Ok so this started when my friend sent me a file. I trust him but when I downloaded it, Trend Micro automatically deleted it so i just cancelled that and downloaded anyways. About 5 minutes later, my phone started playing the "Find My iPhone" sound and said "Find My iPhone alert". I was confused but ignored it. 2 minutes later my webcam light turned on for about 3 seconds and turned off. Right there I knew something was up so I asked my friend about it and he said that the file wasn't bad. I then disconnected from the internet (Airplane Mode) and did a Trend Micro Full Scan. This took 30 minutes and found no virus so I was confused. Later on, I kept getting Steam security codes on my phone which meant someone was logging into my steam account but they needed my security code from my phone. Also, apps on my computer keep opening and right now my gmail was just signed into and so was my microsoft please help quick
