Hello.
I can not boot my pc with Windows Vista and Avast antivirus.
In normal mode does not start, and failsafe mode remains aswrvrt.sys loading the file and restarted …
Sorry for my poor English.
Thank You.
Greetings.

Hola tebilon. Bienvenido al foro.
Usa el enlace que dio Para-Noid
https://forum.avast.com/index.php?topic=53253.msg451454#msg451454
pero desplazate hasta donde dice If you cannot Boot the computer y sigue las instrucciones. Necesitaras otra computadora para crear el CD. Por favor sigue en ingles. Yo estare atento si no entiendes algo. Lo mas seguro recibiras ayuda de essexboy.
********** English**********
Use para-Noid link but scroll down to where it says “If you cannot Boot the computer”. Follow instructions. You will need a funcinal PC to create the CD. Please continue in English. I will be around to help if you do not understand. Essexboy will help you.
Is it 32 or 64bit Vista.
Do you have access to another computer and a USB stick of about 4GB
Hello
It´s 32 bit.
I have access to another computer and a USB stick with 4GB.
Thanks
Download the following three programmes to your desktop :
For 32bit systems

3. Farbar Recovery Scan Tool
Insert the USB stick Then run Rufus

Press Start Burn

Press Scan button.
It will make a log (FRST.txt) on the flash drive. Please copy and paste it to your reply.
Sorry for not replying yet, but it is still impossible to start the pc. I think it will be a problem with the HD. I had never given problems, but it does not work well.
I’ll keep trying and will comment the results.
Thank You.
regards
Will you follow Essexboy instructions and post FRST log ?
I finally managed to run the FRST.exe, but was starting to recovey the pc, not the USB.
Here I leave the log.
Thank You.
A greeting.

OK using the recovery console select command prompt as before.
Then type in the following command and press enter :
chkdsk c: /r
On completion try a normal boot
It may take running chkdsk more than once…reboot each time.
Friendly thought…if above does not work then “offline” SFC.
May have to run Startup Repair from Console after above too.
