Trojan:Script/Wacatac.B!ml

[HippyCraig]

Sometime when I try to use SingleFile as soon as the file downloads Windows Security blocks it and I get an error

Trojan:Script/Wacatac.B!ml

now other pages on the same site dont do that but some started to reciently. There HTML files so I dont know why its getting picked up that way, I thought that virus was only related to EXE. and other excutable file types.
