Is your computer as protected as it can be? Do you even know? One of the most important things to do to keep your computer save is to have the latest versions of software on your computer. Specially software that interacts with the web.
There are notices all over the place for "Free" scans of your computer. Beware! Many of these companies show many false positives and make your computer look worse than it is and then ask for money to fix it.
I have found a company that will to an honest scan for Free. Their name is Secunia and the link to their free scan is http://secunia.com/software_inspector/ . When you get there, click the Start Now button.
You will end up with a list of recommendations of software on you system that are vulnerable and instruction on what to do about it. I suggest you run this test every couple months. And it's FREE.
Contact me if you have any questions.
