Turbo88,

There's NO free trial of LW from the official site. Scam sites might offer this but do you really want to download from a scam site??

LW basic is free. LW Pro costs $18.88 & includes free updates & email support for up to 6 months. There is no free trial for LW Pro because basic is free for everybody to use first, before they consider an upgrade to Pro. The only official site for downloading either version of LW is www.limewire.com

The orange warning banner was added because there's a bogus LW update showing up in search results. It's a 75.7 KB .exe & shows up as "Urgent LW update - download & install now". If people download that thing they could end up infected. To try to prevent careless people from downloading a dangerous file, the warning banner was added to LW's interface.

The padlock symbol doesn't apply to music or video etc.
