[Jaysds1]

Hey,

I'm a Sheridan College student that takes Computer Programming and I was required to download this. Recently, I've noticed the program got deleted from my PC because Microsoft thinks it's a threat as I have started researching why and not clear still.
Here's the site it directs me to: https://www.microsoft.com/security/portal/threat/encyclopedia/entry.aspx?name=Trojan%3aWin32%2fVarpes.J!plock&threatid=2147706743&enterprise=0
