Extremely slow browser sessions Better Srf?

Has anybody heard of malware with the name 'better srf', or close variants?  I have received no relevant messages from Symantec about it.  I have tried to remove it using 'Hijack This' but it cannot be touched.

  That seems suspicious, especially since any online work using my browser (Firefox) is extremely slow, almost unusable.  When I type I can get 4 or 5 letters ahead of myself.  All other operations, like searching and loading, are also slow.

SO, my question is a dual one.  What is bettersrf and could my online problems be a result of an infection by it or something else?
