It's now a fact for one of our sites that Panda 2.2 was in favor of scraper sites. Malware sites blocked immediately by my computer security rank on Google with the full copy of our site front page (as seen on G cache) I can not enter these sites with spammy URLs but can view the contents using G cache. One of them prompts download of a computer scan program with a dialogue popping up!
Its an attack, really! It was not so bad a couple of weeks ago!
You know what? That does it Google, you are obviously becoming a malware and using you may harm my computer! Checked bing, these sites don't exist it the index.
