I did a search about the address 1EvVR9JcUGvP2S9bHKvs7EzkoeXR12NTyS on bitcoinwhoiswho.com and it seems that the scammer had stolen around 2.6 BTC/about 23,355 USD.
https://bitcoinwhoswho.com/address/1EvVR9JcUGvP2S9bHKvs7EzkoeXR12NTySThis address can be reported as scam on bitcoinwhosiwho.com,but additional evidence is needed,like screenshots,type of scam,etc.Perhaps OP can provide this info and report their address as scam.The stolen bitcoins most likely will never get returned,but other people should be aware about this scam.
It's a good idear to mark the address as scam, aswell as going to your local police and create a complaint. However, don't get your hopes up: the odds of actually getting your BTC back are very small (allmost nonexistant). Only if the scammer is caught and your local police is informed and connects this information to your legal complaint, you have a small chance of getting a small part of your funds back. If the thief mixes, coinjoins or exchanges to a privacy coin using an on-the-fly swap-site, the police won't even be able to follow the fund's trace, and if they ever catch the guy, odds are they'll never be able to pinpoint you as a victim.
Marking the address sounds a good idea however the scammer can easily transfer it to other address, a new one and just send it to another using btc mixers. The odds of recovering the funds is pretty impossible, and I doubt a police complaint would do so much for you coz I don't know how the police are going to locate the suspect for just using the address, they need to speak first with the cyber crime operatives for that.
Like it has been said before: it's more important NOT to trust your pc and learn the (expensive) lesson this ordeal has taught you. You should consider your pc to be infected, if you're not an expert there is no way of knowing if the thief installed other malware, disabled certain services, stole private info,... My best advice would be to start from scratch: clean OS, virusscanner, firewall + hardware wallet. You should never install any illegal or unknown program, script, plugin,.. on a PC that's being used for financial transactions (including crypto wallets), you should keep the attack vector as small as possible by only installing the binaries you truely need, and you should keep everything patched (and remove any app that's no longer actively supported).
Random hacking like this is probably because of unsafe and unsecured web browsing, this is a form of malware attack that has been downloaded to your device without you noticing it. This maybe not a good time to give you hopes anymore, that was embarrassing but you have to deal with it and move on afterwards.
