I downloaded a virus by clicking on such an icon a few months ago. Again I also just got an update for Adobe Reader in my tray - I right clicked on it and deleted it but i don't know if that got it off my computer. I'm running Microsoft Security Essensials to see what it finds.
Thank you atir-husain for your response. I finally did go to the adobe page
and download the latest version of the Reader. I'm afraid to download
anything from the tray after I downloaded a virus by trusting that it was
actually Adobe when it wasn't.
After I downloaded the latest version the update did go away. I try to be
really careful now. I used to use AVG but after I got the virus I switched
to Security Essentials. I hope I don't have any more problems. Anyway thank
you for your help, I do appreciate it.
