Installation failed to complete.

I recently tried installing Avast antivirus and the installation failed to complete. Now when I try to install it I receive an error stating it has “detected a corrupted avast! antivirus installation on this computer (service ‘aswSP’ is running), thus this installer cannot continue. Please repair your computer first.”
I cannot locate the service referred to.

Did you remove your previous used AV before installing avast?

See here http://www.avast.com/faq.php?article=AVKB11#artTitle

Remove avast…read instructions http://www.avast.com/uninstall-utility

Reinstall http://www.avast.com/download-software

Thanks, the uninstall utility did the job. Everything is fine now.
