AVG makers of antivirus program LinkScanner, noticed a disturbing rash of nearly identical Facebook profiles aimed at infecting users’ computers with spyware.

AVG’s research chief Roger Thompson said that LinkScanner users had reported "rogue spyware attacks" from a large number of these profiles. He postulated that the fake profiles were created automatically, which would indicate that someone, somehow has figured out a way around the ReCaptchas used to protect Facebook from bot-created content.

Here are a few screenshots Thompson posted. Please note that all the fake profiles he reported showed the same main image:

"Facebook will deactivate all these accounts as quickly as they find them, but it can’t be an easy thing for them to find."

Yahoo recently launched Know Your Mojo, a site that claims to tell you what kind of “social mojo” you possess by analyzing your Tweets, but actually appears to do basically nothing. Yahoo hasn’t had the greatest luck with social networks recently, with its Indian social network, SpotM, shutting its doors less than a year after its launch.

Yahoo launched its microblogging product Yahoo Meme, in Spanish and now in English also.  Yahoo had previously launched a Portuguese language micro-blogging product, Yahoo Meme, that drew similarities to Twitter and Tumblr. And on second glance, it seemed to be a mediocre competitor to Twitter, Tumblr and other micro-sharing services in terms of its offerings and features.

How Yahoo Meme works: you create an account and it starts you off with an empty blog that you can fill with text, images, videos, music or a mixture of those things. All you can add to your blog – apart from the content – is a title, a 100-character description and an avatar. You can also create a comment thread underneath the content you post, which was a feature that was missing when we reviewed Yahoo Meme previously.

Like Twitter and Tumblr, you can search other people’s public accounts and follow them, with updates from these users appearing in your stream. You can also ‘Repost’ anyone’s entry, similar to the ‘Reblog’ feature that’s integrated into Tumblr. But the micro-blogging service seems lacking in its features and its potential to surpass its competitors.
