Hello,
I seem to have the same problem as others with aswrvrt.sys. Can’t enter safe mode, BSOD, etc. It happened last night after a windows update.I have followed the directions poster here:
http://forum.avast.com/index.php?topic=120531.0
And attached is the FRST document. Just out of curiosity, what magic do you do? Pull it off the whitelist? I don’t have the knowledge to mess around with it myself, but I am genuinely curious.
Thanks for your help!
Nope, I just disable all the registry keys for the Avast services so a re-install will be required
I thought MS had pulled that KB
Download the attached fixlist.txt to the same USB as FRST
Run Frst as before and press fix
On completion try a normal reboot
That did the trick. I have uninstalled AVAST, made sure the system was updated, and then reinstalled AVAST. A couple of trial boots and she still works.
You are indeed a miracle worker.
Thanks again!
My pleasure, keep safe
I have similar issue (can’t access safe modes or system recovery and hangs on aswRvrt.sys) and wanted to already come prepared with first log and all… except that I can’t even make the first log. When I run the booting USB, it hangs on “Searching for Windows installations”. I’m about to cry lol 
Searching for windows installations does not sound good, what version of windows is this
Windows 7 64. I can get to “Select input language” screen, then in next screen see that it shows Windows 7 (yet 0 MB) and then it starts “Searching for Windows installation”. 
There may be a problem with the boot config or MFT

Once the USB has burnt then
[*]Download Farbar Recovery Scan Tool and save it to the flash drive.
[*]Reboot your system using the boot USB you just created.
Note : If you do not know how to set your computer to boot from USB follow the steps here
[]As the Programme needs to detect your hardware and load the operating system, I would recommend a nice cup of tea whilst it loads 
[]Your system should now display a Reatogo desktop.
[]Locate the flash drive and run FSRT
[]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.
[*]The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.
Followed the instructions very closely, the USB got created without any problems but it just doesn’t seem to load what’s on it. I definitely set up booting in Bios correctly since I already booted from USB today (in attempt to make log like I said earlier), but doesn’t work on this newly created USB It tries to load windows even though USB with Reatogo is on Priority to load
Managed to get Reatogo to run after I just burnt a good old CD instead of USB. However, got blue error screen during loading Reatogo (after XP screen) that said there there’s been a problem detected, to check for viruses and harddrive etc + error: STOP: 0x0000007B (0xF78DA528, 0xC0000034, 0x0000000, 0x00000000)
Got through error screen after changing SATA mode to IDE in Bios. Tried running FRST but it says “FRST.exe is not a valid win32 application”. One problem after another Tried opening up OTLPE but when it asks me to select Windows folder, the Local Disc icon expands to nothing, as if there wasn’t anything on Local Disc
EDIT#2873632: (sorry for being annoying ) I also tried just wiping everything clean and restoring to factory settings however my ACER eRecovery was getting stuck at very first “Please wait” screen and goodle fu said “your HDD is dead”. Which made sense with the empty Local Disc when trying to open OTLPE. But then I tried eRecovery again but with IDE mode for SATA instead, and it atually went through to another screen (in eRecovery). So my HDD is not dead? Really scared to do anything
hi PetW,
essexboy will get back to you as soon as he can, so please be patient. At least you seem to have a working hard drive for now.
Ahh sorry, didn’t wanna rush anyone, was more of brainstorming to myself lol. Since I was able to get the laptop at least somehow functional, I’m attatching FRST log (as following in steps in post #4 here)
OK we will try this first
Download the attached fixlist.txt to the same location as FRST
Run FRST as before and press fix
On completion reboot to normal windows
Did as instructed but got the same BSOD when trying to get to normal Windows. Should I try Safe Modes?
Yes try safe mode. What did you do prior to the non booting ? Windows updates ?
Safe modes didn’t work (though they get stuck at classpnp.sys now). I don’t think I had any Windows Updates since I specifically turned off auto updates few weeks ago. Was sitting on internet, youtube, streaming tv shows. Turned off normally, after getting back from work the next day the laptop wan’t starting. Could just do reset to factory settings since I can access it now, have my files backed
Using OTLPE to back up the files and then resetting the system would probably be the best bet now
Doing it now. Thank you so much for all help and patience with me. Gonna try to get the hard drive check anyway, maybe it really has some defects and just temorprarily got revived
hello essexboy,
I have the same problem as the other people in this thread.
could you help me out? (i know it has been a long time since this thread has started but you would realy help me out here!)
the FRST document is attached, i’m running windows 7 x86
thanks in advance!
Lets try the easy way first
Download the attached fixlist.txt to the same location as FRST
Run FRST and press FIX
On completion try a normal boot
thanks for the quick update, but I chose to just re-install the whole thing, there wasn’t that much data to begin with,
sorry for the work you did…
