will simply a http link and not a https link indicate a possible malware or scam link, if you have any info on this , please give some explanation on this ?
Thanks!
Well.. http and not https simply indicates there is no encryption in the http packets coming on/off that link's server.
If the link points to a page that has HTTP where you have to insert user and passwords or credit cards -> IT IS A SCAM! because that information will be out in cleartext and somebody might be able to snatch it.
if the link points to a HTTP page that has only informations and data to display to you (a static website), then https is not strictly necessary and it does not indicate a scam necessarily.
if the link points to a page that has HTTPS there is encryption, but still don't be 100% sure and always investigate further!!!
