Hi all.
I had Avast running for some time with no problem. As of 4/5 days ago, I cannot boot into any form of Windows inc. safemade. When attemting safemode, I see that it is getting stuck at aswrvrt.sys and then the BSOD happens.
Please, if anyone can advise.
I did search, and I found the reply of Essexboy, but some of the links to the software seem to have expired.
Many thanks.
Is this a 32 or 64bit windows 7 ?
Win 7 32bit
ps, thanks for answering so quick!
Download the following three programmes to your desktop :
Insert the USB stick Then run Rufus

When booting from the USB, I keep getting a window titled Windows boot manager which says windows failed to start.A recent hardware…

status: 0xc000098
Info: Windows failed to load because a critical system driver is missing, or corrupt.
Was faulty USB, have tried another and now in process…
Following the error scan, its already 15 minutes:
Attempting repairs…
Is this normal?
Please find attached.
Initially I will try a restore
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
Here goes:
Should I restart now?
Ok, I restarted and it worked. Thanks a mil!
Anything else I should do so that this doesnt reocur?
It really depends on what occurred just prior to the BSOD
No idea… I will wait and see if it happens again.
Again, you are a legend, thanks so much!
No problems, glad to be of help
Just one thing, this is the list of restore points:
Restore point made on: 2014-02-23 12:21:09
Restore point made on: 2014-02-23 13:44:25
Restore point made on: 2014-03-03 10:30:17
Restore point made on: 2014-03-11 04:17:13
Restore point made on: 2014-03-12 11:46:44
Restore point made on: 2014-03-13 13:13:53
Restore point made on: 2014-03-17 11:50:08
Restore point made on: 2014-03-20 13:39:41
Any reason you chose 2014-03-11 for the fixlist?
On windows Vista and up we are unable to externally invoke a specific restore point, so what I do is use the last registry backup to reset the system 
Essexboy, learning moment here for me.
Can you not do a system restore from Command Prompt in Windows 7 ? (eg. rstrui.exe,)

Also, not sure if OP had recovery CD but if so could he have used system restore point ?..attached example screen shot.
…or is it that FRST being on USB stick (external) has limits ?
Nine times out of ten the system restore from the CD will either lock or freeze, so the last reg is the simplest method that is 90% guaranteed to work
