Hi, I'm not sure why or how this has happened but, occasional a little box will pop up 'asking what i want to open this file with' without me actually clicking on anything. I can't remember what the main option was but the next time it pops up I will screen shot it and update! anyway when I click more options and then choose internet explorer it opens up the download box and shows that I'm actually about to download something called 'fiber.js.' Now I've looked online and this is a virus. however i have done countless scans on my laptop and they have come back with nothing. and apart from this popping up nothing bad is happening but I cant figure out why it keeps popping up and asking me to open the virus at what seems to be random points. Could anybody help? i would really appreciate it!
