I downloaded the new quicktime 7 from the apple website the other day and straight away, after installing it, my antivirus software tells me a file in the quicktime directory is a virus. Whenever I load a trailer, or any mov file I get this warning that there is a trojan. Its really annoying. The apple website should be safe shouldn't it? The file in question is something called Quicktimewebhelper.qtx and I'm using Nortons antivirus 2005. Is there anyting I can do? Thanks.
