Yesterday the trainer worked fine, today MSE identifies "F:\Temp\~Mnn133.tmp" as "Backdoor:MSIL/Bladabindi!rfn", and deletes it, so the trainer can't run. Never had problem with AV and CH trainers before... Wonder, what behaviour of the CH trainer triggers the detection...
paste that file F:\Temp\~Mnn133.tmp in settings excluded files and locations file locations in MSE and your good to go
