Dunno if this is real and/or effective, but here are some manual removal insructions I found:

To delete Vista Antispyware 2011 registry keys, open the Windows Registry Editor by clicking on the Windows"Start" button and selecting"Run." Type "regedit" into the box and click "OK."

Finally, to completely get rid of Vista Antispyware 2011, you must manually remove other Vista Antispyware 2011 files. These Vista Antispyware 2011 files can be in the form of EXE, DLL, LSP, TOOLBAR, BROWSER HIJACK, and/or BROWSER PLUGIN. For example, Vista Antispyware 2011 might create a file like
