Norton Safe Web takes forever to scan Facebook Wall

Hi,

 

Recently, I have enabled my NIS 2011 (18.0.6.29) to scan my Facebook Wall posts, as I get some mails from Facebook supposedly sent by one of my "Friends". Though some were quite apparently spam / phishing mails, I suspect some were designed to lead the FB users to malicious websites. I got NIS 2011 to scan my Facebook Wall, but for over an hour it has been scanning and has just been displaying a message "Generating results...." with a yellow progress bar seemingly scanning the Wall posts. I am not very active on Facebook, so don't have much by way of Wall posts, hence wonder why Norton Safe Web has been taking so long to scan my Wall. Is this a known issue with NIS 2011 ?

 

Regards,

Ramesh
