HI, Currently I read that Twitter was hit by Virus! So did FB but not as bad. I want to know is it safe to go on FB when I have Norton internet security? Thnks

Do you mean Facebook? There has been reports of malware being spread on Facebook.

So really can't say, there is information you can find through Google, here is just one I pulled up
Surge in Facebook Malware - F-Secure Weblog : News from the Lab

In the end, up to user whether to visit types of sites or not

So is that mean that as long as I don't click on the link or download the program, it is safe? Advise thnks

Your antivirus 'should' protect you from downloading anything suspicious - you can visit the site, just be careful if you click on something, you are sure you want to

Thank you!
