  1. I accidently ran this over my (C:) drive and cleaned all possible .lsp files, I suspect this shouldn’t have been done and I’m worried, is there any way to restore this action?

    1. No worries. It doesn’t delete lisp files. It just removes virus code from them. It generates a log file on your desktop. You can see the files that are cleaned in that file. Also it backups lisp files with a bak extension before making changes. So, you can easily restore your old lisp files.
