Malicious Themes

Hi all,

Sorry for my english, itsn’t my mother language.

I am launching a “professional” website with WP (and I have no knowledge of coding). It will be an internet magazine.

Now I have to choose the theme. A magazine one.

But I red this Why You Should Never Search For Free WordPress Themes in Google or Anywhere Else and I am afraid to get a paid theme (or free theme) with base64 code or with other malicious code (link hiddend links…).

How can I be sure that a theme is really free of malicious code before getting it ?

Which is the best “place” to buy safe templates (like magazines…)?

Regards.
