How do you restore the Win XP SP3 System Registry after it was modified and all backups deleted by the Malware Antivirmore?

You can't. There's nothing to restore from if all backups were deleted.

What you should have done while your system was clean was download some free "disk imaging" software, buy an external usb hard drive, and copy your entire system drive on to the external drive for backup purposes.

Your only option now is to re-install Windows completely with a factory recovery disc or Microsoft Windows CD, whichever you have.

Thank you for your answer. I recently bought this computer on Ebay and have no disc of any kind. It was OK when I got it. It is a Dell Precision M90 Laptop with Intel Core 2 T7200 @2.00GHz CPU with 2.00 GB of RAM running Win XP SP3. I have a few things on it that would be inconvenient to reinstall but I may have to live with this. The System Registry should not contain much beyond basics. I was hoping to download basics and avoid the need to buy a disk. Resetting to the Dell factory settings did not work.

I have downloaded and run about 10 anti-malware programs from Cnet using Safe Mode. In addition to finding each other they have found over 100 Trojans, Keystroke lagers, backdoors etc. The new ones find less but are still finding malware programs. Attempts to download anything from Microsoft are blocked with the message that the Administrator has a policy not to allow the download. I don`t know how to change this policy. I have also been unable to download a full antiviral program or a different operating system. I did download Firefox which works in safe mode but with the same problems as Explorer. I can do nothing useful except in Safe Mode.

I had hoped to avoid reformatting my hard drive. I would like a complete solution and wonder if I am safe doing anything less.

If I do have to buy a disc exactly what should I get?
