart your computer and tap F8 to bring up the Advanced Menu, then click Repair your computer
[*]Follow the prompt to enter keyboard input method, and then the prompt to enter a password. If the machine does not have a password, simply click Enter.

In the next menu, use the arrow keys on the keyboard to highlight Command Prompt and press Enter.

[*] In the command window type in notepad and press Enter.
[*] When notepad opens, click File and 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 attach it to your reply.

Download attached fixlist.txt and save it to your USB flashdrive as fixlist.txt

Boot into Recovery Environment

Start FRST in a similar manner to when you ran a scan earlier, but this time when it opens …

[*] Press the Fix button once and wait.
[*] FRST will process fixlist.txt
[*] When finished, it will produce a log fixlog.txt on your USB flashdrive.

Exit out of Recovery Environment and post me the log please.

Try to boot Windows normally…

That fixlist will target all of Avast! so you can boot. You’ll need to re-install AVAST!. However, all other files will be fine.
