Thanks for help
I have a laptop which was running -ntl netguard-
this became dis-abled prompting me to re-install (no longer available- virgin media)
I installed F-secure client security
It has cleaned up except for a trojan it cannot clean or delete
It identifies another file - cryptdl.dll
I cannot delete manually
Trojan.win32.BHO.abo
