Avast Rescue disk 2012 / Avast update
« on: November 23, 2012, 04:35:49 PM »
I update my Avast software recently and ran a full scan on my computer, The scan found multiple trojans and after the scan a message said to reboot to elliminate the malware. I re-booted and the computer made the normal startup noises but I got a blank screed (black). It re-booted several times and got the same result.

So my question is, If I get an Avast Rescue disk will it boot without getting into the bios setup. I can't do this because I have a blank screen
Any help will be appreciated.
Thanks

What operating system do you have ?  And can you burn a CD or have you  a USB (at least 4Gb)

Please print these instruction out so that you know what you are doing

  • Download OTLPENet.exe to your desktop
  • Download Farbar Recovery Scan Tool64 and save it to a flash drive. (64bit system)
  • Download Farbar Recovery Scan Tool and save it to a flash drive. (32bit system)
  • Ensure that you have a blank CD in the drive
  • Double click OTLPENet.exe and this will then open imgburn  to burn the file to CD
  • Reboot your system using the boot CD you just created.
Note : If you do not know how to set your computer to boot from CD follow the steps here
  • As the CD 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.
Note : as you are running from CD it is not exactly speedy
  • Insert the flash drive with FRST on it
  • 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.

Hi,

It seems that the Dell monitor i have went into sleep mode so I could see just a blank screen even when i hit the mouse or any key. So I had had a hdmi cable installed to my TV monitor and I attached it again and now I can see what I was doing again! STRANGE!

Another unusual thing is I decided to run the pc withoout the disc and it booted and a message came up   "Config update stage 3 of 3 , do not turn off computer. So I left it and keeps re-booting, So I turned it off.

Here is the results from FRST:

OK it is a 64bit Vista system and the configuration screen indicates that a windows update is in progress

So what we will do now is install the recovery console and get the system rolled back to an earlier restore point

Download the following two programmes to your desktop :

 
1.  WiNTBootIc
2.  Windows Vista RC 64bit


Extract wintoboot to your desktop
Insert a USB drive of at least 1GB
Run Wintoboot



Drag and drop the Windows Vista ISO to the programme in the space indicated
Tick the Format box and accept the warnings
Press Do It

You will see it progressing



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.
Click repair my computer

 
Select your operating system

 
Select System Restore

 
Select an appropriate restore point
Then once done reboot to windows and let me know if it is OK

Not a problem .. Keep the USB as that may come in handy
