I turned off my adblocker to log in and upload my mod on Nexus Mods, and on the "my mods" page (if I remember correctly) I immediately got a malicious ad redirecting me to a fake antivirus website "securitypatch[.]life". I closed that thing immediately, sorry for not taking a screenshot and capturing any logs for you.
My machine is definitely not infected, all updates and security patches are installed regularly, and all antivirus features are turned on.
