BSOD During System Restore, error 0x000000d1

OK probably a wise decision, good clean system to start again with

If you dont have updated install media including SP1 updates i would download updated copy of win iso from here just be sure to get the same version as you are currently running and have a key for (or it wont work) ie Home Premium, Profesional etc. Have a look through these tutorials for some install guide not sure which one applies to you but scan them all if you have time
Clean Install Windows 7
Clean Reinstall - Factory OEM Windows 7
Clean Install with a Upgrade Windows 7 Version

There is a general concensus around this forum regards AV, we recommend using Microsoft Security Essentials - Microsoft Windows with the inbuilt windows defender firewall & Malwarebytes : Malwarebytes Anti-Malware removes malware including viruses, spyware, worms and trojans, plus it protects your computer as the on demand scanner for malware, just be careful when installing to uncheck the start free trial box to give you the non expiring free version. We see to many problems/BSODs relating to AVG and Kaspersky etc.

I would recommend when you get your system installed be sure to create a system image for future use so if any problems you have an image to restore from, its up to you and how much storage space you have but i take several, one of the vanilla install and more when i have added in users and installed programs and stuff then you have always got the choice to go back just be aware if you create more than one you need to rename the first backup before creating another one in the same location or it will overwrite and leave you with one backup

System Image Recovery
If your not installing from original media (dvd) then make sure you create a recovery disc (you get the option after creating a system image) then you always have bootable recovery options
