Hi, Please understand that I am not experienced as all of you seem to be. I had an experience a couple weeks ago when surfing the net and all of a sudden a pop-up supposedly from windows mail saying that I had picked up a virus. I was suspicious so I did nothing about it because I thought it looked suspicous. Now I am wondering if windows does have an alert message when on websites to alert to dangerous ones. The pop up looked real with the right logo, but it wanted to me to download something to get rid of the virus it said it detected. Then when I closed the window it gave me another warning asking if I really wanted to close the window without removing the virus. I have Vista 62 bit and us avast free. Thanks
