Malwarebytes deleted a critical component....
A little over a week ago, I was trying to rid my desktop of Personal Guard 2009. The guys over on the Malware forum at techguys.org were helping me there. The last 2 scans that I needed to do to ensure I was clean was to do a Malwarebyte scan and an OTS scan. Malwarebytes went through its scan, came up with 3 files that it wanted to delete and then reboot. So it did...everything but reboot. On reboot the computer went to the Dell screen then a blue screen which read something like, "A problem has been detected and windows has been shut down to prevent damage to your computer. .......Technical information: ***Stop: 0x0000007B (0xF9679528,0xC0000034,0x00000000, 0x00000000)"

The next day, we found out that Malwarebytes was giving a false positive and deleting atapi.sys from my system. I contacted the tech guy there at Malwarebytes and his fix was to use my OME reinstallation cd to do a repair install on Windows XP. So, I inserted the cd and followed directions. 30 hours later, the screen still showed 32 minutes left to complete setup. I turned the computer off and tried again. This time it went fine but I got a lot of copy errors that I had to cancel (Setup cannot copy the file migregdb.ex_. etc.) In the end, windows booted, all of my settings looked to be intact. I shut it down with the intentions of coming back this morning and connecting the desktop to the internet so I could download the service packs. However, this morning the computer was in a loop, Dell screen to Windows screen and back to Dell. I tried to boot to Last Know Config. but it just went back to the loop. Same with Safe mode.

Right now I am attempting to repair install again. Does anyone have any other suggestions??

Btw, it is a Dell Dimension that use to run Windows xp home edition. The reinstall was for service pack 1a.

Hey galmc

This is a frustrating problem. Before we try and fix anything however I suggest we back up all your data first. This is a good tutorial to use. However as Ubuntu has recently updated, this is the version of ubuntu they want you to use. The version they link is the latest version.

Direct Download for Ubuntu 9.04

Once your files are backed up, we can work on getting your computer up and running.

Post with any question

Importing the registry keys again may be the solution you are looking for:

Malwarebytes Atapi.sys and Registry False Positives

To quote from the responses section under the article itself ....
Once the computer has started up and you are in Windows, re-import the keys ......... The reason this needs to be done is that when you start the system and the registry is loaded into the CurrentControlSet, it may not save it when you shutdown after the first time, then your loops will start happening again.

Thank you both for your replies. I really appreciate them.

Powerjuice, thanks for the suggestion of backup. I went ahead and bought an external harddrive and backed up all of my files before I started trying any of these scans. I am so thankful that I went ahead and did that!! I don't think that I lost any files in the repair but I would have been a basket case if I had not known that all of my pictures were safely tucked away.

I've also seen several references to Ubuntu while working on getting this computer going. I'm going to have to research that more.

AustrAlien, thank you for your link! Very straightforward so that even I could understand. Fortunately, the second repair install worked great and I was able to download SP3 to windows. Everything seems pretty stable now and I have rebooted the computer about 4 times now with out a hint of a problem. (Although, I was holding my breath the entire time. ) If the repair install had not worked, I would have used that website. I think that I could have followed it quite easily.

Thank you again for your time and your suggestions. :thumbsup:
