Windows got malware but scan found no threats
I use windows 11 on my laptop. I downloaded a game installer from some sketchy website and ran it despite the security warning. The installer just kept freezing so I eventually deleted it. This morning I woke up to notifications in my phone from google saying they signed me out of my windows device because they detected malware in my device and suspicious activity. All 3 of my google accounts. I also got emails from some apps and social medias that somebody tried to log in and told me to ignore if that wasn't me. The attacker got my instagram and posted a story of crypto scam and also my discord which they sent everyone a dm of crypto scams. I changed the passwords and terminated all other devices. I also saw an unknown device logged in my telegram so I terminated it. I'm pretty sure my phone is safe but it's my laptop that got malware but windows defender and malwarebytes scans keep coming out positive. Please help.
