I received a message with the famous link My-love co via Whatsapp and I never clicked on the link; I blocked the contact and deleted the message containing it; such a link was reported as infected by the newspapers.
Despite the fact that I didn't click on it, a strange icon with the profile picture and the name of the person who sent it to me appeared in my home. I reset my phone then and reinstalled WhatsApp by recovering the backup of the chats.
No traces of the infected link in there (because I deleted the message before resetting the phone), so I was no longer worried about it and I sent a message to the contact. After that, I blocked him again to avoid the possibility of other infected messages.
Today that strange icon with his name and profile picture appears again on my home. I cannot find it in the APPs list.
I never clicked on any link and I did hardware reset, so my questions is:
Why such a virus is there and why it's still there even after the hardware reset? Is it possible that the infected Whatsapp account is able to spread the trojan simply by being there in the contact list of my phone or because I opened his message (even if I didn't click on the link)? Or might my SIM card be virus-infected instead?
