> Security firm BitDefender said it had detected infections contained in the news feeds of around 20% of Facebook users<p>I've seen a lot of malware posts, but 1 in 5 users? I'm skeptical based on my biased sample.<p>> BitDefender arrived at its figures by analysing data from 14,000 Facebook users that had installed a security app, called safego, it makes for the social network site.<p>Well there you have it, their sample is clearly more biased. A large number of people don't install apps at all. Some people install apps indiscriminately... including both malware and "safego".
