Could anyone tell me if I am correct in thinking that if a folder is downloaded from the internet, which contains sub folders & files, any virus in the software is activated on opening a file rather than the folder or sub folder. I suspect that I have picked up a virus from a programme that I have downloaded. After opening the main folder I then opened a readme file, but not the exe. files, so I am hoping that is where the virus came from rather than the programme itself, as I do not want to have to delete the whole download.Thanks
