It happens sometimes, like when you search for something on Google.com, in the list of sites displayed, some with the warning should appear “This site may harm your computer“. These sites are classified by Google as dangerous sites for your computer. Sites of spam, sites with virus, keyloggere and other wonderful things that would affect the proper functioning of your computer and the security of your personal data.
Someone called me this evening and told me that he can no longer access from Google, the official website of Orange Romania (orange.ro). It has tasted “orange” on the google.com search engine and noticed the message “This site may harm your computer“. WTF?!
Nothing abnormal. Actually at that time they were all sites are infected. According to the search engine google.com (the largest With), all sites were infected. Including theirs :)
