Webstats and pop-ups ….Need a new solution fast

I have been using Webststats ever since I started blogging over 1,5 years ago. It always worked fine for me and gave me enough statistics to keep me motivated so to say. Unitil they were taken over … now it i fully commercialised with pop-ups and stuff and I rightfully get a lot of complaints about it. So …I need to get rit of it asap.

Can anyone give me a good suggestion for a comprehensive counter, perferbly free ?
