I didn't delete the key you mentioned in HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon. I did delete the key that's in HKCU\Software\Microsoft\Windows NT\CurrentVersion\Run.
To be honest, if I didn't stop it, it would have encrypted all of my files. When I stopped it, I saved about half of them. But it still got around 200,000 files screwed up (mostly documents and installation files).
The virus encrypts all (.asm, .asmx, .jpg, .pdf, .txt, .rtf, .doc, docx, ppt, pptx, xls, xlsx, htm, html, .js, .css, .vbproj, .djvu, .frm, .cdr, .cdx, .php, .phpr, .phprt, .phpyt, phpyyt, .cer, .chm, .dfm, dpr, .key, .pas, .vbp, .wri and .xfm) files.
Did the virus total scan help?
