REQUEST

Could the OP, or someone knowledgeable on this type of situation, speculate on the ACTUAL mechanism of this attack? What did the OP actually do, that gave away his private key? Was it stolen from the computer's clip board (copy/paste?)

Knowing HOW this kind of stuff happens will make it easier for other people to be more secure.
Thanks

I'm still investigating, I'll update when I find the exact mechanism.

I've also just realised that the attacker took 120 Litecoin from me on the 22nd of September, so my computer had been compromised for at least 18 days.

Ouch man, that's shocking, 100 BTC hurts in anyone's book. You seriously need to speak to a lawyer and go to the authorities, at least for the formality of making a report. PS: These things are usually not random.. Unfortunately, most likely its someone you know.

The lesson for everyone else is: Any more than a couple thousand bucks in coins MUST be kept on a Ledger/Trezor.
And DONT use the same computer for Bitcoin wallets as you do for downloading torrents etc.. Too many people have been burnt this way.
Also do malware scans everyday. I use iObit Advanced System Care and iObit Malware Fighter and these have kept my computers clean for years, highly recommended!

I hope you get to the bottom of this Cry
