give us script blocking
Script blocking is an exclusive virus detection technology that proactively protects against certain known and unknown threats without the need for virus definitions. Unlike other threats that still require virus definitions, this technology automatically blocks common script-based threats that arrive via email, such as the renowned "ILoveYou" and "AnnaKorunikova" viruses. Script blocking monitors scripts and alerts users to virus-like malicious behavior, stopping these viruses before they can infect a system.
