can you help? I have not found this in vista back up restore center. I have posted more messages on it with another member above
Is this a machine with an actual Windows disc,or are you working from factory, "restore discs"? Because the options and procedures are quite different. A genuine Windows disc has a "repair console", (press "R"), whereas the restore disc may call this a, "non destructive restore. Sometimes there is a "restore with backup option as well".
IMHO, in these situations, you might be better off by doing a "live run" of Linux. (Run a Linux OS direct from a CD without installing it), and copy your data files to another hard drive, external or otherwise. Then reinstall the Vista with a full reformat, install an AV and or other security software, and scan your data files from the other drive for remnants of malware. Your data files may still contain executable files, which could harm or infect the new installation if triggered.
After a bad infection, I don't normally waste too much time trying to clean up the OS installation. I copy the data only to another drive and reformat. This provides a golden opportunity to weed out the crap and unused programs that build up after a time. That's just me though. Your wishes and results may vary.
After you get this straightened out, and your necessary programs installed, consider buying drive imaging software. Keep your data on another discreet drive, or partition. When things go sideways, you just pop in the image discs, and you're up and running again rather quickly.
