I will start from the begining.
2 PC's both running W7 both up to date with antvirus Bitdefender Total Security.
I noticed that I could not access cetain webpages including saved favorites. I decided to run a scan and clean up utilities in my antivirus to see if I could solve the issue, no joy.
I tried a System Restore but got an error.
"System Restore failed while copying the registry from the restore point. An unspecified error occurred during System Restore (0x80070570)
I tried different points but the same result on both PC's.
