Bad day

Today, i'm surfing websites. Suddenly appear a message that told me, updates for my free AVG antispyware were completed. I thought it was same as everytime i'm update, but today is different. After the message, i heard a sound and i realize that my profile are fully deleted. There are no more Quick Luanch toolbar, no shorcut in my desktop, and no profile for my Mozilla Firefox. Very bad day because i really forget to save my profile and my restore was turned off. That a big lesson for me to always update my profile.
