I would assume the worst. First copy the wallet.dat to a USB for safe keeping. Setup coinomi and send your entire balance to that asap. I can tell you I formatted my PC about an hour after word spread about how intrusive this trojan was. Other coins were hit, but denarius is still on peoples radars and has always been a target, so guess which coin hit the news.

Still unclear if a wallet.dat can get infected. But pretty easy to wall the QT wallet off in a VM using Oracle Virtual Box with unactivated Windows 10 ISO.

Either way you can run a VM, disconnect the internet and dump your wallet.dat private keys. And move those coins to a new address NOW.
