I am new - so sorry if this is answered someplace else and I havent seen it. Yesterday I was looking thru a thread and checking out the link provided by other users. Two of the links were wanting to add software to my computer. I was alarmed and exited each time. Is there any way to know if I'm being directed to a site that's going to give my computer a virus or something? How do I know the link posted by a user isnt a malicious site? It seems that malicious is stuff is all over the internet (especially guised as porn), and I dont want to mess up my computer.
