Can there be a trojan virus on my iPhone?
Hello, Years ago, a friend of mine introduced a Trojan horse into my Windows computer. This was in 2018. When I logged out of my Instagram accounts yesterday, there was another account that wasn't mine. The name of this account is the account of the person who introduced a Trojan horse to me in 2018. Is my phone safe? How did that person do this? Please help.
