Go ahead and d/l-**NEVER D/L AN "EXE" FILE** if you're just seeking audio/video-What the lock is for, is to let you know that that file is straight from L/W-this icon WILL NOT appear ,in most instances,when you search for movies or music-the files that return from the search are almost always from someone else on the GNUTELLA NETWORK, just like yourself-or meif you have ever D/L-ded any songs/video from disk to PC yourself, you should have an idea of the right size of the file you're searching for-AVOID ALL files that seem too large/small to be what you are looking for-they probabaly aren't anything good-from an unwanted toolbar, to a virus or trojan-If there's ANY doubt, simply use your virus/spyware program to scan the file before you open it- that'll help LOTS in finding bad stuff Idiots post to corrupt your sys.
