I have never had a problem with Google, however, I have AVG for protection. H&*
I agree with what sciencewiddow is saying, if you keep your security and firewall up to date it will prevent you from having any problems. Google is just a search engine and the google adds are what site owners pay for to get them on top of the search engine. So if there is a virus on a website then it has nothing to do with google.
I, too found this site through google. I heard to NEVER search the word "free" with what you are looking for--i.e. Free Embroidery Designs :)
I have used google for years as my web search engine. I too found Cute through that means.
Nearly 4 years ago I clicked on a google embroidery ad and found Cute. What a lucky day that was!
