BTW, if you use scandisk to mark bad clusters, I find it best to run the program with the /NOSAVE option. In my case, the bad clusters are all in the area of the disk that has no files. The only file actually affected was the mysterious email with an attachment...which I had deleted.
IMHO Rather than trying to save the file that was infected, it is much better to restore or lose the affected file than having the program try to save the file. BTW, scandisk is still running....my poor little laptop. I hope it gets well soon.
