Hello,

I have a laptop which has odd startup behaviour and which reflects the behaviour of another laptop, my sisters laptop that I was fixing.  I copied files from my sisters laptop to my laptop but scanned her disk before hand, but think now I've copied across a boot sector virus or something worse.

 

The beheviour of my laptop is when I press the start key, the button and power light come on, the fan comes on at a low speed, the dvd is checked, and then it repeats this behaviour with the lights going off, then after about 30 times on/off, it finally comes on, with the fan constantly on. But no screeen, no boot.

 

My sisters laptop reported almost the same behavioir. My laptop Windows 10. The other laptop Window 8.

I've moved this to the more suitable forum,

Am I infected? What do I do?

This is now closed.

Greetings PearlySoames and :welcome: to BleepingComputer's Virus/Trojan/Spyware/Malware Removal forum.

My name is Oh My! and I am here to help you! Now that we are "friends" please call me Gary.

If you would allow me to call you by your first name I would prefer to do that.

===================================================

Ground Rules:
  • First, I would like to inform you that most of us here at Bleeping Computer offer our expert assistance out of the goodness of our hearts. Please try to match our commitment to you with your patience toward us. If this was easy we would never have met.
  • Please do not run any tools or take any steps other than those I will provide for you while we work on your computer together. I need to be certain about the state of your computer in order to provide appropriate and effective steps for you to take. Most often "well intentioned" (and usually panic driven!) independent efforts can make things much worse for both of us. If at any point you would prefer to take your own steps please let me know, I will not be offended. I would be happy to focus on the many others who are waiting in line for assistance.
  • Please perform all steps in the order they are listed in each set of instructions. Some steps may be a bit complicated. If things are not clear, be sure to stop and let me know. We need to work on this together with confidence.
  • Please copy and paste all logs into your post unless directed otherwise. Please do not re-run any programs I suggest. If you encounter problems simply stop and tell me.
  • When you post your reply, use the Replytopic.jpg button instead.
  • In the upper right hand corner of the topic you will see the Followtopic.jpg button. Click on this then choose Immediate E-Mail notification and then Proceed and you will be sent an email once I have posted a response.
  • If you do not reply to your topic after 5 days we assume it has been abandoned and I will close it.
  • When your computer is clean I will alert you of such. I will also provide for you detailed information about how you can combat future infections.
  • I would like to remind you to make no further changes to your computer unless I direct you to do so.
===================================================

Now that I am assisting you, you can expect that I will be very responsive to your situation. If you are able, I would request you check this thread at least once per day so that we can try to resolve your issues effectively and efficiently. If you are going to be delayed please be considerate and post that information so that I know you are still with me. Unfortunately, there are many people waiting to be assisted and not enough of us at BleepingComputer to go around. I appreciate your understanding and diligence.

Thank you for your patience thus far. We can only work on one computer per Topic so let's deal with the Windows 10.

Please attempt to run this program for me.

===================================================

Farbar's Recovery Scan Tool

--------------------

For this step you will need a USB flash drive and start on a clean computer.
  • From a working computer please download Farbar Recovery Scan Tool and save it to a flash drive. You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.
  • Plug the flashdrive into the infected PC and follow the 2 step process below to enter the System Recovery Options using one of the three options listed, then running Farbar's Recover Scan Tool
----------

Entering into the System Recovery Options

Option #1

To enter System Recovery Options from the Advanced Boot Options:
  • Restart the computer.
  • As soon as the BIOS is loaded begin tapping the F8 key (possibly another key) until Advanced Boot Options appears.
  • Use the arrow keys to select the Repair your computer menu item.
  • Select English as the keyboard language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account and click Next.
Option #3

To enter System Recovery Options by using Windows installation disc:
  • Insert the installation disc.
  • Restart your computer.
  • If prompted, press any key to start Windows from the installation disc. If your computer is not configured to start from a CD or DVD, check your BIOS settings.
  • Click Repair your computer.
  • Select English as the keyboard language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account and click Next
----------

Running Farbar's Recovery Scan Tool in System Recovery
  • Once you are in the System Recovery Options menu you will get the following options:

Startup Repair
System Restore
Windows Complete PC Restore
Windows Memory Diagnostic Tool
Command Prompt

  • Select Command Prompt
  • In the command window type in Notepad and press Enter.
  • The notepad opens. Under File menu select Open.
  • Select Computer and find your flash drive letter and close the notepad.
  • In the command window type e:\frst (for x64 bit version type e:\frst64) and press Enter
    • Note: Replace letter e with the drive letter of your flash drive.
  • 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.
===================================================

Things I would like to see in your next reply. Please be sure to copy and paste the information rather than send an attachment. :thumbsup2:

Dear Oh My!

 

Thanks you for your time. But I've since sent the laptop to Acer for repair. I couldn't boot it, and suspect the motherboard had failed in some way.

Please close the topic.

 

Bob.

It appears that this issue is resolved, therefore I am closing the topic. If that is not the case and you need or wish to continue with this topic, please send me or any Moderator a Personal Message (PM) that you would like this topic re-opened.
