I am running windows, and I woke up to a bunch of messages I hadn't sent. At this point I already know its a virus and I have changed all my passwords, but I'm not sure what do do about it. I have run virus scans (malwarebytes and the built in antivirus) and I deleted any threats that popped up. I just want to make sure that I'm safe and want to know if there is anything else I should do? (image link because I can't add images for some reason: Image)
