Sigh.

Trying to find a way to convert an NWC file to a PDF file for emailing, I stupidly downloaded and installed something I should not have, and the laptop is borked. Its own screen is black, but the connection to the telly is working. Managed to get into safe mode, and Malwarebytes Free is having a bash at it now. Thank frod I put the episodes up yesterday.

Ain't life a hoot.

EDIT: Malwarebytes did the trick. Avoid installing anything that offers you something called Vosteran as an optional extra. It's not that optional, and it's nasty. And if you already knew this and thought everyone did, please don't laugh at me too hard. We learn by doing.
