You have to download metamask https://metamask.io/
You can then import your wallet and use the DApp browser to connect to the cumfarm
If you’re on iOS trust won’t work anymore, android is unaffected
If you never gave it out then either there was a violation in the authority transferring for you or you need to look at your machines for Trojans and malware. I would wipe my phone and create new wallets and transfer everything. Maybe my computer and tablet too. Also it helps if you have a router that has security functions. Such as IPS
After you wipe your devices install a VPN package such as NordVPN to them and set it to automatically connect after you join any Wi-Fi network. Make sure all the machines on your home network are white and cleaned. Scan them as well after you reload them.
And honestly this is the way you can stop feeling paranoid about it. You don't try to isolate the infection but assume it's a Trojan or worm that can spread via network and go ahead and clean everything. The router I have is a unify or ubiquity router and it performs honey trap and IPS security to keep attackers from breaking in to my individual devices. I then have my individual devices with VPN access on them. The router itself is on a dedicated VPN as well. I really don't have to worry about a break-in from via the ISP. I'm only one of them when I join public networks and I generally keep my wallet phone from being seen by any other devices. This keeps all the ports closed and it cannot be detected on the network for the most part. Even if it is it can't be communicated with via tcp/IP
