SiloS02E10 virus

Just saw the new silo ep downloaded last night but wouldn't import into Sonarr after download so I opened the folder and saw the mkv was showing as a shortcut....very strange so I checked the properties and it's file path was leading to System32.....also this Ep was downloaded yesterday the only episode of the whole season that has been available prior to the actual air date......what's going on here? Tike to nuke the PC and start fresh?
