Lately many *.sk sites got into google or badwarebusters blacklist

Probably because some iframe injections which are detected as threat even when are not there on purpose

Yesterday we had same problem luckily we were at changing database and such so we clean formated server and put new pages in

After control with google tools its clean now we just waiting :)

Have you submitted a review request, either with Google or with StopBadware? That is the only way to request removal from Google’s malware list – a post to BadwareBusters is not enough.
