Hi there. I recently clicked on a Discord verify link where I authorized a Discord app, which resulted in my account spamming server invites. I did not download any in the browser that I am aware of, nor did I run any PowerShell in the Run command. I did have 2-step verification on. I'm not sure if my computer is infected, but I want to be sure. I have took my computer offline and run Malwarebytes deep scan with the option of scan for rootkit option on. This resulted in no detection. I have changed my password on accounts that are important to me on a clean computer. I want to ask if FRST is a necessary step to take next. I am planning on running bitdefender and ESET scanner next to double verify. I hope not to have to nuke my computer with a fresh USB install, but I am not well-versed in cybersecurity. Any advice would be much appreciated. Thank you for reading my Reddit post.
