finallyfast.co.uk – scam or useful service?

I recently saw an ad on tv for finallyfast.co.uk which offers a “pc speedup service”. The ad immediately made me think it was a scam because of the way it was done.

A quick google shows I am not alone:

• finallyfast.com | Web Safety Ratings from McAfee SiteAdvisor – doesn’t rate it as bad but user comments seem to
• Mrkass’s Weblog | beware of pc speedscan
  
• Bill Mullins’ Weblog | Finally Fast.com – Fast Scam! Free Alternative Software
  
• PC Advisor| consumerwatch – Spyware remover advertised on the telly

There is also a youtube video of the (US version) ad along with some user comments which give a feel for user feedback

I would recommend extreme caution when going to this site, and would certainly not recommend it to anyone
