It was a normal home PC which is connected to the internet when on. Windows 10.
Wallet was encrypted with a fairly weak password I guess.
Windows Anti virus and anti malware. Normal firewall with modem. Pretty sure it was accessed through the internet.
Can anyone run a trace so I can find out which exchange traded the coins?
I may engage a crypto PI if there is a lead.
A lot of times such steals are inside job. So make sure to think also about that. Who had access to your computer. Not only in 2020. But also before. They could steal your private key in 2017 and then just withdraw last year, so would not look suspicious.
