FYI, I've mentioned that I use Spybot Search&Destroy, Malwarebytes' Anti-Malware and AVG Anti-Virus with very good results.  Cross my fingers, absolutely swear by them.
 
Well I got an email from AVG regarding a new app called RegistryBooster.  And, since it allowed one free scan I thought I try it.  Damn, sucker came back with nearly 500 registry errors.  The free offer would only fix 25 so I bought it.  Not only did it fix the errors but I can see a SIGNIFICANT improvement in performance too.
 
For you skeptics, I reviewed the log afterwards and they were indeed legitiment errors.  Good stuff.
