    This virus (PUP.Optional.Trovi) continues to get into my PC after I delete it using Malwarebytes.

    Did a Malwarebyte (premium) scan and found one threat; a Trovi Optional Pup!

    I followed the instructions step by step and word by word, and was being informed that nasty things were being removed from my system.

    On completion I did a Malwarebyte recheck and, surprise, the Trovi pup is still there!

    Why are these so difficult to remove. Shall try someone else as there must be someone out there who can remove these things.

    MB has been reporting “PUP.Optional.Trovi” for a couple of weeks now. In an attempt to make it go away I updated to -Software Information-
    Components Version: 1.0.236
    Update Package Version: 1.0.3350
    License: Premium

    Today I noticed an interesting correlation: At the exact moment I tell MB to quarantine the PUP my Chrome 64 crashes! This is repeatable! Wow!

    Just thought this audience might be interested.
