Is there such a thing as safe DownLoading?

i have an anti virus that I bought, but when sometimes I hit a link or
something on the internet, it will automatically detect a threat and it
shows like its scanning something like in red color, and it tells me to
install something, which is not even related to my anti virus, it seems
like theres something totally different that its scanning, like it says
anti virus threats scan, what is this? what should I do? 'unlock
iphone' (http://unlockiphone22.com)
