Hello. I just noticed this about an hour ago. There was nothing in the morning, but when I returned home from school, my friend messaged me saying I was sending ads to everyone on DC. I changed the password at the end, but I haven't opened my PC today. I suggested running a scan with Malwarebytes from the PC, and it found a trojan, Malpack, and neshta virus. It quarantined them all, but should I still format the PC? I just got it out of a new format.
