Can Facebook use my name and profile picture in ads?

Blog moved. I have a new home now at Do update your bookmarks :)
There were many speculations related to Facebook using users profile picture and social data in their own advertisements. For people concerned about their privacy please read the how to blog from F-Secure turn of this feature.
If you are a Facebook member and like a Facebook page and/or mention a Facecbook page in a wall update, Facebook can use your name and possibly your picture in ads that are shown to your friends.
In fact, your name might be appearing in Facebeook ad now saying that you like a certain brand. Facebook opts everyone into Facebook Ads. And you probably know that because you’ve read Facebook’s Statement of Rights and Responsibilities so carefully
You can opt-out of letting Facebook use your name or profile picture  in ads served to your friends by going to Account.

Check Your Browser's Security Level

Blog moved. I have a new home now at Do update your bookmarks :)
Wide spread use of social networks and web based services has made web browsers one among the of the most used software, which also made them the weapon of choice for spammers,phishers and hackers. Even people who insists to keep their system up to date, forget to update some of the  browser components( browser add-ons/ plug-ins etc.) as these may not have an auto update feature.

Qualsys has released a free service that will allow you to check you web browser security. It supports all the main stream browsers ( Firefox,Chrome,Opera,IE and Safari) on a variety of platforms like Windows ( XP,Vista etc..), Mac and Linux. Though the service is in beta stage in some platforms and browsers, its still worth to check them out. Detailed list of supported platforms and plugins are available here.

Browsercheck will ask you to install a plugin to continue scanning (I was not asked to install plugin in Ubuntu with Chrome as well as FF4, guess the beta versions is not full fledged yet ), the plugin is signed by Qualsys. Install it to continue (read the FAQ to know the need for installing plugin and to know their privacy policy).
Once installed you are good to go to check your browser's patch level.Click the scan now button.

Browser check will scan your browser, plugins and addons against known vulnerabilities and give you a report with installed plugin/addon details along with its patch status. Detailed status report descriptions are available in FAQ, but as a rule of thumb "Green" means fully patched and "Red" means vulnerable. 
Clicking the button will give you more details regarding the problem and possible remedy. Mostly it will be a link to download the latest version.
After fixing all the security holes in your browser, I strongly recomment to scan it once again to ensure the security, as some times plugins/addons comes with additional software( for eg google toolbar) that may ruin the security of your browser.
On a final note  as with any security solution, browsercheck is not a single self sufficient solution for online security, the ultimate security comes with awareness.
Happy browsing with a secure browser :)
