If it was a BSOD Please post from this tutorial:

Make sure to add the BSOD information so we can properly try to solve the problem.

Your problem is virus related. First we need to take care of that.

Use another computer to download Windows Defender Offline. Put it on a CD/DVD or bootable flash drive, and use it to find and eliminate your virus threats.

What is Windows Defender Offline?

Critical error system shutting down (continued)

Followed the link you provided and down loaded Windows Defender Offline to Flash Drive; booted netbook from flash drive and ran Windows Defender Offline in Quick mode.

It detected:
- Virus: Win32\sirefef.r
- Trojan: Win32\sirefef.ah

It was blocked from removing them by Group Policy - Error code 0x800704ec. It placed them in Quarantine and said Remove Immediately. Then it gave the container files.

Since Microsoft Security Essentials discovered 5 suspicious items I decided to run Windows Defender Offline again in Full mode. Its running now.

Please advise next step.

 

[HonorGamer]

Use the computer like normal, and see where that goes.

Also go ahead and try to do another BSOD report.

 

[kegobeer]

Run WDO a couple of times after the full mode completes to make sure nothing is left. Then, boot up and do a complete scan with MSE.

 

[KCav]

Full mode is still running its about 2/3 complete. Will run WDO again, if there are no changes will run MSE with setting to remove items from computer not just put them in quarantine?

 

[KCav]

Its now 4:53PM. WDO has finished running and it found 5 Active severe files; ran Remove and WDO said applied your action successfully.

I have statred another Full scan.

Encyclopedia entry: Win32/Sirefef - Learn more about malware - Microsoft Malware Protection Center

Caution: Win32/Sirefef is a dangerous threat that uses advanced stealth techniques in order to hinder its detection and removal. Particular variants of Win32/Sirefef may also make lasting changes to your computer that will NOT be restored - some system files may be irrevocably corrupted and essential security services may be disabled.

Due to the severe consequences associated with this threat, you may need to reinstall your Windows operating system and other computer programs, and restore your files and data from backup if your computer is infected with any of the following Sirefef variants:

• Trojan:Win32/Sirefef.AA
• Trojan:Win32/Sirefef.AC
• Trojan:Win32/Sirefef.AH

Based on this, you may wish to consider a clean install:

[KCav]

OK, please advise best way to make bare bones installation. System does not have internal CD drive. How should I:
1. Make bootable Flash drive
2. Wipe drive clean
2. Install Windows 7 Ultimate 32 bit
3. Setup basic System configurations

See this post, Golden posted some excellent links for d/l ing & installing Windows from a FD

http://www.sevenforums.com/system-s...d-windows-firewall-service-2.html#post2013524

Install Windows, install a AV, along with Malwarebytes.

After the clean installation, if you make a system image, this will save you a lot of time down the road if something like this happens:

[KCav]

As Golden suggested, I am down loading Windows 7 version ISO from Digital Rivers website. Down load is in progress - it takes 2 hrs 15 minutes. Download is being made to 8GB Flash drive. I have the product key.

Also, I completed description of my netbook in User profile.

Also, I read the second reference you provided, "Backup Complete Computer - Create an image Backup." I would like to create a backup strategy for this netbook. Should I start a new thread for this?

 

[Borg 386]

No need to start a new thread. There are many excellent tutorials on this site.

Here are two tutorials on backup:

Please consider this first. Because of the type of infection your computer has any thing you back up may also be infected. That why have backup's prior to infection are most important.

Down load of Windows 7 Ultimate 32-bit ISO from Digital Rivers has completed.

Down loaded Windows 7 USB/DVD Download Tool. Used the tool to create bootable Flash drive for Windows 7 Ultimate 32-bit.

- have completed reinstallation of Windows 7 from flash stick. Thank you for directions on where to find ISO file and instructions on how to write ISO to flash drive.

I reinstalled and activated Windows 7 Ultimate 32-bit on my netbook, and connect the netbook to the Internet; down loaded and installed 58 updates to Windows 7. The system did not crash during this lengthy process, and it was lengthy. Hopefully, the virus that MSE and WDO found but could not remove is gone from my system.

Next I installed Microsoft Security Essentials, updated it and ran a Full scan. It detected over 140,000 items without finding anything suspicous. After that I down loaded CCleaner and ran it. It found temporay files that should be removed, but there were also items in the Registry that were invalid because the files they used were not found on the hard disk. I let CCleaner remove them.

I discovered an item on my Start menu called Windows Memory Diagnostic. I ran it and it performed 5 cycles and did not detect any problems. However, it has disappeared from my menu. Can someone explain what makes this diagnostic tool appear and then dissappear?

I decided to make an off machine backup using Windows 7 Backup. The file size was only 6.76 GB and the destination was a networked drive on a desktop computer connected my LAN. It looks like less than 10% has transferred in four hours. It seems DTR is to slow to be of practical use. I'm about to terminate the backup.

My netbook has one internal hard drive, a Seagate, Momentus 320 GB SATA. How should I make a backup that can be quickly rinstalled?

I am considering partitioning the drive into two logical drives; one for system files, the other for Data; maybe use 60 GB for system files. That way when I make an image file of the system partition it will be a smaller and consume less storage space. Is this a good idea? Everything works to a degree.
Would you do this? What would you do to provide an efficient means for making an image file of my sysetm partition, and being able to restore it quickly?

I have downloaded and installed Macrium, Reflect, and connected an external USB hard drive to my netbook with a USB cable. I am planning to make a Full backup of my system partition to a folder on the external hard drive. Can someone recommend a better approach in terms terms of time required and space consumed?

Macrium, Reflect has a procedure for making a Rescue DVD, but I need a bootable Flash drive. Does anyone know how I can do this with Macrium's software?

 

[KCav]

- made bootable Flash drive with Macrium Reflect installed on it; used it to backup the netbook's internal hard drive to external USB hard drive.

What software should I use to partition the netbooks hard drive?

You can use Windows to partition the HD or some of these free tools:

Best Free Partition Manager

Generally, for a system image, it's a good idea to put it a External HD (Or DVD's if you choose, just treat them carefully). That way it's isolated and lowers the risk of infection in case you get something.

I would recommend to create a system image on a separate HDD, or a separate partition on a separate HDD, for the best reliability to restore from it. CDs or DVDs are just not as reliable. A scratch one just one of them could ruin the whole image.

Have a look at this tutorial and read it fully, there is a warning section of what you should/should not do:

Try typing "Windows Memory Diagnostic" in the search window that appears after you hit the start button. It should show up again.
