The whole process was fairly simple: people using Google or other search engines looking for certain Ford information were assaulted by a number of malicious websites. Once the visitor entered the page, a fake video asked him to download and install a video codec in order to be able to play the multimedia content.
Basically, the downloaded software acts just like any regular antivirus application but,
There's only possible solution to block these attempts: refuse to download and install any potential dangerous application that comes from suspicious websites. Furthermore, Ford has already confirmed that it is currently working with Google and other search engines to eliminate the malicious websites so they should all disappear in a few days or so.
Meanwhile, it should be a smart choice to update you antivirus and stay away from unknown websites. Antivirus companies have already started updating their solutions with the "antidot" so, in case you use such an application, you should remain on the safe side for the time being.
